AN EFFECTIVE AND EFFICIENT FEATURE SELECTION METHOD FOR LUNG CANCER DETECTIONijcsit
Medical image data is growing rapidly. Lung cancer considers to be the most common cause of death among people throughout the world. Early lung cancer detection can increase the chance of people survival. The 5 year survival rate for lung cancer patient increases from 14 to 49% if the disease is detected in time. Computed Tomography can be more efficient than X ray for detecting lung cancer in time. But the problem seemed to merge due to time constraint in detecting the presence of lung cancer.MAT LAB have been applied for the study of these techniques. Feature selection is a method to reduce the number of features in medical applications where the image has hundreds or thousands of features. In order to extract the accurate features of an image, an image need to be processed for its effective retreival.Image feature selection is an essential task for recognizing the image and it can be done for overcoming classification problems. However, the quality of the image recognition tasks can be improved with the help
of better classification accuracy for enhancing the retrieval performance.

Breast cancer is the most common cancer among women worldwide constituting more than 25%
of all cancer incidences occurring in the world [1]. Statistics show that US, India and China
account for more than one third of all breast cancer cases [2]. Also, there has been a steady
increase in the breast cancer incidence among young generation in the world. In India, one out of
two women die after being detected with breast cancer where as in China it is one in four and in
USA it is one in eight [2]. Therefore, the statistics show that cancer mortality is highest in India
among all other nations in the world. In US, though the number of women diagnosed with cancer
is more than that in India, their mortality
Feature selection/extraction methods aimed to reduce the Microarray data. Basically in this comparative analysis, we have taken into account different feature selection and extraction strategies used up till now in the field of Biomedical. In the field of pattern recognition and biomedical imaging, dimensionality reduction is the central area of the research. Some mostly used features selection/extraction methods aim to analyze the most efficient data and achieve the stable performance of the algorithms, as well as improve the accuracy and performance of the classifier. This analysis also highlights widely used dimensionality reduction techniques used up till now in the field of biomedical imaging for the purpose to explore their potency, and weak points.

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.

Computer aided diagnosis for liver cancer using statistical modeleSAT Journals
Abstract Liver Cancer is one of the most difficult cancer to cure and the number of deaths that it causes generally increasing. The signs and the symptoms of the liver cancer are not known, till the cancer is in its advanced stage. So, early detection is the main problem. If it is detected earlier then it can be helpful for the Medical treatment to limit the danger, but it is a challenging task due to the Cancer cell structure. Interpretation of Medical image is often difficult and time consuming, even for the experienced Physicians. Most traditional medical diagnosis systems founded needs huge quantity of training data and takes long processing time. Focused on the solution to these problems, a Medical Diagnosis System based on Hidden Markov Model (HMM) is presented. This paperdescribes a computer aided diagnosis system for liver cancer that detects the liver tumor at an early stage from the chest CT images. This automation process reduces the time complexity and increases the diagnosis confidence. Keywords—HMM, Segmentation, Feature Extraction.
Role of Breast Tomosynthesis in the Morphological Analysis of Breast LesionsApollo Hospitals
1. To assess the role of Breast Tomosynthesis (by 3D Combined View) versus 2D Full
Field Digital Mammogram alone in the morphological analysis of breast lesions.
2. To evaluate the potential role of Tomosynthesis in BIRADS Categorisation and Final
Histopathology.
In May 2011 we migrated from an Analogue Mammogram with a dedicated Mammogram
CR system to a Full Field Digital System with 3D Tomosynthesis.
In India there is no official screening programme. All screening is opportunistic, self-
initiated and self-funded. Most Mammograms done at our hospital, a Corporate Tertiary
care Oncology facility, are performed as Diagnostic Mammograms followed by mandatory Breast Ultrasound and additional views, if necessary, on the same day obviating the need for recall.
Reducing the number of cases for additional views and breast ultrasound will help
in decreasing the patient's waiting time, making reporting more efficient, without
compromising on the accuracy. We used BIRADS categorisation as an evaluating tool
and compared the BIRADS categorisation with the final HPE.

Ultrasound image segmentation through deep learning based improvised U-Netnooriasukmaningtyas
Thyroid nodule are fluid or solid lump that are formed within human’s gland and most thyroid nodule doesn’t show any symptom or any sign; moreover there are certain percentage of thyroid gland are cancerous and which could lead human into critical situation up to death. Hence, it is one of the important type of cancer and also it is important for detection of cancer. Ultrasound imaging is widely popular and frequently used tool for diagnosing thyroid cancer, however considering the wide application in clinical area such estimating size, shape and position of thyroid cancer. Further, it is important to design automatic and absolute segmentation for better detection and efficient diagnosis based on US-image. Segmentation of thyroid gland from the ultrasound image is quiet challenging task due to inhomogeneous structure and similar existence of intestine. Thyroid nodule can appear anywhere and have any kind of contrast, shape and size, hence segmentation process needs to designed carefully; several researcher have worked in designing the segmentation mechanism , however most of them were either semi-automatic or lack with performance metric, however it was suggested that U-Net possesses great accuracy. Hence, in this paper, we proposed improvised U-Net which focuses on shortcoming of U-Net, the main aim of this research work is to find the probable Region of interest and segment further. Furthermore, we develop High level and low-level feature map to avoid the low-resolution problem and information; later we develop dropout layer for further optimization. Moreover proposed model is evaluated considering the important metrics such as accuracy, Dice Coefficient, AUC, F1-measure and true positive; our proposed model performs better than the existing model.

