Abstract

The invention discloses a brain ASL, SPECT and MRI image registration and fusion conjoint analysis method and system. Registration is respectively carried out to an ASL image and an MRI image by taking the MRI image as a standard; the ASL image and an SPECT image are fused according to different transparencies; a region to be computed is marked in the faultage of the SPECT image; a closed curve is obtained through carrying out a cubic spline interpolation to the ASL image; the volume and the gray value corresponding to the region to be computed and the gray value of an interesting region body through a circular truncated cone approach mode. According to the invention, the advantages of the ASL image reflected brain blood perfusion, the SPECT image reflected brain blood perfusion and the MRI provided brain structure change are combined; an interesting region is segmented and analyzed through providing interactive calibration operation a doctor and a medical expert; the judgement accuracy of a brain ischemic disease is improved; and iconography instructions are provided for a clinician to formulate a rational therapeutic schedule.

Description

technical field [0001] The present invention relates to a technology in the field of image processing, specifically a CBF (cerebral blood flow, Cerebral Blood Flow) measured by cerebral blood perfusion imaging of a brain SPECT (Single-PhotonEmission Computed Tomography, single photon emission computed tomography) A method for joint analysis of registration and fusion of ASL (Arterial Spin Labeling) images of imaging and MR (Magnetic Resonance, Magnetic Resonance) imaging belongs to the field of biomedical image processing, specifically a fusion display and display based on multimodal images. Techniques for Region of Interest Segmentation. Background technique [0002] Ischemic cerebrovascular disease is one of the diseases that seriously endanger human health. It has the characteristics of high morbidity, high mortality and high disability rate, and seriously affects people's quality of life. It is of great significance to detect the ischemic area early and provide the basi...
