Abstract

The embodiment of the invention provides a medical imaging method and a device, relates to the technical field of medicines and aims to solve the problem of PET image artifacts. The method comprises the following steps: firstly, acquiring a PET original data corresponding to an appointed area in an imaging area, and then acquiring motion information of the appointed area; screening the PET original data corresponding to multiple time periods that meet an appointed condition from the PET original data corresponding to the appointed area according to the motion information of the appointed area; and performing image reconstruction on the PET original data corresponding to multiple time periods, thereby acquiring a PET image corresponding to the appointed area. The technical scheme provided by the embodiment of the invention is suitable for medical imaging process.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of medical technology, in particular to a medical imaging method and device. [0003] 【Background technique】 [0004] PET (positron emission tomography, positron emission tomography) is a display device that reflects the gene, metabolism and functional status of the disease. CT (computed tomography, computer X-ray tomography) uses X-rays to scan the human body. Due to the different density of tissues in various parts of the human body, the penetration of X-rays is affected, resulting in differences in the X-rays received by the scanning detector. , so that the lesion can be precisely located, and the fine structure changes of the lesion can be projected, but CT cannot reflect the physiological metabolism of the disease. [0005] PET-CT is an organic combination of PET and CT, using the same examination bed and sharing an image workstation, and combining PET images and CT images through image workstation proce...