A novel framework for efficient identification of brain cancer region from br...IJECEIAES
Diagnosis of brain cancer using existing imaging techniques, e.g., Magnetic Resonance Imaging (MRI) is shrouded with various degrees of challenges. At present, there are very few significant research models focusing on introducing some novel and unique solutions towards such problems of detection. Moreover, existing techniques are found to have lesser accuracy as compared to other detection schemes. Therefore, the proposed paper presents a framework that introduces a series of simple and computationally cost-effective techniques that have assisted in leveraging the accuracy level to a very higher degree. The proposed framework takes the input image and subjects it to non-conventional segmentation mechanism followed by optimizing the performance using directed acyclic graph, Bayesian Network, and neural network. The study outcome of the proposed system shows the significantly higher degree of accuracy in detection performance as compared to frequently existing approaches.
AUTOMATIC SEGMENTATION IN BREAST CANCER USING WATERSHED ALGORITHMijbesjournal
Accurate and reproducible delineation of breast lesions can be challenging, as the lesions may have complicated topological structures and heterogeneous intensity distributions. Diagnosis using magnetic resonance imaging (MRI) with an appropriate automatic segmentation algorithm can be a better imaging technique for the early detection of malignant breast tumours. The main objective of this system is to develop a method for automatic segmentation and the early detection of breast cancer based on the application of the watershed transform to MRI images. The algorithm was separated into three major sections: pre-processing, watershed and post-processing. After computing different segments, the final image was cleared of all noise and superimposed on the original MRI image to generate the final modified image. The algorithm successfully resulted in the automatic segmentation of the MRI images, and this can be a beneficial tool for the early detection of breast cancer. This study showed that the automatic results correctly agree with manual detection

New Noise Reduction Technique for Medical Ultrasound Imaging using Gabor Filt...CSCJournals
Ultrasound (US) imaging is an important medical diagnostic method, as it allows the examination of several internal body organs. However, its usefulness is diminished by signal dependent noise known as speckle noise. Speckle noise degrades target detectability in ultrasound images and reduces contrast and resolution, affecting the ability to identify normal and pathological tissue. For accurate diagnosis, it is important to remove this noise from ultrasound images. In this study, a new filtering technique is proposed for removing speckle noise from medical ultrasound images. It is based on Gabor filtering. Specifically, a preprocessing step is added before applying the Gabor filter. The proposed technique is applied to various ultrasound images, and certain measurement indexes are calculated, such as signal to noise ratio, peak signal to noise ratio, structure similarity index, and root mean square error, which are used for comparison. In particular, five widely used image enhancement techniques were applied to three types of ultrasound images (kidney, abdomen and ortho). The main objective of image enhancement is to obtain a highly detailed image, and in that respect, the proposed technique proved superior to other widely used filters.

Artificial neural network for cervical abnormalities detection on computed to...IAESIJAI
Cervical cancer is the second deadliest after breast cancer in Indonesia.
Sundry diagnostic imaging modalities had been used to decide the location
and severity of cervical cancer, one among those is computed tomography
(CT) Scan. This study handles a CT image dataset consisting of two
categories, abnormal cervical images of cervical cancer patients and normal
cervix images of patients with other diseases. It focuses on the ability of
segmentation and classification programs to localize cervical cancer areas
and classify images into normal and abnormal categories based on the
features contained in them. We conferred a novel methodology for the
contour detection round the cervical organ classified with artificial neural
network (ANN) which was employed to categorize the image data. The
segmentation algorithm used was a region-based snake model. The texture
features of the cervical image area were arranged in the form of gray level
co-occurrence matrix (GLCM). Support vector machine (SVM) had been
added to determine which algorithm was better for comparison.
Experimental results show that ANN model has better receiver operating
characteristic (ROC) parameter values than SVM model’s and existing
approach’s regarding 96.2% of sensitivity, 95.32% of specificity, and
95.75% of accuracy.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Automatic Nonlinear Filtering and Segmentation
for Breast Ultrasound Images
Mohamed Elawady, Ibrahim Sadek, Abd El Rahman
Shabayek, Gerard Pons, Sergi Ganau
PROBLEM DEFINITION
The ultrasound image contrast between the ab-
normality and the surrounding breast tissue is
insufficient for direct lesion detection.
CONTRIBUTION
• Introducing a fully automatic lesion ex-
traction algorithm.
• Proposing a fast segmentation step by
means of Quick Shift; against frequently
used Normalized Cut.
• Conducting a comparative study on the
most common preprocessing nonlinear
techniques.
METHOD
Figure 1: The proposed framework used for lesion segmentation in BUS images.
RESULTS I
Performance results across all proposed methods (segmentation [QS: Quick Shift and NC: Normal-
ized Cut] and preprocessing [FR: Frost Filter, DPAD: Detail Preserving Anisotropic Diffusion and
PPB: Probabilistic Patch-Based]):

RESULTS II
Results of some successful lesion extraction.
First row represents some of the input images.
Second, third and fourth rows show the output
results of [QS-FR, NC-DPAD, NC-PPB] respec-
tively, in which white color is true segmented
lesion, green color is false positive, red color is
false negative and black color is true negative.
The computation time of Quick Shift method
is 8x faster than Normalized Cut method.
The failure cases exist in all methods due to
the intensity similarity of surrounding tissues
around the target lesion, leading to incorrect
segmentation.

CONCLUSION
• Best performance: FR with QS, DPAD
with NC and PPB with NC.
• QS is a more preferable choice in real time
applications.
• Future work: use superpixel segmenta-
tion approaches for robust results.
