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.

Intrinsic Characteristics Measurement 

Comprehensive analysis of the internal sensors and components

  • X (f) Normalized Loop Frequency Response
  • X (t) Normalized Loop Time Response
  • S-Loop (f) Wideband Loop Sensitivity
  • B (t) Optimum Drive Waveform Signal
  • S-LC Characteristic Loop Sensitivity

Probe Lens Focusing

Creation of a complete focus diagram

  • Measurement of the characteristic loop sensitivity along the axial distance
  • Measurement of height focus and divergence of the ultrasonic beam through the acoustic membrane

Echo Measurement 

Variable echo signal analysis

  • B (t) Reference drive signal
  • V e (t) Echo signal
  • IG e Insertion gain of echo
  • RE e (f) Relative energy spectrum of echo

Failure analysis on ultrasound probes

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 in good 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.
