Half A Century In CT: How Computed Tomography Has Evolved
These CT scanners have a gantry that rotates continuously in the same direction. During scanning, data acquisition is combined with continuous movement of the patient through the gantry. The path of the X-rays can be described as a spiral or helix, hence the name helical or spiral CT. Meer weergeven The scan itself takes only 10 to 15 minutes or less.
