Title:
THREE-DIMENSIONAL SHAPE POSITIONING METHOD AND THREE-DIMENSIONAL SHAPE DATA PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2023028110
Kind Code:
A
Abstract:
To provide a three-dimensional shape positioning method capable of accurately performing positioning between a subject in CT data and the subject in design data without depending on the shape of the subject.SOLUTION: A three-dimensional shape positioning method includes the steps of: acquiring three-dimensional CT data 30 of a subject 90 and at least three positioning members 1, which is acquired by performing X-ray CT imaging of the positioning members 1 together with the subject 90; measuring relative positions between the subject 90 and each one of the positioning members 1; and based on the CT data 30, three-dimensional design data 31 of the subject 90, and relative position information 32, performing positioning between the subject 90 in the CT data 30 and the subject 90 in the design data 31.SELECTED DRAWING: Figure 5
