Room 207

The American Association of Physicists in Medicine (AAPM) has adopted “innovation” and “education” among its focus areas for achieving its overall mission of “advancing medicine through excellence in the science, education and professional practice of medical physics”. The formation of task groups, established underneath the guidance of a AAPM working group or subcommittee, is one means by which these aims are pursued.

This session will open with a brief overview of the charge, structure, and current activities of the AAPM Radiography and Fluoroscopy Subcommittee, aimed at familiarizing interested physicists with the ways in which they can become more involved.

This will be followed by three talks introducing the key findings and recommendations of recent task groups dedicated to addressing specific clinical problems or practices in the field of fluoroscopy:

•"Task Group No. 272 - Comprehensive Acceptance Testing and Evaluation of Fluoroscopy Imaging Systems" (TG-272) was written based on the cardiovascular angiography system, but presents modified methodologies designed to encompass most fluoroscopy systems including conventional fluoroscopy systems, mobile C-arm equipment, and O-arm fluoroscopy units
•"Task Group No. 251 – Survey of Pediatric Fluoroscopic Exposure Rates" (TG-251) used a standardized measurement protocol to collect fluoroscopic and fluorographic air Kerma rates (AKR) as a function of simulated patient thickness, from infants to adult sized patients. While the AKR for fluoroscopes in dedicated pediatric hospitals was less than that of adult hospitals, considerable room for improvement remains in both pediatric and adult facilities
•"Task Group No. 357 – Estimating Patient Skin Dose with Fluoroscopic Procedures" (TG-357) reviews current methods and approaches for estimating the peak skin dose, with an emphasis on how DICOM information can be incorporated to improve these estimates.

Learning objectives:
1.To provide an overview of the current activities of the AAPM Radiography and Fluoroscopy Subcommittee
2.To present the comprehensive acceptance testing procedures recommended by TG-272 for fluoroscopic imaging equipment
3.To disseminate state-of-the-practice air Kerma rates collected by TG-251 to enable QMPs to evaluate their measured performance in the field of fluoroscopes for all sized patients and identify units that may not be performing well during the imaging of children in addition to adults, improving patient care for patients of all ages.
4.To provide a comprehensive review of methods for estimating patient skin dose for fluoroscopic procedures, as discussed in TG-357, and to suggest ways to improve estimation accuracy
