Course Description

Builds on information from previous radiation physics courses in the series. Introduces computed tomography, magnetic resonance, nuclear medicine, sonography and radiation therapy. Department permission required. Prerequisites: RAD 107.

Addendum to Course Description

This course is the third in a series of three courses in Radiological Physics. Each course builds upon information from the previous courses in the series. The student will receive instruction on advanced imaging equipment which includes computed tomography, magnetic resonance imaging, radiation therapy, nuclear medicine and ultrasound.
Physics of Advanced Imaging is required as part of the Radiologic Technology degree program. It is also a prerequisite for taking the American Registry of Radiologic Technologists examination for certification in Radiography. Transferability of credit depends entirely upon the institution to which the student wishes to transfer.

Intended Outcomes for the course

1. Communicate basic knowledge of advanced imaging technology.
2. Evaluate advanced imaging opportunities for professional growth.

Outcome Assessment Strategies

1. Develop a case study of a disease process that uses one of the advanced imaging procedures studied this term.
2. Read and summarize a professional journal article regarding an advanced imaging procedure.
3. Write a self-assessment to evaluate why and how you would progress into a particular advanced imaging field.
