<p>A two-dimensional ultrasound camera (figure 3). An ultrasonic transducer piezo (41, 43, 45, 47, 49) is indium bump (52, 53) bonded to an integrated circuit (54). The integrated circuit (54) provides signal processing (20, 22) capabilities for a signal from each of a number of independent piezels (41, 43, 45, 47, 49). A 128 x 128 array of piezels (41, 43, 45, 47, 49) is constructed using a protective sealant cover (42) with an outer matching layer (44) and an inner matching layer (46) wherein the response of the layers (42, 44, 46, 48) are tuned to body tissue response. The array (12) provides C-scan capabilities.</p> |
