automatic detection of pulmonary nodules in lung ct imagesWookjin Choi
The document discusses lung cancer detection using CT scans and pulmonary nodule detection systems. It describes how CT scans are used to detect lung nodules early and increase survival rates. It then discusses the challenges of evaluating large CT data sets and the use of pulmonary nodule detection CAD systems to assist radiologists. The document goes on to describe a proposed CAD system that includes lung segmentation, nodule candidate detection using multi-thresholding and feature extraction, and a genetic programming based classifier to analyze features and detect nodules. Experimental results on a publicly available lung image database show the system achieved over 80% accuracy on test data for nodule detection.
Early detection of cancer is the most promising way to enhance a patient's chance for survival. This paper presents a computer-aided classification method using computed tomography (CT) images of the lung based on ensemble of three classifiers including MLP, KNN and SVM. In this study, the entire lung is first segmented from the CT images and specific features like Roundness, Circularity, Compactness, Ellipticity, and Eccentricity are calculated from the segmented images. These morphological features are used for classification process in a way that each classifier makes its own decision. Finally, majority voting method is used to combine decisions of this ensemble system. The performance of this system is evaluated using 60 CT scans collected by Lung Image Database Consortium (LIDC) and the results show good improvement in diagnosing of pulmonary nodules.
This document presents a novel technique for detecting the breast boundary (also known as the skin-air interface or skin-line) in mammogram images using entropy estimation.

Segmentation and Classification of Skin Lesions Based on Texture FeaturesIJERA Editor
Skin cancer is the most common type of cancer and represents 50% all new cancers detected each year. The deadliest form of skin cancer is melanoma and its incidence has been rising at a rate of 3% per year. Due to the costs for dermatologists to monitor every patient, there is a need for an computerized system to evaluate a patient‘s risk of melanoma using images of their skin lesions captured using a standard digital camera. In Proposed method, a novel texture-based skin lesion segmentation algorithm is used and to classify the stages of skin cancer using probabilistic neural network. Probabilistic neural network will give better performance in this system to detect a lot of stages in skin lesion. To extract the characteristics from various skin lesions and its united features gives better classification with new approached probabilistic neural network. There are five different skin lesions commonly grouped as Actinic Keratosis (AK), Basal Cell Carcinoma (BCC), Melanocytic Nevus / Mole (ML), Squamous Cell Carcinoma (SCC), Seborrhoeic Keratosis (SK). The system will be used to classify the queried images automatically to decide the stages of abnormality. The lesion diagnosis system involves two stages of process such as training and classification. Feature selection is used in the classified framework that chooses the most relevant feature subsets at each node of the hierarchy. An automatic classifier will be used for classification based on learning with some training samples of each stage. The accuracy of the proposed neural scheme is higher in discriminating cancer and pre-malignant lesions from benign skin lesions, and it attains an total classification accuracy is high of skin lesions.

Computer-aided diagnosis system for breast cancer based on the Gabor filter ...IJECEIAES
The most prominent reason for the death of women all over the world is breast cancer. Early detection of cancer helps to lower the death rate. Mammography scans determine breast tumors in the first stage. As the mammograms have slight contrast, thus, it is a blur to the radiologist to recognize micro growths. A computer-aided diagnostic system is a powerful tool for understanding mammograms. Also, the specialist helps determine the presence of the breast lesion and distinguish between the normal area and the mass. In this paper, the Gabor filter is presented as a key step in building a diagnostic system. It is considered a sufficient method to extract the features. That helps us to avoid tumor classification difficulties and false-positive reduction. The linear support vector machine technique is used in this system for results classification. To improve the results, adaptive histogram equalization pre-processing procedure is employed. Mini-MIAS database utilized to evaluate this method. The highest accuracy, sensitivity, and specificity achieved are 98.7%, 98%, 99%, respectively, at the region of interest (30×30). The results have demonstrated the efficacy and accuracy of the proposed method of helping the radiologist on diagnosing breast cancer.
The poster was presented at the SPIE Conference held at San Diego in February, 2016. To stratify low-risk patients of Oral Cavity Cancer for recurrence, this work hypothesized the quantification of 3D models from serial histology.

