The certificate of Computed Tomography is awarded upon the successful completion of the program.

The Computed Tomography program integrates scientific concepts and working skills through intensive clinical experience and classroom study. The program requires 3 semesters/12 months of study. The CT technologist specializes in the medical application of CT imaging techniques and equipment used in screening, diagnosis, and treatment. Graduates are eligible to apply for the post-primary pathway and sit for the CT certification examination conducted by the American Registry of Radiologic Technologists (ARRT). Graduates find employment in hospitals and private clinics.

Program Comments

  1. Prior to the start of clinical Computed Tomography courses, students are required to have on file in the Health Services Office (603) 230-4043 documentation of: current medical insurance; a complete physical examination; current immunizations; current CPR certification for one and two-person adult, infant and child. Professional liability malpractice insurance is arranged by the College and will automatically be charged to the student’s account.
  2. The Computed Tomography Program integrates all theory coursework with clinical experience. All Computed Tomography Program courses must be passed with a “C“ or above before proceeding to the next level.

Academic and Clinic Schedules

Every attempt is made to optimize classroom schedules; however, we cannot always create the optimal schedule for everyone. Students accepted into the program are expected to make their education their number one priority; please plan to organize work schedules and personal commitments around the academic and clinical obligations.

Please note that the weekly schedule listed below is subject to change at any time. Clinical start times may vary based on the clinical site, but generally run 8:00 am-4:00 pm.

Summer semester: Class on Monday and Wednesday evenings; no clinical rotation.
Fall semester: Class on Monday evening; clinic on Tuesday, and Thursday.
Spring semester: Class on Monday and Wednesday evenings; clinic on Tuesday, and Thursday.

We currently affiliated with many hospitals in New Hampshire and Vermont. Students are assigned to one clinical facility. We are currently affiliated with the following sites. *Pending the addition of 5 more sites.  One student will be assigned per hospital.

Selection is determined by a cumulative point system that is based on college courses and grades and a personal interview.  Radiography and Radiation Therapy programs are offered at NHTI.

Internship Considerations

NHTI has developed excellent practicum opportunities for our students to foster hands-on learning while simultaneously receiving credit. Nonetheless, the college’s first priority must be to ensure that patients/clients/children/families are not placed in jeopardy by students during learning experiences. Therefore, students in internship, externship, practicum, service learning, and clinical experiences must demonstrate sufficient emotional stability to withstand the stresses, uncertainties and changing circumstances that characterize patient/client/child/family responsibilities. Furthermore, the student is expected to have the emotional stability required to exercise sound judgment, accept direction and guidance from a supervisor or faculty member, and establish rapport and maintain sensitive interpersonal relationships and confidentiality with employees, customers, and/or patients/clients/children and their families.
