The roles of physicists in medical imaging have expanded over the years, from the study of
imaging systems (sources and detectors) and dose to the assessment of image quality and …

Computed tomographic colonography (CTC), also known as virtual colonoscopy, is an
emerging alternative technique for screening of colon cancers. CTC uses CT to provide a …

Background & AimsIn isolation, computer-aided detection (CAD) for computed tomographic
(CT) colonography is as effective as optical colonoscopy for detection of significant …

Purpose To assess the effect of using computer-aided detection (CAD) in second-read mode
on readers' accuracy in interpreting computed tomographic (CT) colonographic images …

" This book presents the technology evaluation methodology from the point of view of
radiological physics and contrasts the purely physical evaluation of image quality with the …

Purpose To quantify the changes in reader performance levels, if any, during interpretation
of computed tomographic (CT) colonographic data when a computer-aided detection (CAD) …

Purpose: To determine whether computer-aided detection (CAD) applied to computed
tomographic (CT) colonography can help improve sensitivity of polyp detection by less …

Computed tomographic colonography (CTC) is a minimally invasive technique for imaging
the entire colon. Based on a helical thin-section CT of the cleansed and air-distended colon …

Purpose: To prospectively compare the diagnostic performance and time efficiency of both
second and concurrent computer-aided detection (CAD) reading paradigms for …

A computer system that provides stereoscopic images is described. During operation, the
computer system generates the stereoscopic images at a location corresponding to a …