Microangiopathic Hemolytic Anemia refers to thrombotic microangiopathy which involves blood clots in small blood vessels along with hemolysis and symptoms of clotting. There are three types - thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome (HUS), and disseminated intravascular coagulation (DIC). TTP and HUS specifically present with microangiopathic hemolytic anemia, thrombocytopenia, and symptoms of clotting. TTP typically affects the central nervous system systemically while HUS is limited to the kidneys. The cause of TTP is often a genetic deficiency in the enzyme ADAMTS13
This document discusses techniques used to study lymphomas, including immunophenotyping, cytogenetics, and molecular analysis. Immunophenotyping helps differentiate between benign and malignant processes and between B and T cell neoplasms by identifying cell surface markers. Cytogenetics identifies translocations and deletions that help classify lymphomas. Molecular analysis identifies immunoglobulin and T-cell receptor gene rearrangements in B and T cell malignancies, respectively. The document also summarizes the history of lymphoma classification systems and the current WHO system, which classifies lymphomas based on morphology, immunophenotype, molecular abnormalities, and clinical profile.
1) Day case anesthesia, also known as ambulatory surgery or same-day surgery, allows patients to be admitted for a surgical procedure and investigation but return home the same day without an overnight hospital stay.
2) There has been a rapid expansion in the use of day case surgery over the last 30 years, with approximately 65% of surgeries in the United States now performed on an outpatient basis.
3) Day case anesthesia provides advantages like reduced costs, increased bed availability, and less risk of hospital-acquired infections compared to traditional inpatient surgery.
Molecular pathology of lymphoma by dr ramesh Ramesh Purohit
Lymphoma classification is based on the cell of origin (B-cell, T-cell, NK-cell). Molecular biology techniques including immunophenotyping and genetic studies are important for accurate diagnosis and classification. Immunophenotyping uses cell surface markers identified by clusters of differentiation (CD markers) to determine the cell lineage and stage of differentiation. Common CD markers for B-cells, T-cells, myeloid cells and other lineages are described. Molecular studies can identify genetic abnormalities that help classify specific lymphoma subtypes. Together these molecular techniques provide crucial information beyond what is visible by microscopy alone.

Finally, it provides a tentative schedule and references. The goal is to improve classification performance by utilizing a hybrid machine learning approach.
There are three major complications of diabetes which lead to blindness. They are retinopathy, cataracts, and glaucoma among which diabetic retinopathy is considered as the most serious complication affecting the blood vessels in the retina. Diabetic retinopathy (DR) occurs when tiny vessels swell and leak fluid or abnormal new blood vessels grow hampering normal vision.
Diabetic retinopathy is a widespread problem of visual impairment. The abnormalities like microaneurysms, hemorrhages and exudates are the key symptoms which play an important role in diagnosis of diabetic retinopathy. Early detection of these abnormalities may prevent the blurred vision or vision loss due to diabetic retinopathy. Basically exudates are lipid lesions able to be seen in optical images. Exudates are categorized into hard exudates and soft exudates based on its appearance. Hard exudates come out as intense yellow regions and soft exudates have fuzzy manifestations. Automatic detection of exudates may aid ophthalmologists in diagnosis of diabetic retinopathy and its early treatment. Fig. 1 shows the key symptoms of diabetic retinopathy.
CANCER CLUMPS DETECTION USING IMAGE PROCESSING BASED ON CELL COUNTINGIRJET Journal
This document describes a proposed method for detecting cancer clumps using image processing techniques including cell counting. The method involves preprocessing images using techniques like grayscaling, binarization, and edge detection. Cancer cells are then identified and segmented. Features are extracted from the segmented regions and fed into a deep learning model for classification and counting of cancer cells. The proposed approach aims to automatically detect cancer cells in images as a way to help speed up cancer research and improve accuracy over existing methods. If successfully implemented and refined with feedback, it could open new avenues for cancer cell detection in medical imaging.
Abstract:
A technique for exudate detectionin fundus image is been presented in this paper. Due to diabetic retinopathy an abnormality is caused known as exudates.The loss of vision can be prevented by detecting the exudates as early as possible. The work mainly aims at detecting exudates which is present in the green channel of the RGB image by applying few preprocessing steps, DWT and feature extraction. The extracted features are fed to 3 different classifiers such as KNN, SVM and NN. Based on the classifier result if an exudate is present the extraction of exudate ROI is done based on canny edge detection followed by morphological operations. The severity of the exudates is established on the area of the detected exudate.
Keywords:Exudates, Fundus image, Diabetic retinopathy, DWT, KNN, SVM, NN, Canny edge detection, Morphological operations.

