Embodiment 1

[0064] A PET-CT scanning imaging method is disclosed, comprising the steps of:

[0065] S101. Perform a positioning scan on the area to be imaged, obtain and display a positioning image of the area to be imaged, and the displayed positioning image is used for the user to determine the scanning area;

[0066] S102, receiving scanning area information input by a user, and determining a total PET scanning area according to the scanning area information;

[0067] S103. Generate multiple PET sub-scanning areas from the PET total scanning area, each PET sub-scanning area corresponds to a PET scanning bed, and each PET sub-scanning area completely covers the PET total scanning area after being superimposed;

[0068] S104, performing a CT scan;

[0069] S105, performing a multi-bed PET scan; S106, reconstructing a PET-CT image from the scan data.

[0070] Each step is described in detail below:

[0071] Firstly, step S101 is executed to scan the area to be imaged for positioning, t...

Abstract

The invention discloses a PET-CT scanning imaging method and a related imaging method. The PET-CT scanning imaging method comprises that an area to be imaged is positioned and scanned, the positioning image of the area to be imaged is obtained and displayed, and the displayed positioning image is used for a user to determine the scanning area; the scanning area information which is input by the user is received, the PET total scanning area is determined according to the scanning area information; the PET total scanning area generates a plurality of PET sub scanning areas, each PET sub scanning area corresponds to a PET scanning bed, and the PET sub scanning areas are superposed to cover the PET total scanning area completely,; multi-bed PET scanning is carried out; CT scanning is carried out; and scanning data are reconstructed to obtain PET-CT images. According to the invention, unrelated scanning areas in the PET-CT scanning imaging process are eliminated, the PET-CT scanning time is shortened, and the CT radiation dose received by a patient in the PET-CT scanning imaging process is reduced.

Description

technical field [0001] The invention belongs to the field of medical imaging, in particular to a PET-CT scanning imaging method and related imaging methods. Background technique [0002] PET (PositronEmissionTomography) imaging technology uses labeled glucose, amino acid, thymine, receptor ligands or blood flow imaging agents as tracers to display the body and lesion tissue cells at the molecular level in anatomical images Metabolism, function, blood flow, cell proliferation, or receptor distribution status, provide more physiological and pathological diagnostic information for clinics, and have excellent performance in helping early diagnosis of cancer. [0003] However, PET images only show the cumulative distribution of labeled nuclei in the human body, and do not directly reflect the anatomical structure of the human body, so they cannot accurately display the anatomical position of the labeled atomic nuclei in the human body. Therefore, in order to enable doctors to ma...
