Routine probe testing can reveal probe degradation that is not immediately apparent to the Sonographer or Service Engineer. Our experience has shown that approximately 25% of all probes on ultrasound systems aged 2 years or over, have some form of internal structural defect. Probe testing and analysis is a three step process that will uncover any degradation that has occurred within the entire structure of the transducer. Digital Analysis A quantitative interrogation of the transducer’s electrical and acoustic properties is carried out on Probelogic’s Digital Analyser. Microscopy Every transducer is carefully inspected under a high powered microscope for surface imperfections and perforations. Electrical Safety Testing All transducers are electrically safety tested to ensure safe operation. This is paramount for all intracavitary probes.http://www.probelogic.com.au/service/ultrasound-probe-testing/