Novel Functional Delta-Radiomics for Predicting Overall Survival in Lung Canc...Wookjin Choi
AAPM2023_SU-300-IePD-F6-4
Purpose: Traditional methods of evaluating cardiotoxicity rely on cardiac radiation doses and do not incorporate functional imaging. Cardiac functional imaging can improve the ability to provide early prediction for clinical outcomes for lung cancer patients undergoing radiotherapy. FDG-based PET/CT imaging is routinely obtained for staging and disease assessment after treatment. Although FDG PET/CT scans are typically used to evaluate the tumor, studies have shown that the PET cardiac signal is predictive of clinical outcomes. Our study aimed to develop novel functional cardiac delta radiomics using pre and post-treatment FDG PET/CT scans to predict for overall survival (OS).
Methods: We conducted a study of 109 lung cancer patients who underwent standard FDG-PET/CT scans pre- and post-radiotherapy. Data from ACRIN 6668 (N=70) and an investigator-initiated lung cancer trial (N=39) for functional avoidance radiotherapy were used. The heart was delineated, and 200 cardiac CT and PET functional radiomics features were selected. Delta radiomics was calculated as the change between pre- and post-PET/CT. The data were divided into 80%/20% training/test set, and feature reduction was performed using Wilcoxon test, hierarchical clustering, and recursive feature elimination. A Gradient Boosting Classifier machine learning model evaluated the ability of the delta PET/CT cardiac radiomics to predict for OS using 10-fold cross-validation for training and area-under-the-curve (AUC) for model assessment.
Results: Median survival was 431 days (range 144 to 1640 days). 4 clinically relevant delta features were identified: pre-CT_Maximum, post-CT_Minimum, delta-CT_GLRM_Run_Variance, delta-PET_GLRM_Run_Entropy. The model showed an AUC of 0.91 on the training set and an AUC of 0.87 on the test set.
Conclusion: This is the first study to evaluate functional cardiac delta radiomic features from standard PET/CT scans with data showing good predictive AUC for OS. If validated, this work provides automated methods to provide functional cardiac information for clinical outcome prediction in lung cancer patients.

Optimal fuzzy rule based pulmonary nodule detectionWookjin Choi
The document describes a lung cancer detection system that uses CT scans. It discusses (1) segmenting the lungs from CT images using adaptive thresholding and connected component analysis, (2) detecting nodule candidate regions using multi-thresholding and rule-based pruning, and (3) optimizing the rule-based pruning using a genetic algorithm trained fuzzy inference system to reduce false positives while maintaining high sensitivity. Experimental results on a publicly available lung image database show the optimized fuzzy system achieved better performance than a conventional rule-based approach.
This document summarizes research on vessel recognition in color Doppler ultrasound imaging. It begins with an introduction describing the goal of applying image analysis techniques to automate blood vessel segmentation. It then outlines the various steps taken: shape decomposition for vessel segmentation, fringeline tracking for phase unwrapping to address aliasing artifacts, generation and selection of vessel features, and vessel classification. The results of each step are presented, including vessel segmentation examples, phase unwrapping validation, and statistical analysis demonstrating improved success rates over other algorithms. In conclusion, the phase unwrapping is described as a building block for more advanced vessel recognition and quantification applications using color Doppler ultrasound images.
Digital radiography provides several advantages over film radiography including improved archiving and distribution of images, higher patient throughput, and potential reduction of patient radiation dose. There are two main types of digital radiography - computed radiography which uses imaging plates and direct radiography which involves intrinsic readout processes without cassettes. Direct radiography can be via direct or indirect conversion and uses flat panel detectors incorporating thin film transistors. Digital images allow various processing techniques and can be stored and shared electronically in picture archiving systems.
Microcalcification Enhancement in Digital MammogramNashid Alam
The document discusses early detection of breast cancer through computer-aided detection of microcalcifications in digital mammograms.

