CT Certificate

Computed Tomography 
CT is a sophisticated diagnostic imaging modality that captures cross sectional images of the patient. CT may evaluate many types of disease processes and injuries. CT is also used to help plan radiation therapy treatments and guide biopsies.

The CT technologist is an integral member of the healthcare team who is proficient in performing cross sectional images using sophisticated diagnostic x-ray equipment. This health care professional works closely with patients, fellow technologists, radiologists, and many other members of the health care team. The CT technologist can be employed in a number of health care settings that include trauma centers, hospitals, clinics, urgent care centers, or can be employed as a traveling technologist.
