CRT-500.11 The Contribution of X-Ray Tube Housing Leak to Radiation Exposure in the Cath Lab

It has been assumed that the vast majority of the x-ray exposure to the cardiac cath lab heart team originates from scatter radiation (SR) from the patient and that x-ray leakage from the x-ray tube housing (XRT) is negligible. We investigated radiation leakage directly from the XRT and its
