In Air Reverberation (IAR) Test is a scientifically recognized type of test that allows to verify the correct functioning of the ultrasound probe by analyzing the reverberation image produced by the probe when the silicone impedance adapter is in contact with the air (In Air Reverberation).

This type of test allows to highlight problems in the probe and can be carried out in the field (hospital, medical analysis laboratory).

The type of IAR test we have designed uses the Neuromem® neural chip which, inside the probe, processes the signals transmitted to the ultrasound apparatus, highlighting anomalies with respect to a reference model learned in the factory after the validation tests with phantom.

Each type of anomaly can be detected:

· detachment of the layers of the silicone lens

· loss of sensitivity

· breaking of ceramic elements

· disconnection of channels at the wiring level

· detachment of the silicone layers

BI2ART™can be implemented as a software inside Ultrasound Ecography Machines connected to a central database of exchangeable probes

BI2ART™ can be implemented as a HW design inside the USB or Wireless Ultrasound Probe

BI2ART™ can be implemented as an extension box for existing USB Ultrasound Probe models.

The currently developed model works with Neuromem® chip sw emulation. It can also work with Brilliant Neuromem® Dongle or can be made to host Neuromem® M2 boards.

When the button is pressed the FPGA inside the box directly analyzes the USB protocol of the probe extracting the IAR image and providing the anomaly signal as output.
