Abstract

The embodiment of the invention provides a data processing method and device and a medical image obtaining method. According to the embodiment of the invention, the method comprises the steps: obtaining the PET data corresponding to each of a plurality of movement regions through recognizing the movement regions in a reconstruction area of a detected object; determining a movement correction modecorresponding to each movement region, wherein the movement regions corresponding to at least two movement regions are different; carrying out the correction of the PET data corresponding to each movement region in the movement correction mode corresponding to the movement region, and obtaining the corrected PET data corresponding to each movement region; correcting each movement region in the reconstruction area in the movement correction mode corresponding to the movement region, and enabling each movement region to be corrected accurately, thereby improving the accuracy of the corrected PETdata, improving the quality of a PET image obtained through the reconstruction of the corrected PET data, and solving a problem that the PET image quality is poorer in the prior art.

Description

【Technical field】 [0001] The solution relates to the technical field of image processing, in particular to a data processing method, equipment and a method for acquiring medical images. 【Background technique】 [0002] PET (Positron Emission Computed Tomography) equipment is a relatively advanced medical imaging equipment. The principle is: injecting isotope-labeled drugs (i.e. imaging agents) with positron emission into the human body, such as one or two isotopes of carbon, fluorine, oxygen and nitrogen, these drugs participate in the physiological metabolism process of the human body An annihilation effect occurs, generating two gamma ray light quanta with energy 0.511 MeV moving opposite to each other, basically emitted in a 180-degree direction. [0003] According to the difference in the ability of different parts of the human body to absorb labeled drugs, the degree of concentration of the isotope in each part of the human body is different, and the intensity of the ph...
