Patent ID: 7348713

Claim:
An ultrasonic probe, comprising: a first two-dimensional XY array including a first plurality of rows, each row of the first two-dimensional XY array including a plurality of transducers; and a second two-dimensional XY array including a second plurality of rows, each row of the second two-dimensional XY array including a plurality of backing members arranged to mechanically support the plurality of transducers and to absorb an ultrasonic wave transmitted through the plurality of transducers, wherein said second two-dimensional XY array includes a plurality of heat conductive sheets, each of said plurality of heat conductive sheets sandwiched between two rows of backing members, and having a heat conductivity higher than a heat conductivity of the backing members, wherein the heat conductive sheets have side surfaces exposed from between the backing members; further comprising at least one heat dissipation sheet connected on a side surface of the heat conductive sheet.
