Medical imaging processing and analysis methods have significantly improved during recent years and are now being increasingly used in clinical applications. Preprocessing algorithms are used to influence image contrast and noise. Three-dimensional visualization techniques including volume rendering and virtual ...

Image quality, metal artifacts, and diagnostic confidence in bone, pelvic organs, and soft tissue adjacent to the prosthesis were jointly scored by two experienced musculoskeletal radiologists. Contrast-to-noise ratios (CNR) between bladder and fat and muscle and fat were measured. Wilcoxon signed-...
Aim: To find a more efficient and accurate method for medical image enhancement to resolve the problem of low local contrast, which often appears in magnetic resonance (MR) images. Methods: Based on the investigation into the previous methods, a new algorithm was presented. The main features we...
In contrast, the second fully connected layer was built upon the feature representation generated by the first layer, which was used to extract more high-level and complex features. These feature representations of coal data points tended to display greater diversity and variation, resulting in a ...
The future of image perception in radiology: synergy between humans and computers. Diuretic contrast-enhanced magnetic resonance urography (MRU) is analogous to conventional intravenous urography (IVU) and, hence, designated as excretory ... EA Krupinski - 《Academic Radiology》 被引量: 61发表: 2003...
