Medical devices that employ ultrasound technology are widely used for diagnosis and treatment in almost all medical specialties. Because of the unique types of risk they pose to patients, ultrasonic medical devices must undergo highly specialised testing and evaluation. This will reduce potential risks from excessive or unintended ultrasound output or heating of device probes.
Many manufacturers lack the in-house expertise or capabilities to conduct this type of testing. This is where an independent third-party such as TÜV SÜD can help by providing globally trusted testing expertise.
Depending on their specific application, ultrasonic medical devices utilise high frequency sound waves to create images of internal human tissues for diagnostic purposes, or to warm tissue for therapeutic effect. In either case, safety and performance parameters of ultrasonic medical devices must be tightly controlled to avoid overheating or damaging tissue.
For these reasons, ultrasonic medical devices testing generally focuses on the control and performance accuracy of the device, to ensure the safety of their use with patients. Other testing issues include an assessment of the potential for signal distortion that can lead to measurement errors of diagnostically relevant parameters, and the accuracy of safety-related indications displayed by a device.
The complexity of ultrasound testing typically requires sophisticated measurement equipment, carefully calibrated testing devices and laboratory personnel experienced in ultrasound testing. For this reason, even the most advanced testing laboratories often require the services of an independent laboratory such as those provided by TÜV SÜD.
