Abstract
Official abstract text for this publication.
A transmit/receive isolation for an ultrasound system to block a high voltage transmit signal from being propagated to a receiving unit during a transmission period of an ultrasound signal is disclosed. An ultrasound system includes a switching unit coupled to a transmitting unit, a ultrasound probe and a receiving unit. The switching unit includes diode bridges and a switching module having pairs of switches connected to the respective diode bridges, wherein each pair of switches is configured to perform switching between a plus voltage and a minus voltage to forward-bias a corresponding diode bridge to allow a respective receive signal to be propagated to the receiving unit in a first state and to reverse-bias the corresponding diode bridge to block a respective transmit signal to be propagated to the receiving unit in a second state.
First claim
Opening claim text (preview).
What is claimed is: 1. An ultrasound system, comprising: a transmitting unit configured to form a transmit signal; an ultrasound probe comprising a plurality of transducer elements and configured to receive the transmit signal from the transmitting unit, convert the transmit signal into an ultrasound signal, transmit the ultrasound signal to a target object, receive a respective echo signal from the target object in each of the plurality of transducer elements, and form a respec…
