Patent Images
1. A sub-aperture transceiver system for an ultrasound probe, the system comprising:
- a signal processor;
receive signal connections coupling the signal processor to a receive aperture comprising acoustic transceiver elements;
transmit signal connections coupled to a transmit aperture comprising at least one acoustic transceiver element multiplexed with the receive aperture;
a receive aperture output driven by the signal processor for carrying a signal obtained over the receive aperture.
