Pseudo-color mapping method for SPECT reconstruction data based on adjustable bidirectional quantity parameters

Abstract

The invention relates to medical images, in particular to a pseudo-color mapping method for SPECT reconstruction data based on adjustable bidirectional quantity parameters, the pseudo-color mapping method containing the adjustable bidirectional quantity parameters is provided based on a DICOM file of SPECT, a multi-level mapping relation is created, the method can control the display range of pseudo-colors, and the method can be used for realizing the multi-level mapping of the pseudo-colors, the interested dose area and data range in the SPECT image can be more clearly and accurately displayed, the focus area and dose distribution layering sense of SPECT-CT can be obviously enhanced after the method is fused with the CT image, particle space and radiation dose distribution information of the focus part are accurately displayed, and a reliable basis is provided for the judgment of a clinical curative effect; and according to the technical scheme provided by the invention, the defects that the display range of the pseudo-color image cannot be effectively controlled and the dose multi-level distribution display cannot be regulated and controlled in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to medical images, in particular to a pseudo-color mapping method of SPECT reconstruction data based on adjustable double vector parameters. Background technique [0002] SPECT is a kind of emission imaging, which uses the implanted radioactive particles accumulated on the diseased tissue as the γ-ray source, and the rotatable detector placed outside the body collects the γ-photon information after passing through the human body, and performs tomographic reconstruction based on this information to obtain The dose distribution of gamma rays on the corresponding tissues. SPECT images are mainly used to determine the nature and extent of lesions and belong to functional imaging. Due to the lack of collected photon data, the resolution of SPECT images is low, which needs to be fused with CT images to achieve accurate analysis and diagnosis of lesion location, function and other information. [0003] Usually the reconstructed SPECT i...
