Objective: Although, earlier studies have evaluated the significance of various estradiol patterns during controlled ovarian hyperstimulation (COH), their prognostic significance remains unclear. The objective of this study is to investigate the rate of increase in estradiol (ROI-E2) during COH and evaluate it as a predictor of ovarian response. Materials and Methods: In this retrospective stud...

Medical image repositories contain very large amounts of computer tomography (CT) scans. When querying a particular CT scan, the user is often not interested in the complete scan but in a certain region of interest (ROI). Unfortunately, specifying the ROI in terms of scan coordinates is usually not an option because an ROI is usually specified w.r.t. the scan content, e.g. an example region in ...

PURPOSE To determine the reproducibility of TWIST-derived (Time-Resolved Angiography with Interleaved Stochastic Trajectories) quantitative dynamic contrast enhanced (DCE) MRI in a uterine fibroid model. MATERIALS AND METHODS The institutional review board approved this retrospective study. Dynamic contrast-enhanced TWIST datasets from 15 randomly selected 1.5 Tesla pelvic MR studies were pos...

Introduction:We evaluated the performance of muscle perfusion scan (MPS) to assess muscle perfusion reserve (MPR) for prediction of incident diabetic foot ulcerations (DFU). Methods: We recruited 41 diabetic patients without any history of DFU. Five mCi 99mTc-MIBI was injected intravenously during repetitive dorsal and plantar right foot flexions. T...

Hand tracking is one of the essential elements in vision based hand gesture recognition system. The tracked hand image can provide a meaningful gesture for more natural ways of Human Computer Interaction (HCI) systems. In this paper, we present a fast hand tracking method based on the fusion of skin and motion features incorporated covariance matrix. First, hand region is detected using a fusio...

Region-of-interest (ROI) image coding is an interesting feature in JPEG2000, which allows for encoding the ROIs in an image with better quality than the background (BG). Considering the limitations of two standard ROI coding methods, a new ROI coding method called generalized partial bitplanes shift (GPBShift) is presented in this paper. To control the relative importance between ROI and BG, th...
