Embodiment Construction

[0034] The device and method of the present invention will be described in further detail below in conjunction with the accompanying drawings and the embodiments shown in the accompanying drawings.

[0035] The signal processing flow of the continuous wave (CW) Doppler receiving module proposed by the present invention is shown in FIG. 1 . The multi-channel echo signals of the probe are amplified by the low-noise amplifier, and the amplified signals enter the analog beamforming unit. The analog beam forming unit performs time-delay focus accumulation on the multi-channel amplified echo signals. After beamforming, multiple echo signals are synthesized into one signal. If the CW signal is transmitted using a square wave, a low-pass filter must be added after the analog beamforming to filter out the high-order harmonics of the square wave except the fundamental frequency to output a sine wave. The filtered signal enters the quadrature demodulation module. If the transmission i...

Abstract

The present invention relates to a synthesis method of anolog wave beam in continuous wave Doppler module and its device. The described device includes a delay line LC network formed from inductor and capacitor and a resistor series-connected with the input end of the described delay line LC network for making magnitude compensation of inputted signal. The low-noise outputted multi-channel voltage signals are passed through the resistor series-connected with delay line to make signal magnitude compensation, after having been compensated said signals can be added into the LC network of delay line from different taps to make signal delay and signal accumulation, finally a wave beam synthesized signal can be outputted from output end of LC network.

Description

technical field [0001] The invention relates to a signal processing method and device in a medical ultrasonic diagnostic system, in particular to a method and a device for combining beams of continuous wave signals in the ultrasonic diagnostic system by using a reverse application delay line. The method and device of the present invention are especially suitable for ultrasonic diagnostic systems, especially portable ultrasonic diagnostic systems that require small volume, and the beam synthesis of B images of low-end ultrasonic systems can also adopt this scheme. Background technique [0002] At present, in the ultrasonic diagnostic system, the beamforming of the continuous wave Doppler receiving part has the following schemes: the scheme of quadrature demodulation and beamforming together, the scheme of digital beamforming, the scheme of multi-delay lines, and the scheme of single delay without compensation line plan, etc. [0003] Orthogonal demodulation combined with bea...
