Background: Content Based Image Retrieval (CBIR) has always been a demanding research area as it involves searching of digital images from the collection of images. Difficulty exists in retrieving images for the query posed by concentrating on the factors; computational complexity and accuracy. Though many research works span around CBIR, Content Based Medical Image Retrieval (CBMIR) plays a vital role in the area Read More

Introduction: A Wireless Body Area Sensor Network (WBASN) implements wearable devices interconnected with each other and connected to a central monitor acting as a Base Station. Ensuring data security and secure communication is challenging due to resource constrained environment. Secure communication is ensured with cryptography which requires good key generation techniques. Objective: A biometr Read More

Background: Atherosclerosis is the systemic disease responsible for most of the cardiovascular diseases. Increased Intima-Media Thickness (IMT) of carotid artery is a validated indicator of disease progression and cardiovascular risk. Methods: In this work an automatic segmentation technique is attempted to improve and preserve the inter-region edges in B-mode longitudinal ultrasound images of Common Carotid Arteries (CCA).

Background: Echocardiography is a rapidly developing area of research in medical imaging. It is also called an echo test or heart ultrasound which captures moving picture of the heart using sound waves and is a potential alternative to other imaging modalities as far as the advantage is concerned. Discussion: The new generation echocardiography scanners have the ability to acquire dense image volumes either real tim Read More

Background: Ultrasound (US) has been widely adopted as a user friendly, easily available imaging modality in the assessment of various musculoskeletal pathologies. Discussion: Recently, a new application of US, US elastography (USE) has emerged as a novel tool to evaluate the elasticity of tissues. This technique has been widely employed in the assessment of pathologies of the thyroid, breast, liver, prostate and Read More

Background: Image guided core needle biopsy (CNB) is an important tool in the management of musculoskeletal neoplasms. Although the diagnostic yield and accuracy of this procedure are high, non-diagnostic results can occur. A non-diagnostic CNB result can cause unnecessary patient and physician anxiety and can lead to repeat biopsy and delay in treatment. Knowledge of the radiologic and histologic factors a Read More

Purpose: The aim of this article is to provide an updated review of the literatures and give a summary of the evidences supporting the technical mechanism, indications, results and influential factors associated with automated percutaneous lumbar discectomy (APLD) for the treatment of symptomatic contained disc herniation. Methods: We searched the databases of PubMed and EMBASE for articles written in English and Read More

Objective: In the course of clinical treatment, several medical media are required by a physician in order to provide accurate and complete information about a patient. Medical image registration techniques can provide a richer diagnosis and treatment information to doctors and to provide a comprehensive reference source for the researchers involved in image registration as an optimization problem. Methods: The Read More

Introduction: One of the most challenging tasks in computer-aided diagnosis (CAD) is mapping of radiological features to image descriptors. If the descriptors chosen are not appropriate to discriminate a disorder from another, the role of CAD system may not be appreciable. Methods: A better idea could be to extract all the features that are felt to have significance in discrimination and then apply a feature selection algorithm t Read More

Background: In Magnetic Resonance Imaging, inhomogeneity of the static magnetic field lead to perturbations in the resulting images, called artifacts. Artifact generated by the magnetic metal is a significant problem of medical equipment used in the nuclear magnetic environment. Our goal is to present a method, assuming the field disturbances are known, to construct the resulting images based on the actual principle Read More

Background: Recently, Magnetic Resonance Imaging (MRI) of brain is used widely in the clinical applications for the detection of abnormalities such as tumor. Methods: Accurate segmentation of the affected regions in the brain MRI image plays a vital role in the quantitative image analysis to detect the location of tumor in the brain. However, many segmentation algorithms suffer from limited accuracy, due to the presence of Read More

Objectives: Our aim was to identify ultrasound criteria that may be used to detect portal vein stenosis (PVS) in adult living donor liver transplantation (ALDLT) with left lobe grafts. Methods: 171 recipients underwent primary left lobe graft aldlt and routine liver doppler ultrasound (DUS) as protocol. Another 151 right lobe liver donors who underwent pre-transplant and 6- month follow-up post-hepatectomy dus wer Read More

Introduction: The purpose of this study was to obtain normal values for muscle thickness (MT) and echogenicity of orofacial muscles in infants between 6 months and 5 years old. The data may be compared with data of patients with a neuromuscular disorder (NMD) to differentiate between healthy infants and patients and to explain oromotor dysfunction. Aims of this study were to provide normal values for the thickness of t Read More

Background: Lung cancer is the leading cause of cancer death and it is identified at the ending stage of the severity. The differentiation between lesions and its background tissues are difficult task due to its low contrast between lesions and its background tissues. Lesion characterization is also a difficult task due to similar texture pattern between the lung tumors and normal lung tissues. Methods: In this paper, the compute Read More

Background: Bone marrow edema-like lesions (BMLs) is a kind of bone disease due to excessive stress in the joints. The abnormal joint stress may be caused by pathological changes of the knee joint. Therefore, assessment of the relationship between the pathological state of the knee joints and BMLs is helpful to understand the pathological process of osteoarthritis (OA). Objective: To investigate pathogenic factors that are re Read More

Objective: To design ARMA model for the analysis of histopathology images. Background: In traditional cancer diagnosis using clinical pathology, pathologists examine biopsy samples and analyzes it on the basis of cell structure and tissue arrangement. This has unpredictability in ontogenesis and in positioning. Methods: These methods have been replaced by computer assisted diagnostics (CAD) that support impartial judgmen Read More
