Modeling and Driving 2D Arrays

Both CIVA and M2M systems handle 2D phased array probes (typically matrix or sectorial arrays). Using such probes, it is possible to focus the acoustic beam at any location in the specimen under investigation. The illustrated example (Fig. 1) shows the behavior of a 64 elements sectorial array @ 5MHz (manufactured by Imasonic) in an aluminum sample. Red bars represent the delay laws calculated using CIVA applied to the probe to obtain the associated focal spots (red dots at the beginning of the animation file).
Image shows a radiated acoustic beam using a sectorial probe. 64 elements are used to compute the delay laws and the acoustic field. The beam can be focused at any location in the specimen.
