Abstract
Switching is provided in a transducer array of medical diagnostic ultrasound imaging. The switching controls the formation of macro elements or aperture for scanning a plane or volume. The switches are implemented with one or more transistors. The control causes the gates of the transistor to float during the 'on' connection. While on, the switch connects, allowing ultrasound signals to pass through the switch.
