Computed Tomography

Computed Tomography (CT)

Completion of the Computed Tomography Advanced Technical Certificate provides the ARRT certified radiographer with the knowledge and clinical skills to specialize in the advanced imaging modality of computed tomography (CT, CAT scan). This certificate consists of academic and clinical courses designed to meet the eligibility requirements for the certification examination in Computed Tomography administered by the American Registry of Radiologic Technologists (ARRT).

Prospective Students:

  • Apply to the college, identifying Computed Tomography as your field of study.  
  • Provide verification of ARRT radiography certificate. This can be done 1 of 2 ways;
  1. Copy your card
  2. Go to the ARRT certification verification page: and print your verification, click on “details” before printing

Program Mission:

The Mission of the Blackhawk Technical College Computed Tomography Advanced Technical Certificate is to provide the radiographer academically and clinically to competently perform CT examinations and meet the eligibility requirements of the ARRT CT examination.

Program Outcomes:

  • Perform high-quality computed tomography examinations.
  • Critically evaluate image quality.
  • Practice radiation safety principles.
  • Provide quality patient care and evaluation.
  • Model professional and ethical behavior consistent with the A.R.R.T. Code of Ethics.
  • Apply critical thinking and problem solving skills in the practice of computed tomography.

Background Check:

In accordance with Wisconsin Caregiver Background law, applicants with criminal history may be denied placements at clinical affiliates. Additionally, criminal history may impact eligibility of the student to sit for the certification examination in Computed Tomography prepared by the American Registry of Radiologic Technologists (AART). Applicants with criminal history are advised to meet with the radiography program director prior to program entry.

Program Pre-Requisite Requirements:
  • Document current ARRT certification in radiography
  • Complete physical examination and program health requirements
  • A Caregiver Background Check is required for the clinical portion of this program.

Graduation Requirements:

  • Students must earn a passing grade (“C”; GPA 2.0) in all courses in the curriculum.
  • Students must complete clinical education requirements including competency examinations and evaluations.
  • All outstanding bills related to the student’s education must be paid in full before graduation.
  • Eligibility of students to take the ARRT examination is subject to successful completion and review by Program Faculty.
Note to Technologists Working at Healthcare Facilities Not Affiliated with the BTC CT Certificate Program:

Technologists working at healthcare facilities not affiliated with the BTC CT certificate that would like to explore performing clinical education at your place of employment should contact Joseph W. Ipsen M.Ed. RTR, Associate Dean of Allied Health at This option for clinical education will require establishment of a signed clinical education affiliation between BTC and the facility, so students are encouraged to start this process early.


15-526-150 CT Anatomy and Pathology 3 Credits
Presentation of anatomical structures as they appear in Computed Tomography (CT) images produced in axial, sagittal, coronal, and oblique sections. This course will also explore pathological conditions commonly diagnosed through the use of CT.

10-526-151 CT Procedures 3 Credits
This course provides instruction of specific computed tomographic procedures and includes content related to procedure indications and contraindications, patient preparation, orientation, contrast media usage and positioning. Information related to patient history, assessment, and education is also included. CT procedures will be taught for differentiation of specific structures, patient symptomology and pathology. CT images studied will be reviewed for quality, anatomy and pathology.

10-526-152: CT Physics and Instrumentation 3 Credits
Course Description: This course is designed to promote an understanding of the physics of computed tomography. Topics covered include the characteristics of x-radiation and CT beam attenuation, as well as data acquisition and manipulation techniques. Computed tomography systems will be explored covering topics including CT tube configuration, collimator and detector design, and characteristics and functions and the CT computer. Lastly, CT image processing and display will be examined from data acquisition through post processing, archiving and communication.

10-526-153: CT Clinical 2 Credits
Course Description: The CT clinical education course allows the student to complete the clinical experience requirements to be eligible to sit for the post-primary ARRT certification examination in Computed Tomography (CT). This course is also intended to develop competence and expertise in a variety of computed tomography procedures in the learner.
