Embodiment 1
[0032] By operating the MRI scanner (1), a 50-year-old female patient is subjected to breast MRI examination, that is, the limbs to be scanned (2) are imaged and analyzed, and the high-quality medical image data of the patient's bilateral breasts (3) are obtained by scanning. figure 1 Shown.
[0033] Based on the breast medical image data obtained from MRI, use 3D image reconstruction algorithm or commercial medical image processing software, such as Mimics, to reconstruct the 3D image of breast tissue (5), measure the patient's breast and breast 3D morphology data, pay attention to tumors Five parameters for breast aesthetic evaluation on the side and non-operative side, R line, H line, QQ line, upper π line, and lower π line (6).
[0034] Using the image difference between normal breast tissue and tumor tissue, extract the tumor part by image segmentation method, clearly show the tumor boundary, and use the center of the tumor side nipple as the coordinate origin to determine the ...

Abstract
The invention discloses a breast prosthesis manufacturing method based on the three-dimensional printing technology. The method comprises the steps that a tumor to be excised is analyzed and positioned according to breast medical image data of a patient before an operation, the shape, size and position of the excision part are determined, a three-dimensional digitalization tumor model is established, the radical treatment of the tumor and the demand for individualization overall beauty of the patient in the breast reestablishing process are comprehensively taken into consideration, a breast prosthesis three-dimensional model is optimized and designed according to the established tumor model and the breast shaping golden method, biologically-compatible materials conforming to the hand touch texture of the breast are selected, and the breast prosthesis is printed and formed through the biological three-dimensional printing technology. According to the breast prosthesis manufacturing method, the relation between the breast tumor and the peripheral tissue can be clearly displayed by analyzing and establishing the three-dimensional digitalization tumor model, and thus a doctor can conveniently determine the tumor excision range before the operation; the individualized accurate breast prosthesis can be provided for the patient quickly through the biological three-dimensional printing technology to improve the tumor radical treatment effect and the plastic surgery treatment effect, the living quality is improved, and the medical cost is lowered.
Description
Technical field [0001] The invention relates to the field of medical treatment and breast prosthesis manufacturing, in particular to a breast prosthesis manufacturing method based on medical imaging and rapid prototyping technology. Background technique [0002] In recent years, the incidence of breast malignant tumors is the first among female malignant tumors in developed countries in Europe and America or in cities in my country. The current treatment for breast cancer is mainly a comprehensive treatment based on surgery. The main surgical methods include traditional modified radical mastectomy and breast-sparing radical mastectomy developed in recent years. The traditional modified radical mastectomy for breast cancer is to remove the total mastectomy, resulting in the absence of the entire breast; if the breast-sparing radical mastectomy is insufficient, the tumor will remain and the treatment will fail. If the resection is too large, the entire breast will be deformed. , L...
