Analysis & Documentation

Technical documentation

Comprehensive entry and outgoing analysis of ultrasound probes – Certified according to ISO 13485

Failure analysis on ultrasound probes / transducer

The probe analysis at ORTNER includes a wide range of test and analysis procedures. In this way, hidden defects on the transducer can be discovered on time before they lead to a loss of quality or a total failure.

A comprehensive analysis and complete documentation is the basis for our ISO 13485-certified repair of your ultrasound probe.

Advanced Probe Performance Measurement – APPM


Capacitance Measurement 

Status analysis of the sensors

An ultrasound probe consists of many individual elements, coaxial cables and power electronics. During the capacitance measurement, the total static capacitance is measured, which provides information about the aging and condition of the probe.

Transmission Crosstalk Measurement 

The transmission crosstalk with Optimal Drive Waveform signal is defined and measured

This measuring method can be used to identify possible damage to the mechanical structure of the piezocrystals. For example, oxidation damage in the probe can be detected at an early stage.
