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.

Abstract

An individualized imaging method, comprising the steps of: scanning the mold of the object to be imaged, calibrating, correcting and optimizing the imaging system through the information obtained after imaging the mold; using the calibrated, corrected and optimized imaging system to image the object Scanning; optimizing the information obtained by scanning the imaging object and its model to obtain higher-quality imaging results and data analysis results; using the higher-quality imaging results and data analysis results to optimize the model for next time imaging use. The individualized imaging method of the present invention makes full use of people's prior knowledge. By building individual models one by one, the image data information of the models can be used to calibrate, correct and optimize the imaging system, and the image data information of the imaging object Optimizing, and further optimizing the model, repeating this cycle, can obtain higher-quality imaging results and data analysis results.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a method for making a mold of 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 is not 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 phantom to obtain an 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 the image data information Img1. 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 sy...
