Abstract
Dual-slice CT has been designed to achieve faster scanning. In scanners used for this type of investigation, a wide-fan X-ray beam strikes two side-by-side parallel arcs of detectors producing a double spiral of spatial information. Compared with single-slice CT, dual-slice CT makes it possible to scan the same volume in half the time with no degradation of image quality. Thus, the entire urinary tract can be imaged completely from the upper pole of the kidney to the pelvic floor in less than 25 s during a single breath-hold (30-cm spiral length, pitch 1.5, 5.5-mm slice thickness).
