The machine will make clicking and whirring noises as it acquires the images. The individual who will perform the study is known as a Radiologic Technologist. He or she has completed a rigorous course in Radiologic Technology and additional training in CT imaging. After explaining the exam, the technologist will position you on the table. The table will move into the open center of the donut as the x-rays are being taken. In order to obtain the best images po
