during dental education, dental students learn how to examine patients, make diagnosis, plan treatment and perform dental procedures perfectly and efficiently. however, progresses in computer-based technologies including virtual reality (vr) simulators, augmented reality (ar) and computer aided design/computer aided manufacturing (cad/cam) systems have resulted in new modalities for instruction...

The main objective of the proposed research is to evaluate the invariance of the cooccurrence texture model with respect to patient size in Computed Tomography (CT) data. Since patients’ scans can have high variation in pixel spacing, in order to standardize all patients’ texture descriptors, we investigate the effect of four interpolation techniques in reducing the pixel spacing variance: near...

The purpose of this study was to investigate an information theoretic approach to feature selection for computer-aided diagnosis (CAD). The approach is based on the mutual information (MI) concept. MI measures the general dependence of random variables without making any assumptions about the nature of their underlying relationships. Consequently, MI can potentially offer some advantages over f...

Uterine myoma and adenomyoma are the most common benign tumors of the uterus. Ultrasound Imaging is the widely used method in the diagnosis of both the disease conditions; however the diagnosis strongly depends on the physician’s expertise and ultrasound system quality. These drawbacks have motivated the development of computer aided applications for the quantitative analysis of ultrasound imag...

The interpretation of ultrasound images remains a difficult task and the opinion of different doctors is generally not unequivocal. Therefore, there is a growing interest in the field of computer-aided diagnosis. In the field of medical image processing, computer-aided diagnosis includes image enhancement to facilitate visual interpretation, automatic indication of affected areas, organs and ot...
