血管内超声诊断设备性能测试研究

摘要

Nowadays, there is no reference criterion for testing the performance of intravascular ultrasound system (IVUS), a specialized ultrasound diagnostic equipment. Here, with reference to the National Standard of PRC GB10152-2009 for B mode ultrasonic diagnostic equipment, we investigated the testing methods of resolution and center frequency for IVUS. After the testing method was determined, a testing system was established and the test and verification were carried out for the performance indexes such as center frequency and resolution. The results provide a good technical basis to establish the standard test specifications for the manufactures of IVUS.%血管内超声成像设备是一种专用的超声检测设备,对其性能检测目前没有合适的参考标准.本文参照GB10152-2009对B型超声诊断设备的要求,对血管内超声成像系统的分辨力和中心频率两个指标参数开展研究,确定检测方法并建立测试系统,最后对中心频率及分辨力等性能指标进行了测试验证.本研究为血管内超声成像设备检测规范的建立提供了很好的基础.
