Embodiment Construction
[0065] The following describes in detail in conjunction with the embodiments and the accompanying drawings.
[0066] refer to Figure 1 to Figure 4 , a multimodal carotid MRI registration method based on physical alignment and contour matching, comprising the following steps:
[0067] 1) Calculate the spatial physical coordinates of the image: First, determine the spatial physical coordinates through the original DICOM image information to obtain the spatial information of the multimodal carotid artery MRI, and then intercept useful information according to the spatial position relationship to ensure complete and accurate images of each layer of each sequence The pixel alignment, described step 1) comprises the following process:
[0068] (1.1) Export the original data DICOM label information, first save the label information of each sequence image: row resolution Rows (m), column resolution Columns (n), layer thickness Slice Thickness (t), slice spacing Spacing BetweenSlices...
