Computed Tomography Technologist

About the Profession

Computed tomography (CT) technologists are medical imaging professionals who use specialized equipment to produce cross-sectional images of human anatomy. One of several modalities situated within the larger field of radiology, CT uses X-rays and computer technology to create detailed images of internal organs and tissues. Physicians and healthcare personnel rely on CT to aid in the diagnosis of medical issues. CT technologists apply their knowledge of anatomy, pathophysiology, physics, instrumentation, and radiation safety in their daily practice to provide quality diagnostic imaging and patient care. These professionals are employed in various medical facilities including hospitals, clinics, labs, and outpatient centers.

About the Program

The CT Program at Vanderbilt University Medical Center (VUMC) provides asynchronous online coursework and in-person clinical training for prospective CT technologists. Coursework focuses on clinical procedures, patient care and safety, anatomy and physiology, and physics and instrumentation. Clinical rotations take place at numerous sites on the VUMC campus. Rotations also occur in locations off the main campus, including sites such as One Hundred Oaks, Hillsboro Imaging, Williamson Imaging (Cool Springs), Vanderbilt Health Hendersonville, and regional hospitals in Wilson County (Lebanon), Bedford County (Shelbyville), and Coffee County (Tullahoma). The CT Program also provides students a comprehensive overview prior to sitting for their national board certification exams. Graduates are eligible to sit for board exams specializing in CT including the American Registry of Radiologic Technologists (ARRT)(CT) and the Nuclear Medicine Technology Certification Board (NMTCB)(CT).

  • Timeline: 3-6 months
  • Cohorts: 2 per year
  • Cohort Size: 15 students

Online coursework enables working professionals to fit CT education around their own schedules. Though students are expected to adhere to a pre-established timeline, much of the coursework is self-paced. Clinical rotation shifts are coordinated between the CT Program and VUMC Radiology. Students will complete an average minimum of 12 hours in CT clinical rotations per week totaling at least 300 hours by program completion. During imaging rotations, each student is designated to a single, independent work assignment supervised by a board-certified technologist. Proficiency in clinical competencies is required during rotations.
