TU-D-206-00: Body Tomosynthesis.

The current use of tomosynthesis for musculo-skeletal, abdominal, and thoracic imaging will be considered in four sections: A. Current Practice (M. Bath) : The presently available systems for body tomosynthesis will be reviewed and the current diagnostic applications described. B. Image Features and artifacts (M. FLynn): The consequence of a limited angle linear acquisition scan on image features and artifacts will be explained. C. Radiation Dose (J. Sabol): The organ dose associated with common tomosynthesis protocols will be reported and compared to the dose for radiographic and computed tomography procedures. D. Acceptance testing and Quality Assurance (K. Jones): Recommended medical physics acceptance test will be described and appriate programs for quality assurance discussed.

LEARNING OBJECTIVES: 1. Learn how body tomosynthesis is currently being used in diagnostic radiology. 2. Understand how scan acquisitions can be designed to optimize image content and minimize artifacts. 3. Learn to radiation dose associated with common protocols. 4. Understand how to best evaluate a newly purchased tomosynthesis system. J. Sabol, Presenter is an employee of GE Healthcare.
