Abstract

The invention provides a medical imaging method and a medical imaging system. The method comprises the following steps: getting scanning data; getting correction coefficients, including a normalization correction coefficient and a total count quantitative uniformity correction coefficient; correcting the scanning data with the correction coefficients to get corrected scanning data; performing image reconstruction with the corrected scanning data to get reconstructed images. Through the method, after a user performs normalization correction on scanning data, the SUV values of reconstructed images are kept consistent.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a medical imaging method and system. Background technique [0002] The detector of the positron emission tomography (PET) system is composed of many modules, and the photon yield of many crystal blocks and the gain of the photomultiplier tube are inevitably different. This non-uniformity of performance will cause various Inconsistencies in detection efficiency of detector modules. In addition, the sensitivity of the detector is related to the geometry and size of the probe. The process of correcting for factors that cause differences in detector sensitivity is called normalization of the detector. [0003] The method of correction is to apply the normalization coefficient to normalize each response line. The normalization coefficient is the average value of all coincidence counts in the detection field of view and the normalization coefficient of each pair of...
