First primitive ct scanner
WebModern multi-slice CT scanners can acquire up to 620 cross-sectional images at once; each rotation may be as short as ¼ second. These systems are capable of continuous rotation (helical or spiral scanning), in which motion of the patient through the scanner occurs in concert with the rotation of the scanner.
