[specific embodiment]
In order to solve the problem that to carry out effective visual understanding to the propagation condition in the three dimensions of shearing wave, a kind of magnetic resonance elastography three-dimensional visualization method of three-dimensional visualization has been proposed.
Gain knowledge according to nuclear magnetic resonance image, the minimum unit in the imaging space is a pixel, and imaging space is divided into sagittal plain direction, cross-section position direction and three directions of crown position direction usually according to imaging object.Vertical each other in twos between sagittal plain direction, cross-section position direction and the crown position direction.
Magnetic resonance elastography three-dimensional visualization method as shown in Figure 1 may further comprise the steps:
Step S10 encourages imaging object, on three orthogonal directions, applies the line scanning of going forward side by side of responsive gradient, obtains the initial phase view data of imaging object on three orthogonal directions.
Apply shearing wave on the imaging object surface it is encouraged, excitation makes the particle on the imaging object displacement occur.Select three orthogonal directions to apply responsive gradient, imaging object is scanned, can collect respective direction fluctuating picture data, scanning promptly obtains the initial phase view data of imaging object on three orthogonal directions after accomplishing.
Step S20 changes the initial phase that encourages, and imaging object is scanned, and obtains the phase change view data of imaging object on three orthogonal directions.As shown in Figure 2, step S20 comprises:
Step S210 repeatedly changes the initial phase that encourages, and the phase contrast of the initial phase after adjacent two changes equates at interval.Specifically in the present embodiment, initial phase is 0 degree during beginning, and initial phase is changed into 90 degree, 180 degree and 270 degree respectively afterwards.

At last according to three-dimensional visualization modelling image.
In the above-mentioned magnetic resonance elastography three-dimensional visualization method; Through changing the initial phase of excitation; Obtain initial phase view data and phase change view data; The 3 d image data that promptly changes in time makes up the three-dimensional visualization model of magnetic resonance elastography, realizes the three-dimensional visualization of magnetic resonance elastography.In this three-dimensional visualization model, be axle with time, i.e. the phase change of excitation demonstration can be observed fluctuation communication process in time, is axle with the space, i.e. the direction of propagation of excitation demonstration can be observed fluctuation with spatial communication process.
It is pointed out that above-mentioned three orthogonal directions are preferably the transverse axis position of imaging object, crown position and sagittal plain direction in order to better meet the needs of magnetic resonance imaging and medical science.But above-mentioned three orthogonal directions are not limited to the transverse axis position of imaging object, crown position and sagittal plain direction, only need three directions in imaging space, vertically to get final product each other in twos, and three orthogonal directions just can satisfy the needs of three-dimensional visualization.
Because have certain displacement difference between neighbor pixel, primary shift value is less, be difficult to observe, therefore need shift value is carried out the stretching of a dimensioning, can produce " fluctuation " effect.Represent the size of motion vector mould value to make ripple effect more lively with various colors.
