Abstract
An ultrasound probe is tested for failure of 5 elements of its array transducer by operating the probe with its lens in contact with the air. The echo signals produced during this mode of operation are beamformed into the usual set of scanlines produced by the probe. The frequency response of 10 each scanline is analyzed and compared with a reference signal of the frequency response of the corresponding scanline of a known good probe of the same type as the probe under test. If a comparison reveals a variance greater than a predetermined 15 deviation, the user is alerted that the probe should be replaced.
