摘要
数字化血管造影系统的主体是数字减影血管造影(DSA)设备,主要用于血管造影和介入放射学。当前,随着DSA设备的成像质量改善,其输出量也越来越大,这增加了操作者和患者辐射损伤的可能。剂量优化就是研究成像质量和照射剂量间的关系,在充分保证成像质量的同时合理降低照射剂量。
Digital angiography system is mainly composed of Digital Subtraction Angiography （DSA）equipment and mostly used in angiography and interventional radiology. With the improvement of image quality, modern DSA equipment has a higher radiation output capacity, which increases the potential radiation damage to the operators and patients. Dose optimization studies the relationship between image quality and radiation dose for reasonable reduction of radiation dose and good image quality.
