Problems solved by technology

These two scanning methods are relatively common, but there is no detailed description of the emission scanning sequence of the B pulse and the C pulse, and it does not involve how to improve the temporal matching of each image in the BCD three-function mode
In the actual human body imaging, the human body tissue is constantly moving, and when three different types of imaging are performed simultaneously and in real time, if the time interval for transmitting and scanning the same position with different types of pulses is too long, it may cause serious problems between images. Dislocation phenomenon, image quality deterioration

Embodiment 1

[0025] Embodiment 1: On the basis of the above technical solution, after completing the C-line scan insertion of a data packet, insert the B-line scan. This can more effectively shorten the interval time between images obtained by each type of pulse scanning. For details, please refer to image 3 and Figure 4 instruction of. Inserting the B-line scan after completing the C-line scan insertion of a data packet is the optimal implementation mode of the present invention.

[0026] In this embodiment, since there is a cross scan when the C pulse is emitted, if the number of cross scans is denoted as K, the number of repeated transmissions of the same scan line is denoted as P, and the C pulse emitted during the nth scan of the mth scan line is denoted by C m，n Represent, wherein m=1, 2, ... K; n = 1, 2, ... P; then the sequence of transmitting C pulses in a Packet (data packet) is:

[0027] C 1，1 , C 2，1 ...C K，1 , C 1，2 , C 2，2 ...C K，2 ,...,C 1，P , C 2，P ...C K，P ...

Embodiment 2

[0029] Example 2: see image 3 , on the basis of Embodiment 1, the time interval of the above-mentioned D-line scanning includes: several first time intervals, which are equal to the interval PRI between two adjacent emission D pulses D . image 3 The C / B pulse emission scan sequence is given. in several PRIs D Insert a Packet (data packet) C-line scan in the interval, and then immediately, in several PRI DThe B-line scan corresponding to the above-mentioned one Packet (data packet) C-line scan is inserted in the interval. Since Color imaging is a C-line scan, there is a cross-scan, and the ultrasound system calculates the number K of cross-scans according to the parameters selected by the user, and K is the number of C-line scans inserted in the first time interval.

[0030] Based on the sampling line selected by the user, the D-line emission scan corresponding to the sampling line is determined. for example image 3 , the ultrasound system uses PRI for the sampling lin...

Embodiment 3

[0032] Embodiment 3: see Figure 4 , on the basis of Embodiment 1, the time interval of the above-mentioned D-line scan data includes: a second time interval, which is equal to the scanning interval of two adjacent continuous emission D pulses, assuming that the time of continuous emission D pulse is T D , then two adjacent T D is the second time interval. Figure 4 The C / B pulse emission scan sequence is given. The ultrasound system determines the continuous emission scan time T of the B line according to the parameters selected by the user B , the continuous emission scan time T of line C C , the continuous emission scan time T of line D D . Among them, T C It is the time to scan a Packet C line. The ultrasound system determines T from user-selected parameters B The number of inserted B lines.

[0033] Because there are cross-scans in Color imaging, the ultrasound system calculates the number K of cross-scans according to the parameters selected by the user. The em...

Abstract

The invention discloses an imaging method and an imaging device in a three-function mode in an ultrasonic system. The method comprises the following steps: inserting C line scanning utilizing C pulses within a time interval of D line scanning; and inserting corresponding B line scanning utilizing B pulses in a C line scanning position area within a time interval of the next D line scanning adjacent to the C line scanning. In the imaging method, an emission scanning sequence during the imaging of an ultrasonic imaging system in a BCD three-function mode is defined in a mode of inserting the C line scanning among gaps of the D line scanning first and then inserting the B line scanning corresponding to the C line scanning; and in addition, after the C line scanning is inserted, the B line scanning corresponding to the C line scanning is inserted immediately, so that the time interval of time-share scanning of pulses with different types at the same position, and thus the serious malposition phenomenon generated among various types of images can be avoided, and the time matching degree of various types of images and the imaging quality are improved.

Description

technical field [0001] The invention relates to the technical field of multifunctional imaging in an ultrasonic imaging system, in particular to an imaging method and device thereof in the three-function mode of an ultrasonic system that can improve the time matching degree of each image during multifunctional imaging. Background technique [0002] There are several imaging modes in the ultrasound imaging system, for example, black and white imaging mode (also called B mode, corresponding to B image), color blood flow imaging mode (also called Color mode, corresponding to Color image), pulse Doppler mode (also called Called PW mode, corresponding to Doppler spectrum image) and so on. Different types of imaging correspond to different types of pulses, black-and-white imaging corresponds to B pulses, color blood flow imaging corresponds to C pulses, and Doppler spectrum imaging corresponds to D pulses. In B mode, the system only emits B pulses, and uses grayscale to represent...
