| 1. An apparatus for ultrasonic imaging, the apparatus comprising:
a chip;
a transducer array having a plurality of receive transducer elements that forms part of the chip, each receive transducer
element adapted to produce received analog ultrasonic signals on a signal line; and
a plurality of conditioning circuits adapted to provide signal conditioning to the received analog ultrasonic signals and
produce conditioned analog ultrasonic imaging data signals, each conditioning circuit forming another part of the chip, being
disposed substantially below one of the transducer elements associated therewith, including an analog sample and hold circuit,
and being coupled to one of the signal lines and one of a plurality of intermediate outputs.
