一种磁共振化学位移编码成像方法、装置及设备制造方法及图纸

一种磁共振化学位移编码成像方法、装置及设备，属于磁共振成像技术领域。所述方法包括：在基于两点磁共振信号模型建立的phasor‑error谱中将具有唯一相位因子值且使该谱达到局部极小值的像素点确定为初始种子点；根据初始种子点对待估像素点的相位因子值进行估计获得场图；将场图在最高分辨率下进行映射及合并后获得重构场图；从重构场图中确定重构种子点，并通过对重构种子点进行估计以获得重构待估像素点的相位因子值；根据重构种子点和重构待估像素点的相位因子值得到两种预定成分的分离图像。所述方法将同时含有两种成分的区域识别为种子点，排除了最高分辨率下由于相位因子值跳变造成的偏差，保证最终种子点选择的正确性。

Magnetic resonance chemical shift coding imaging method, device and equipment

The invention relates to a magnetic resonance chemical shift coding imaging method, a device and a device, belonging to the technical field of magnetic resonance imaging. The method includes: the establishment of two magnetic resonance signal model of phasor error spectrum will have only phase factor value and the pixel spectrum to local minima is determined as the initial seed points based on the initial seed points to estimate; according to the phase factor pixel values are estimated to obtain field map; field map mapping and merging at the highest resolution obtained after reconstruction field map; determine the seed points from the reconstruction reconstruction field map, and through the estimate to obtain the estimated phase reconstruction pixel values on the reconstruction of the seed point; according to the reconstruction and reconstruction of seed points to be estimated phase factor pixels to be separate images of two predefined components the. The method divides the region containing two components into seed points, and eliminates the deviation caused by the jump of the phase factor value at the highest resolution so as to ensure the correctness of the final seed point selection.
