WebMultidetector Spiral CT. MDCT scanners, also known as multidetector row CT, have multiple parallel rows of x‐ray detectors (currently, 4, 8, 16, or 64 for different machines). Each of the rows records data independently as the gantry rotates; consequently, a much larger patient volume is imaged with each rotation. X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source. A visual representation of the raw data obtained is called a sinogram, yet it is not sufficient for interpretation. Once the scan data has been acquired, the dat… smart board 11
