The aim of this study was to perform a blinded trial, comparing the results of a visual inspection of the in-air reverberation pattern with the results of an electronic probe tester in detecting ultrasound probe faults. Sixty-two probes were tested. A total of 28 faults were found, 3 only by in-air reverberation assessment and 2 only by the electronic probe tester. The electronic probe tester provided additional information regarding the location of the fault in 74% of the cases in which both methods detected a fault. It is possible to detect the majority of probe faults by visual inspection and in-air reverberation assessment. The latter provides an excellent first-line test, easily performed on a daily basis by equipment users. An electronic probe tester is required if detailed evaluation of faults is necessary.
本研究的目的是进行一项双盲试验，比较在空中混响模式的视觉检查结果与电子探头测试仪在检测超声探头故障方面的结果。对62个探头进行了测试。共发现28处故障，其中仅通过空中混响评估发现3处，仅通过电子探头测试仪发现2处。在两种方法均检测到故障的情况下，电子探头测试仪在74%的病例中提供了有关故障位置的额外信息。通过视觉检查和空中混响评估可以检测出大多数探头故障。后者提供了一种出色的一线测试方法，设备使用者可轻松每日进行。如果需要对故障进行详细评估，则需要电子探头测试仪。
