Technical Note: Assessment of scatter originating from the x‐ray tube collimator assembly of modern angiography systems

Purpose While scatter from the patient is assumed to be the primary source of occupational radiation dose associated with fluoroscopically guided interventional procedures, the potential contribution of scatter from the x‐ray collimator assembly is unknown. The purpose of this work was to survey clinical x‐ray angiography systems to assess the potential contribution of collimator assembly scatter on occupational radiation dose. Methods...
