Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0042] The system block diagram of simultaneous display of ultrasonic Doppler spectrum image and color blood flow image according to the present invention, such as figure 1 shown. The ultrasound system is in the state of simplex transmission. By applying this system, duplex display in simplex mode can be realized, that is, Doppler images and color blood flow images can be obtained and displayed at the same time only by emitting Doppler scanning pulses. The system includes a Doppler pulse generating module, a transmitting and receiving module, an ultrasonic transducer, a time gain compensation amplifier, a beam forming module, a Doppler signal processing module, a color blood flow signal processing module and a display module.

Abstract

The invention discloses a method and system for simultaneously displaying a Doppler image, a B-type image and a colored blood flow image. The method comprises the steps of: sending B-type scanning pulses and Doppler scanning pulses at an interval according to a time sequence; receiving ultrasonic echoes of the scanning pulses and converting into electric signals; carrying out B-type signal beam synthesis on B-type ultrasonic echoes, and carrying out Doppler signal beam synthesis on Doppler ultrasonic echoes; transmitting the signal obtained after the B-type signal beam synthesis to a B-type signal processing module to obtain B-type image data; dividing the signal obtained after the Doppler signal beam synthesis into two parts, carrying out Doppler signal processing on one part to obtain Doppler frequency spectrum data, and carrying out colored blood flow signal processing on the other part to obtain colored blood flow image data; and transmitting the B-type image data, Doppler frequency spectrum data and colored blood flow image data to a display module for synchronously displaying. The method and system disclosed by the invention have the advantages that: Doppler, B-type and colored blood flow images can be simultaneously displayed under the condition of not increasing extra emission.

Description

technical field [0001] The present invention relates to the field of ultrasound imaging in a medical ultrasound system, in particular to a method and system for simultaneously displaying a Doppler image and a color blood flow image in an ultrasound imaging system, as well as a Doppler image, a B-mode image and a color flow image. Method and system for simultaneously displaying blood flow images. Background technique [0002] The pulsed wave Doppler image is to transmit ultrasonic pulse signals into the target tissue of the human body at regular intervals through the ultrasonic front end, detect its Doppler frequency shift information, and obtain its spectrum or power spectrum in real time, after specific processing, it is finally displayed as Doppler A spectrogram, which contains information related to the velocity of tissue movement or blood flow. [0003] The color blood flow image calculates the dynamic information of the blood cells in the blood flow through the moving ...
