This study aims to compare the cerebrospinal fluid spaces of normal rabbits and hydrocephalus models using image reconstruction software. Both manual and automated segmentation methods were used to perform 3D reconstruction of the ventricular system in vivo and ex vivo. The goal is to reveal the normal and hydrocephalus subarachnoid spaces using these software applications to improve hydrocephalus treatment. Imaging modalities like MRI and 3D angiography were used along with image reconstruction software to analyze hydrocephalus. There are still challenges to address regarding small animal ex vivo MRI acquisition and tissue preparation.
3D bio-printing is a process that uses 3D printing technologies to create cell patterns in a confined space while preserving cell function and viability. It works by layering liquid mixtures of cells and nutrients to structure tissue-like constructs for medical and tissue engineering uses. Some key developments include the first artificial bladder and trachea built by bio-printing in 2006 and 2011. The process generally involves pre-bio-printing to create models, bio-printing to structure cells using patient scans, and post-bio-printing to create stable structures. Applications include using bio-printed tissues for transplants, drug research, and eventually fully functional human organs.

Lumbar disk 3D modeling from limited number of MRI axial slices IJECEIAES
This paper studies the problem of clinical MRI analysis in the field of lumbar intervertebral disk herniation diagnosis. It discusses the possibility of assisting radiologists in reading the patient's MRI images by constructing a 3D model for the region of interest using simple computer vision methods. We use axial MRI slices of the lumbar area. The proposed framework works with a very small number of MRI slices and goes through three main stages. Namely, the region of interest extraction and enhancement, inter-slice interpolation, and 3D model construction. We use the Marching Cubes algorithm to construct the 3D model of the region of interest. The validation of our 3D models is based on a radiologist's analysis of the models. We tested the proposed 3D model construction on 83 cases and We have a 95% accuracy according to the radiologist evaluation. This study shows that 3D model construction can greatly ease the task of the radiologist which enhances the working experience. This leads eventually to a more accurate and easy diagnosis process.
This study evaluated the feasibility of using 3D printing to create models from neuroimaging data to aid in medical education and patient communication.

Their next steps are to print the tissues together using different materials. Once optimized, they plan to assess if 3D printed models improve training for medical students and clinicians in neuropathology.
Retinal Vessels Segmentation Using Supervised Classifiers for Identification ...IOSR Journals
The risk of cardio vascular diseases can be identified by measuring the retinal blood vessel. The
identification of wrong blood vessel may result in wrong clinical diagnosis. This proposed system addresses the
problem of identifying the true vessel by vascular structure segmentation. In this proposed model the segmented
vascular structure is modelled as a vessel segment graph and the true vessels are identified by using supervised
classifier approach. This paper proposes a post processing step in diagnose cardiovascular diseases which can
be identified by tracking a true vessel from the optimal forest in the graph given a set on constraints.

Segmentation and Classification of Brain MRI Images Using Improved Logismos-B...IJERA Editor
Automated reconstruction and diagnosis of brain MRI images is one of the most challenging problems in medical imaging. Accurate segmentation of MRI images is a key step in contouring during radiotherapy analysis. Computed tomography (CT) and Magnetic resonance (MR) imaging are the most widely used radiographic techniques in diagnosis and treatment planning. Segmentation techniques used for the brain Magnetic Resonance Imaging (MRI) is one of the methods used by the radiographer to detect any abnormality specifically in brain. The method also identifies important regions in brain such as white matter (WM), gray matter (GM) and cerebrospinal fluid spaces (CSF). These regions are significant for physician or radiographer to analyze and diagnose the disease. We propose a novel clustering algorithm, improved LOGISMOS-B to classify tissue regions based on probabilistic tissue classification, generalized gradient vector flows with cost and distance function. The LOGISMOS graph segmentation framework. Expand the framework to allow regionally-aware graph construction and segmentation.
This document presents a method for liver segmentation using a 2D U-Net model. The method first preprocesses CT scan images using techniques like windowing, masking, normalization, and morphological operations. It then trains a 2D U-Net model on slices containing liver regions only, in order to focus modeling on liver segmentation. To improve inference performance on full volumes which may contain non-liver slices, the method uses histogram analysis to roughly select a range of slices likely to contain liver, such as the central 40% of slices. Evaluation shows this rough selection approach improves segmentation accuracy compared to applying the model to full volumes directly.
BRAIN TUMOR MRI IMAGE SEGMENTATION AND DETECTION IN IMAGE PROCESSINGDharshika Shreeganesh
Image processing is an active research area in which medical image processing is a highly challenging field. Medical imaging
techniques are used to image the inner portions of the human body for medical diagnosis. Brain tumor is a serious life altering
disease condition. Image segmentation plays a significant role in image processing as it helps in the extraction of suspicious regions
from the medical images. In this paper we have proposed segmentation of brain MRI image using K-means clustering algorithm
followed by morphological filtering which avoids the misclustered regions that can inevitably be formed after segmentation of the brain MRI image for detection of tumor location.
A New Algorithm for Fully Automatic Brain Tumor Segmentation with 3-D Convolu...Christopher Mehdi Elamri
This document describes a new algorithm for fully automatic brain tumor segmentation using 3D convolutional neural networks. The algorithm uses 3D convolutional filters to preserve spatial information, and a high-bias CNN architecture to increase effective data size and reduce model variance. On a dataset of 274 brain MR images, the algorithm achieved a median Dice score of 89% for whole tumor segmentation, significantly outperforming past methods. This demonstrates the effectiveness of generalizing low-bias high-variance methods like CNNs to learn from medium-sized datasets.