This document proposes a noninvasive method to detect diabetes mellitus using facial images. It extracts texture features using a Gabor filter bank and color features in the Lab color space from divided facial blocks. These features are classified using k-NN and SVM algorithms. Experimental results show classification accuracies up to 94.28% for k-NN and 97.14% for SVM, providing an alternative to invasive blood glucose tests. The method aims to detect differences in facial skin associated with diabetes status based on traditional Chinese medicine hypotheses.
Radiomics and Deep Learning for Lung Cancer ScreeningWookjin Choi
The document summarizes research on using radiomics and deep learning approaches for lung cancer screening. It describes:
1) Using radiomic features like shape, texture, and intensity from lung nodules on CT scans and an SVM-LASSO model to classify nodules with 87.9% sensitivity and 78.2% specificity, outperforming the Lung-RADS system.
2) A deep learning model developed for a Kaggle competition that achieved 67.4% accuracy on nodule classification but only ranked 99th due to overfitting issues without enough data.
3) Future work could integrate quantification of nodule characteristics like spiculation with plasma biomarkers to improve diagnostic accuracy.
This document proposes a computer-aided lung cancer classification system using curvelet features and an ensemble classifier. It first pre-processes CT images using adaptive histogram equalization to improve contrast. Then it segments the images using kernelized fuzzy c-means clustering. Curvelet features are extracted from the segmented regions and an ensemble classifier is applied to classify regions as benign or malignant. The proposed approach achieves reliable and accurate classification results compared to existing methods, with better performance metrics like accuracy, sensitivity and specificity.
Contourlet Transform Based Method For Medical Image DenoisingCSCJournals
Noise is an important factor of the medical image quality, because the high noise of medical imaging will not give us the useful information of the medical diagnosis. Basically, medical diagnosis is based on normal or abnormal information provided diagnose conclusion. In this paper, we proposed a denoising algorithm based on Contourlet transform for medical images. Contourlet transform is an extension of the wavelet transform in two dimensions using the multiscale and directional filter banks. The Contourlet transform has the advantages of multiscale and time-frequency-localization properties of wavelets, but also provides a high degree of directionality. For verifying the denoising performance of the Contourlet transform, two kinds of noise are added into our samples; Gaussian noise and speckle noise. Soft thresholding value for the Contourlet coefficients of noisy image is computed. Finally, the experimental results of proposed algorithm are compared with the results of wavelet transform. We found that the proposed algorithm has achieved acceptable results compared with those achieved by wavelet transform.
In this paper, cysts are detected in the ultrasonic images of ovary. PCOS is an endocrine disorder affecting women of reproductive age. This syndrome is mainly seen in women whose age is in between 25 and 35. We are proposing methods for identifying whether a person is suffering from Polycystic Ovary Syndrome (PCOS) or not. Ultrasound imaging of the follicles gives important information about the size, number and mode of arrangement of follicles, position and response to hormonal stimulation. A thresholding function is applied for denoising the image in the wavelet domain. Before the segmentation process the ultrasonic image is preprocessed using contrast enhancement technique. Morphological approach is used for implementing contrast enhancement. This is performed in order to improve the clarity and quality of the image. Fuzzy c-means clustering algorithm is applied to the resultant image. Finally the cysts are detected with the help of clusters. The efficiency of the algorithm depends upon the value of Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR).
Computer aided detection of pulmonary nodules using genetic programmingWookjin Choi
This document describes a method for detecting pulmonary nodules in CT scans using genetic programming. It first segments the lung regions from CT images and extracts nodule candidates. Features are then extracted from the candidates. Genetic programming is used to classify candidates as nodules or non-nodules by optimizing combinations of features. The method was tested on a publicly available lung image database, achieving a true positive rate of over 90% and low false positive rate.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.
