This course is the study of the analyzation of radiographic images, and the quality control for radiographic equipment. It places focus on the critical thinking skills required to analyze healthy and diseased images and make the appropriate adjustments as necessary. Topics covered will include image criteria, diseases, and quality control equipment tests. This course will prepare students for critiquing images, identifying diseases, and quality control testing.
Prerequisite: RTE2000
RTE2200 Radiobiology and Radiation Protection
50 hours, 4 credits
RTE2200 Lecture (30 hours, 3 credits)
RTE2200 Lab (20 hours, 1 credit)
This course is the study of the effects of radiation on the human body and how to minimize exposure through radiation protection. It will focus on implementing the ALARA principle in order to safely use diagnostic radiation in the medical field. It will cover short- and long-term effects of radiation and protection measures used in clinical settings. This course will prepare students to go into an externship with a solid foundation of ionizing radiation interactions with biologic systems.
Prerequisite: RTE2000
