适用于产生单一连续波或准连续波超声波束的探测器。它不包括连续监测设备,这些设备会产生一个以上的超声波束,并使用捆绑在患者身上的扁平标准探头。本标准不是设备设计标准。交叉引用:BS 5724:第1BS 7041BS EN 61101BS EN 61102BS EN 61157BS EN 61161IEC 854部分
Applies to detectors which generate a single continuous wave or quasi-continuous wave ultrasonic beam. It does not cover continuous monitoring devices which generate more than one ultrasound beam and use a flat standard probe strapped to a patient. This standard is not an equipment design standard.Cross References:BS 5724:Part 1BS 7041BS EN 61101BS EN 61102BS EN 61157BS EN 61161IEC 854
