Approach Considerations

Head CT Scanning

The patient is asked to lie on his or her back on a movable table that slides into and out of the doughnut hole. An x-ray tube typically rotates around the patient's head.

The table will gradually move during the CT data acquisition.

The CT technologists, using a special computer workstation, process the imaging data, which are then sent to a Picture Archiving and Communication System (PACS) for a trained radiologist to interpret the images.
