[Evaluation of patient absorbed dose management system in percutaneous coronary intervention].
The angiography equipment Infinix Celeve of Toshiba Corp. is a system that estimates patient absorbed dose at the skin by using a dose area product meter. This system performs incidence area compensation, which corresponds to the changes of I.I. size, FID, and FTD. We evaluated the clinical usefulness of patient entrance skin dose management by the dose area product meter of Celeve by verifying the effects of various clinical parameters on absorbed dose. We determined compensation according to the various angles usually used by clinicians, and estimated the absorbed peak dose at the skin. By using the angle compensation of the C arm, the displayed values on the dose area product meter of Celeve could be used for skin doses as they were. The skin absorbed dose was 3.0 Gy or more in 33 of the 332 examples.
