Manufacturing method of model of object to be imaged and individual imaging method

Abstract

An individualized imaging method, comprising the following steps: scanning an imaging subject mould; conducting calibration, rectification and optimization on the imaging system according to the information obtained after mould imaging; scanning the imaging subject with the calibrated, rectified and optimized imaging system; optimizing information obtained by scanning the imaging subject and the mould thereof to obtain higher quality imaging results and data analysis results; and applying the higher quality imaging results and data analysis results to optimize the mould for use in the next imaging. The individualized imaging method fully utilizes a priori knowledge, establishes a mould for an individual and uses the image data information of the mould to conduct calibration, rectification and optimization on the imaging system, and optimizes the image data information of the imaging subject, and further optimizes the mould. By repeating the above steps, the present invention can obtain higher quality imaging results and data analysis results.

Description

Technical field [0001] The present invention relates to the technical field of medical imaging, in particular to a method for manufacturing an object to be imaged and an individualized imaging method. Background technique [0002] Such as Figure 1 to Figure 4 As shown, in the existing medical imaging technology, the prior knowledge of the object to be imaged has not been fully utilized to obtain higher diagnostic accuracy, less radiation damage and lower cost. For example, when doing PET imaging, a cylinder is used as a prosthesis to obtain image data information Img0, and the image data information Img0 is used for system calibration and system correction, and then the human body is imaged through the calibrated and corrected imaging system , To obtain image data information Img1. This process of calibrating and correcting the imaging system using a cylinder as a prosthesis is rough, and the imaging system itself has not been optimized. [0003] In addition, for some combined im...

AI Technical Summary

Problems solved by technology

This process of calibrating and correcting the imaging system using a cylinder as a phantom is crude and the imaging system itself is not optimized

[0003] In addition, for some combined imaging systems, such as PET-CT combined imaging system, many patients have already had CT before doing PET-CT. Because of the need for attenuation correction, they have to do it again when doing PET-CT CT imaging in PET-CT, in general, CT in PET-CT is low-performance, and the radiation is large

In the diagnosis of some diseases, such as physical examination, etc., the results of CT are not required, which virtually increases the radiation dose of the patient and is harmful to health.