3D bio-printing involves using 3D printers to print biological materials and living cells in a layer-by-layer process to create living tissues and organs. It aims to address the shortage of organs available for transplant by creating organs customized for each patient using their own cells to prevent rejection. While the concept is simple, bio-printing is challenging due to the need to print multiple cell types and keep the cells alive. Researchers are working to modify bio-printers to deposit cells and nurturing gels accurately according to 3D models of organs in order to eventually print transplantable tissues and organs.

Stem cell therapy and organoid and 3D bioprintingCandy Swift
This document discusses two emerging techniques in cell therapy: organoids and 3D bioprinting. Organoids are 3D organ models derived from stem cells that mimic native tissue structures and physiology. They allow study of biological processes and have applications in transplantation, research, disease modeling, and drug testing. 3D bioprinting precisely creates living tissues and organs by combining cells, growth factors, and biomaterials in a layer-by-layer process. It has potential applications to produce tissues like skin, bone and blood vessels for transplantation and regenerative medicine. Both organoids and 3D bioprinting are establishing as critical tools in biological research with significant implications for clinical applications.

Whether due to illness or injury, organ failure is a worldwide problem and its only treatment is organ transplantation or tissue replacement. Although it’s the only solution in these cases, organs demand greatly surpasses the supply. Organs are usually obtained from people who recently have died (up to 24 hours past the cessation of heartbeat) or from people who are clinically brain dead and their body functions are maintained artificially, nevertheless living organ donation is becoming more frequent [1]. The increase of the organ demand has been raising ethical concerns, since this can result in offers or incentives for donation, profit on donated human organs or even exploitation of the disadvantaged. In the developed world most countries have a legal system that oversee organ transplantation, however in poorer countries a black market has been arising, enabling those who can afford to buy organs, exploiting those who are desperate enough to sell them
Bone Cancer Detection using AlexNet and VGG16IRJET Journal
The document presents a methodology for detecting bone cancer using deep learning models AlexNet and VGG16. CT scan images are preprocessed using smoothing, averaging and Canny edge detection filters. Features are extracted from the images and classified using AlexNet and VGG16 convolutional neural networks. The results show that VGG16 achieves higher accuracy compared to AlexNet in classifying images as non-cancerous (99.995% vs 88.34%) and stage 1 cancer (99.998% vs 72.28%). Both models achieve 100% accuracy in classifying stage 2 cancer images. VGG16 performs better than AlexNet for bone cancer detection and classification.
3 d printing of pharmaceuticals by nishunishuyadav17
The document discusses 3D printing of pharmaceuticals. It begins with definitions of 3D printing and describes the basic 3D printing process of designing an object digitally, exporting the file, and fabricating the object through successive layers of material. Current trends and an example of a 3D printed drug tablet are mentioned. Advantages include reduced production time and costs. Applications discussed include organ and tissue engineering, medical research and education, surgical planning, and drug delivery through 3D printed devices. The future of 3D printing in India is promising with a projected growth of 20% and establishment of new facilities.
3D bioprinting is a technique that uses 3D printing technologies to precisely position biological materials, cells, and biochemicals in layers to fabricate 3D structures and tissues. The process involves imaging tissues to create digital models, selecting appropriate biomaterials, cell sources, and a bioprinting method (inkjet, microextrusion, or laser). Applications include producing skin, blood vessels, and other tissues for implantation and drug testing. However, fully functional 3D printed organs are still in development due to challenges with vascularization and matching native tissue complexity.
