Abstract

Highlights: A TLD-100 dosimetry protocol was optimized for use on a mammographic phantom (M3D). Tube output, HVL and MGD accurately determined with few exposures of the M3D. Use of M3D phantom resulted in significant time savings in dosimetric QC tests. A "compact" mammography QC procedure (including M3D) was proposed. Results could ease the adoption, in some facilities, of a QC culture in mammography.
