RAD 261 — CT Principles I
Imparts the fundamentals of the physical principles and instrumentation utilized in computer tomography (CT). Reviews the hitstorical development and evolution of CT. Physics topics covered include CT beam attenuation, linear attenuation coefficeints, tissue characteristics and Hounsfield number application. Explains data acquisiiton and manipulation techniques, image reconstructon algorithms such as filtered back-projection. Explores CT systems and operations with full coverage of radiographic tube configuration, collimator design and functions, detector type, characteristics and functions of the CT computer and array processor. Examines CT image processing and display from data acquisition through post-processing and archiving. Explains patient factors related to other elements affecting image quality, artifact production and reduction, and image communication. Prerequisite: Admission into the Computerized Tomography (CT) program is required or consent of instructor, and prior or concurrent enrollment in RAD 238 with a grade of C or better. Corequisite: RAD 260 .
