Digital radiography, CT, PET, and MR are complicated imaging modalities which are composed of many hardware and software components. These components work together in a highly coordinated chain of events with the intent to produce high quality images. Acquisition, processing and reconstruction of data must occur in a precise way for optimum image quality to be achieved. Any error or unexpected event in the entire process can produce unwanted pixel intensities in the final images which may contribute to visible image artifacts. The diagnostic imaging physicist is uniquely qualified to investigate and contribute to resolution of image artifacts.

This course will teach the participant to identify common artifacts found clinically in digital radiography, CT, PET, and MR, to determine the causes of artifacts, and to make recommendations for how to resolve artifacts.

Learning Objectives:
1. Identify common artifacts found clinically in digital radiography, CT, PET and MR.
2. Determine causes of various clinical artifacts from digital radiography, CT, PET and MR.
3. Describe how to resolve various clinical artifacts from digital radiography, CT, PET and MR.
