Abstract
This invention is provided a method for making a backing layer for an ultrasonic matrix array transducer useful in diagnostic imaging, non-destructive material testing and treatment of human organs. The method includes placing the grid in a mold, filling the mold with an acoustically absorbent material such that the absorbent material fills the spaces between the contacts, curing the material in the mold so as to form a block formed by the cured absorbent material and the grid, and releasing the block from the mold.
