Abstract

The invention discloses a PET-CT scanning imaging method and a related imaging method. The PET-CT scanning imaging method includes: positioning and scanning the area to be imaged, obtaining and displaying a positioning image of the area to be imaged, and the displayed positioning image It is used for the user to determine the scan area; receive the scan area information input by the user, and determine the PET total scan area according to the scan area information; generate multiple PET sub-scan areas from the PET total scan area, and each PET sub-scan area Corresponding to a PET scanning bed, each PET sub-scanning area is superimposed to completely cover the total PET scanning area; performing multi-bed PET scanning; performing CT scanning; reconstructing a PET-CT image from scanning data. The technical scheme of the present invention eliminates irrelevant scanning areas in PET-CT scanning imaging, reduces the scanning time of PET-CT, and reduces the CT radiation dose received by patients in PET-CT scanning.

Description

technical field [0001] The invention belongs to the field of medical imaging, in particular to a PET-CT scanning imaging method and a related imaging method. Background technique [0002] PET (Positron Emission Tomography) imaging technology uses labeled glucose, amino acids, thymine, receptor ligands or blood flow imaging agents as tracers to display the body and lesions at the molecular level in anatomical images. The metabolism, function, blood flow, cell proliferation or receptor distribution of tissue cells provides more physiological and pathological diagnostic information for clinical practice, and has excellent performance in helping early diagnosis of cancer. [0003] However, PET images only show the cumulative distribution of the labeled nuclei in the human body, and do not directly reflect the anatomical structure of the human body, so the anatomical position of the labeled nuclei in the human body cannot be accurately displayed. Therefore, in order to make a be...
