Embodiment Construction
[0053] The technical implementation process of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0054] A method for rapid prototyping of a head medical model based on 3D printing, the implementation steps of the method are as follows.
[0055] 1. Acquire images:
[0056] Acquire CT and MR images of the head of the same human body.
[0057] 2. Preprocessing MR images:
[0058]a) Normalize the MR image using reorientation and resampling algorithms to obtain an image with a size of 256×256×256;
[0059] b) Use the non-uniform gray-scale correction algorithm to perform gray-scale correction on the MR image.
[0060] 3. Rigid registration of CT images and MR images:
[0061] a) Obtain information such as CT / MR image size, resolution, origin coordinates, and grayscale;
[0062] b) Use the MR image as a reference image, use the CT image as a floating image, interpolate the CT image, adjust the resolution of t...
