Abstract: An ultrasonic imaging system and an ultrasonic imaging method are provided. The ultrasonic imaging system includes a transmitting beamformer, a receiving beamformer, transducer elements and a controller unit. In a transmitting process, the controller circuit controls the transmitting beamformer to transmit ultrasonic sound signals. In a receiving process, echo signals are received at the transducer elements, the controller unit applies a common fine delay set to the echo signals by controlling a common fine delay beamformer of the receiving beamformer, the delayed echo signals are summed to generate first summation signals, the controller unit further applies compensated coarse delay sets to the first summation signals by controlling coarse delay beamformers of the receiving beamformer, and the delayed first summation signals are summed to generate output beam signals.

Abstract: The ultrasonic system of the present invention uses a microwave beamforming architecture, which can disassemble the multi-channel delay circuit into two circuits of fine delay and coarse delay. Through multi-stage input signal delay and summation, the signal at the probe end can be effectively reduced. The amount of data and hardware complexity meets the needs of system miniaturization. Moreover, the present invention only uses a single microwave beamformer to realize the fine delay calculation of beamforming, and cooperates with the multi-line coarse delay beamforming operation to meet the requirements of multi-line imaging; the setting values of fine delay and coarse delay are also compensated and correction to maintain the accuracy required for multi-line beam focusing on the delay time of each channel.

Abstract: A method for determining whether an ultrasound probe is on a scan state or on a non-scan state includes the following steps. An object is scanned to generate an image by the ultrasound probe, and the image is divided into a strong echo area and a weak echo area. The ultrasound probe is determined to be on the scan state as a signal intensity in the weak echo area of the image is greater than a threshold. Otherwise, the ultrasound probe is determined to be on the non-scan state as the signal intensity in the weak echo area of the image is less than the threshold, and the ultrasound probe enters a freeze mode so as to store a frozen image at a time before entering the freeze mode.
