ULTRASOUND SCANNING SYSTEM AND ULTRASOUND SCANNING METHOD

摘要

An ultrasound scanning system includes a probe adaptor, a plurality of channel modules and a backend controller. The probe adaptor is connected to an ultrasound probe and has a plurality of frontend channels. Each of the channel modules has an identification code and includes a switch, a transmitter, a transmitter beamformer, a receiver and a receiver beamformer, wherein the switch is coupled to the probe adaptor, the transmitter is coupled to the switch, the transmitter beamformer is coupled to the transmitter, the receiver is coupled to the switch, and the receiver beamformer is coupled to the receiver. The backend controller is coupled to the probe adaptor, the transmitter beamformer of each of the channel modules and the receiver beamformer of each of the channel modules.

1. An ultrasound scanning system comprising:
a probe adaptor connected to an ultrasound probe, the probe adaptor having a plurality of frontend channels; a plurality of channel modules, each of the channel modules having an identification code, each of the channel modules comprising:
a switch coupled to the probe adaptor;a transmitter coupled to the switch and the probe adaptor;a transmitter beamformer coupled to the transmitter;a receiver coupled to the switch; anda receiver beamformer coupled to the receiver; a backend controller coupled to the probe adaptor, the transmitter beamformer of each of the channel modules and the receiver beamformer of each of the channel modules, the backend controller comprising a demodulator; wherein the backend controller transmits a transmitter beamforming information to the transmitter beamformer of each of the channel modules, each of the transmitter beamformers converts apart of the transmitter beamforming information into a plurality of transmitter beamforming signals according to the identification code correspondingly, each of the transmitters transmits the transmitter beamforming signals to the probe adaptor, the transmitter beamforming signals drive the ultrasound probe to emit a plurality of ultrasound signals through the frontend channels, each of the receivers receives a plurality of reflected signals of the ultrasound signals through the ultrasound probe and the probe adaptor, each of the receiver beamformers converts the reflected signals into a plurality of receiver beamforming signals, the backend controller merges the receiver beamforming signals generated by each of the channel modules into a scanning line signal according to the identification codes, and the demodulator divides the scanning line signal into an in-phase signal and a quadrature-phase signal.
