Acertara Acoustic Laboratories, Longmont, Co, announced that it is providing calibration and repair services for the FirstCall ultrasound probe tester and the FirstCall probe adaptors from Unisyn.

First Call is used to test the acoustic and electrical properties of an ultrasound probe. By independently exciting each crystal within the array of the probe, FirstCall can measure the relative sensitivity of each element and analyze the acoustic signature of the returning pulse for any variations in key performance parameters. FirstCall tests most electronic array probes produced by Acuson, Siemens, Aloka, ATL/Philips, Agilent/Philips, Esaote/Biosound, GE, Medison, Sonosite, Toshiba, and others.

Acertara is an independent, ISO/IEC 17025:2005-accredited medical ultrasound acoustic measurement and testing laboratory.
