Embodiment Construction

[0017] Such as figure 1 Shown is a method for preparing a novel 3D precise breast and chest wall conformer, which is characterized in that:

[0018] Step 1: Use a portable 3D laser scanner to perform positioning scans on the patient's breast, chest wall and other tissues and organs, and obtain positioning scan images.

[0019] In step 2, data processing is performed on the positioning scanning image by a computer to establish three-dimensional mold data of the individualized 3D printing conformer.

[0020] Step 3, according to the data of the three-dimensional mold, the mold of the conformal device is made by a 3D printer.

[0021] Step 4, the polymer material is poured into the mold of the conformer to manufacture the conformer.

[0022] In the first step, the sampling points of the patient's body surface are obtained by the portable 3D laser scanner, and the positioning scan image is constructed.

[0023] In the second step, the computer generates the three-dimensional mo...

Abstract

The invention provides a novel preparation method of a 3D accurate mammary gland and chest wall conformer. The method is characterized in that a portable 3D laser scanner is used for performing positioned scanning on the mammary gland, chest wall and other tissue and organs of a patient, a positioned scanning image is obtained, data processing is performed on the positioned scanning image througha computer, a three-dimensional mold of an individualized 3D printing conformer is established, according to data of the three-dimensional mold, a mold of the conformer is made through a 3D printer, and a mold of the conformer is filled with a high molecular material to be made into the conformer. The conformer has the advantages that when radiation therapy is performed on the patient, the dose distribution shape of an irradiation field is consistent with the shape of a target area, so that the dose of each point in the whole target area is consistent with the dose at the surface of a lesion everywhere.

Description

technical field [0001] The invention relates to a preparation method of a novel 3D precise breast and chest wall conformer. Background technique [0002] Clinically, radiotherapy for the whole breast, chest wall, upper and lower collarbone, and axillary area after breast-conserving surgery for early and middle-stage breast cancer and radical mastectomy for middle- and late-stage breast cancer must meet two conditions. First, the dose distribution shape of the irradiation field must be It is consistent with the shape of the entire target area. Second, the dose of each point in the overall radiotherapy area is consistent with the dose of the patient's lesion body surface. However, at present, square-shaped tissue-equivalent materials of different sizes are commonly used in clinical practice. The defect is that the tissue Poor uniformity, low degree of individualization, inability to fit tightly on uneven body surfaces, and air gaps, affecting dose distribution and accuracy of ...
