Axial proton density (PD) weighted magnetic resonance (MR) images of shoulder which has the ability to represent bone edema while preserving anatomical details, provides valuable information for the evaluation of traumatized shoulder. The low signal to noise ratio of PD weighted slices of MRI while being a powerful tool for the detection of the pathological conditions, can hamper the determination...
Proteomic analysis is a rapidly developing research field that has recently been used in the diagnosis and treatment of various diseases by analyzing the structure and functions of protein patterns in the cell. Numerous computer based decision support mechanisms implemented in this context have mostly used special image processing techniques until now. Recently, high performance self-learning deep...
Traumatic and degenerative shoulder pathologies of which treatment strategy and success depends on correct diagnosis are more commonly encountered at the present time. The aim of this study is to help clinicians by using computer based decision support systems to diagnose correctly the degenerative and traumatic conditions of shoulder from MR images which is not an easy task in practice. Image patches...
The objective of this research is to develop a computer-based diagnosis system which is capable of recognizing normal and edematous humeral head images by using texture features derived from Hermite transform. The performance of Hermite-based texture features in classification of humeral bone was compared with curvelet, contourlet and gray level co-occurrence matrix-based texture feature descriptors...
Bone edema is a nonspecific and reactive condition of bone which is easily detectable with PD weighted MRI. In this study we decomposed segmented PD weighted MR images of humeral head, based on finite discrete shearlet transform (FDST) which provides optimal multiscale and multidirectional representation of 2D signals. Afterwards shape features were extracted from coefficients of FDST based on Pyramid...
The purpose of this study is to segment the humeral head from two dimentional proton dansity(PD) magnetic resonance images (MRI) of shoulder. MRI studies of patients presenting with shoulder pain may demonstrate bone marrow edema and different degrees of contour changes. Computerised tomography(CT) and T1 weighted MR images demonstrate bone margins better. T2 or PD weighted images are poor in determining...
