Embodiment Construction

[0034] The PET image acquisition method and system proposed by the present invention will be further described in detail below in conjunction with the drawings and specific embodiments. According to the following description and claims, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and all use imprecise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0035] Please refer to figure 1 , Which is a flowchart of a PET image acquisition method in an embodiment of the present invention, such as figure 1 As shown, the PET image acquisition method includes the following steps:

[0036] First, perform step S1 to acquire the first PET data and the first PET image of a scanned object through PET scanning;

[0037] Next, perform step S2 to obtain the first CT image of the scanned object;

[0038] Please refer to Fi...

Abstract

The invention provides a PET image acquiring method and system. The method comprises registering a first PET image and a corrected second PET image to acquire a motion field of an image space between the corrected first PET image and a second PET image; harmonizing a first CT image using the motion field to acquire a second CT image of a scanned object; carrying out attenuation correction on second PET data using the second CT image to acquire the corrected second PET iamge. According to the PET image acquiring method and system, the corrected second PET image can be acquired through carrying out attenuation correction on second PET data using the second CT image, a process for acquiring the second CT image through secondary CT scanning can be omitted, time of X-ray radiation during CT scanning can be shortened, and a better clinic experience can be achieved.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for acquiring a PET image. Background technique [0002] Positron Emission Computed Tomography (PET) is a neuroimaging inspection instrument developed rapidly after Computed Tomography (CT). At present, it has highlighted important value in the diagnosis and treatment of the three major types of diseases: tumor, coronary heart disease and brain disease. It is a relatively advanced clinical examination imaging technology in the field of nuclear medicine. It can inject a radioactive tracer into a living organism without changing the physiological state to participate in the physiological metabolism of the living organism. The positron generated by the decay of the tracer marker, the positron has an annihilation effect, and a 511 keV gamma photon pair emitted in reverse. Use coincidence detection technology to detect the photon pairs appearing in pa...
