1. A multidimensional transducer array system, the system comprising:
an acoustic array having transducer elements distributed in a grid over first and second dimensions, the acoustic array having a first extent of the transducer elements along the first dimension;
a dematching layer connected with the acoustic array in an acoustic stack, the dematching layer supporting the transducer elements on a first side and extending by a second extend along the first dimension, the second extent greater than the first extent;
a chip of an application specific integrated circuit directly bonded to a second side of the dematching layer, the second side opposite the first side; and
a flexible circuit connected to the dematching layer on the first side.
