[Dose reduction by several measures in X-ray angiographic system].

"The radiation protection measures from equipment side, from a maker's point of view."TAKAJI SAITO Medical Solutions Marketing Division, Siemens-Asahi Medical Technologies Ltd. Taking care of limited fluoro and acquisition time during every case is an important prerequisite for dose reduction. Latest technology provides us with a number of means for dose savings regarding patients and staff. Here, the practical techniques of the radiation control function in angiography system are addressed. Last Image Hold (LIH). Collimation without radiation on LIH. Pulsed fluoroscopy at high and low rates. Additional spectral filters in the X-ray beam. Display of applied dose during the procedure These technological measures will definitely contribute for dose reduction for interventional procedures.
