Problems solved by technology

In the prior art, the alignment of the two frames is mainly achieved by processing the precise mating surfaces on the PET frame and the CT frame to achieve alignment during installation. This method greatly increases the processing difficulty and manufacturing cost; another alignment method is to install support blocks on the ground and precisely calibrate the height and mutual position of these support blocks to ensure the alignment of the PET frame mounted on the support blocks with the CT frame, but this This calibration method is very complicated and the required calibration tools are expensive

Abstract

The invention provides an indicating device and an indicating method for PET-CT(positrom emission tomograghy-computed tomography) rack mounting alignment. The indicating method includes the steps of respectively mounting a CT central indicating component and a PET central indicating component on a CT rack rotating part and a PET rack; by a laser of the CT central indicating component, emitting a laser beam to the PET rack for indicating a CT rotation center, regulating positions of front and back supporting points of the PET rack, aligning the laser beam to a first central indicator and a second central indicator on the PET central indicating component, thereby achieving alignment between the CT rotation center and the center position of a PET probe. The indicating device is simple in structure and convenient to regulate; by the indicating device and the indicating method, influence from processing and mounting error of the CT central component can be eliminated, alignment precision is high, and the requirement on the mounting coaxiality of the PET probe center and the CT rotation center is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an indicating device and method for installing and aligning a PET-CT frame. Background technique [0002] Computed Tomography (Computed Tomography, CT) is a combination of computer and X-ray inspection, using the different attenuation coefficients of X-ray transmission by different tissues of the human body, so that the radiation signals received by the detector are different, and reconstruct the tomographic image of the human body. Technology. Positron Emission Tomography (PET) is a technique that uses positron nuclide as a tracer to understand the functional metabolic state of the lesion through the uptake of the tracer at the lesion site, and then diagnose the disease. [0003] PET-CT is an organic combination of PET and CT. Using the same examination table and the same image processing workstation, the PET image and CT image are reconstructed and fused to form a PET-...
