Abstract:
The ultrasound probe is the most important accessory in ultrasound equipment,which adopted the piezoelectric vibrator as its core component,and it can complete ultrasonic emission and receiving echoes.A deep understanding for the operational characteristics of the probe's array elements is important premise that user can accurately judge the running situation of the probe.This study employed pulse-echo technique to detect sensitivity and capacitance of the array elements of ultrasonic probe.The detected data of 60 probes at China-Japan Friendship Hospital were collected,and 75%of the 60 probes existed residual couplant,and 80%of them existed indentation or damage to the outer skin.The tested results of leakage current indicated that 1 probe(1.7%)existed excessively high leakage current.In test for array elements,2 probes(3.4%)displayed partial damage at array elements,and 6 probes(10.2%)were irreparably damaged.The preventive test for the diagnostic equipment with ultrasound is helpful to establish a quality control system for ultrasound,and to provide analysis materials with reliability in using diagnostic equipment with ultrasound,and to also provide decision-making basis for equipment departments and clinical department of using equipment in hospital.
