Problems solved by technology

Since the patient cannot be imaged before the bed board 131 moves to the CT scanning surface, the farther the distance between the initial position of the bed board 131 and the CT scanning surface is, the greater the scanning range of the CT imaging unit 11 is when the stroke of the bed board 131 is constant. smaller

Abstract

The invention relates to the field of medical imaging and discloses an imaging method and device. The imaging device comprises an acquiring unit for acquiring images, a determining unit, a height adjusting unit and an imaging unit for executing imaging scanning, wherein the determining unit is used for determining the linear relation between the bed board height in the images and the moving distance of a bed board in the length direction of the bed board; the height adjusting unit is used for adjusting the bed board according to the linear relation, so that the surface of the adjusted bed board meets the linear relation. The imaging method and device can compensate the difference between the bed board sinkage in different imaging modes and facilitate image fusion.

Description

technical field [0001] The invention relates to the field of medical diagnosis, in particular to a PET / CT imaging device. Background technique [0002] With the advancement of science and technology, medical imaging technology has made great progress, and there are more and more imaging modes, such as X-ray imaging (X-Ray Photography), magnetic resonance imaging (Magnetic Resonance Imaging, referred to as MRI), computed tomography ( Computed Tomography (abbreviated as CT), positron emission tomography (abbreviated as PET), etc., different imaging modes have their own strengths and complement each other. [0003] For example, PET scanning is a relatively advanced clinical examination imaging technology in the field of nuclear medicine. It uses positron nuclide as a tracer, and the functional metabolic state of the lesion can be understood through the uptake of the tracer by the lesion site, so as to make a correct diagnosis of the disease. PET can display the pathophysiologi...
