[Multicenter Survey of Exposure Dose in Coronary Artery Angiography and IVR].

Purpose: In DRLs 2020, in addition to the fluoroscopic dose rate, air kerma at the patient entrance reference point (K) and air kerma-area product (P) by types of medical treatment and diseases were set as DRL quantity. We surveyed the current equipment setting dose at each facility and the exposure dose in clinical practice. We considered the optimal DRL classification of K and P for the next DRLs update.

[Multicenter Survey on Phantom Entrance Surface Air Kerma of Angiography and IVR in Japan].

Purpose: In DRLs 2020, the entrance surface air kerma (Ka,e) was set to 17 mGy/min as the reference dose rate in fluoroscopy. But, Ka,e in fluoroscopy for different regions and Ka,e in exposure was not set. A multicenter survey was conducted to evaluate Ka,e by each area.
