Philips X5-1 Matrix Array

G. Wayne Moore, B.Sc., MBA, FASE

The X5-1 2D-matrix array transducer is primarily used in adult echocardiography. The array is made up of 128 sub-arrays configured in 16 rows and 8 columns and has a total of 3,040 elements. An applications specific integrated circuit (ASIC) located in the nose cone and attached to the acoustic stack is the engine that drives the array. This ASIC receives and transmits control and data signals to and from the system mainframe. The patented Acertara ATLAS system shown below was developed to “speak to” the ASIC and allow individually testing and reporting on each of the sub-arrays performance (see accompanying graphs). It took a great deal of engineering know-how to reverse engineer this ASIC, but that is what we do – lead. Since the year 2000 the Acertara R&D team has pioneered the development of probe testing devices that match the sophisticated technology found in ever increasing technologically complex probes. FirstCall was the first probe test device our team developed twenty years ago and now ATLAS has become the industry gold standard being used by OEMs and various research facilities around the world. It is also the device we use to test probes sent to Acertara for repair. Along with the X5-1 ATLAS also tests the Philips X7-2t, and soon the X6-1.
