Ensuring clinical efficacy and patient safety with repaired ultrasound probes

Overview This special communication highlights the potential electrical, heating and clinical risk caused by repairs carried out on ultrasound probes by manufacturers who are not the original equipment manufacturer (OEM). Such manufacturers are not regulated by the FDA and thus can result in ‘repaired’ probes with significant electrical, acoustic or heating defects.  Three recommendations are made by the authors: (1) All ultrasound probe repair manufacturers should be held to the same regulatory and compliance standards as OEMs. (2) When selecting or replacing probes, clinics should select a quality vendor (ISO certified). (3) Clinics should track performance of probes by regular scanning of a tissue mimicking phantom target.
