Volume rendering with color coding of tagged stool during endoluminal fly-through CT colonography: effect on reading efficiency.

abstract：:Quantitative microstructural sonography differs from conventional sonography in several ways. The frequency as well as the amplitude of echoes is recorded and assessed using spectral analysis techniques. The effects of diffraction of the ultrasound beam are calibrated, as are the transfer characteristics of the system...
