Problems solved by technology

However, the disadvantage is that because nuclear medicine uses radiopharmaceuticals to understand changes in brain function, different nuclear medicine radiopharmaceuticals have different absorption distributions in brain tissue, which will affect the contrast of the image and cause spatial alignment errors between images

Abstract

The invention provides a method and system for quantitative analysis of nuclear medicine brain imaging. The method comprises retrieving a target image, wherein the target image is a brain image as a nuclear medicine image produced from a radiopharmaceutical, then matching the position of a space axis and the size of a voxel of the target image to a standard template by an affine transformation, wherein the standard template comprises a relative position of striatum. The method further comprises selecting the striatum from the target image according to the relative position of the striatum in the standard template and calculating an average value of the striatum, dividing the striatum from the target image and calculating a background value based on a remainder pixel value of the target image, and a specific uptake ratio is calculated based on the average value of the striatum and the background value.

Description

technical field [0001] The present invention relates to a nuclear medicine tomography system and method, in particular to a system and method for quantitative analysis of nuclear medicine brain images. Background technique [0002] When nuclear medicine is applied to the diagnosis of Parkinson's disease or damage to dopamine neurons, it is not easy to diagnose from clinical symptoms alone. However, traditional neuroimaging studies, such as computed tomography or MRI, often only provide structural abnormalities. Recent developments in nuclear medicine, such as single-photon computed tomography (SPECT), use many different radioisotopes to bind to presynaptic neurons or postsynaptic receptors, which can reflect the dopamine system before and after synapses. Abnormalities in the function of neurons provide considerable help in the diagnosis of Parkinson's disease or damage to dopamine neurons. [0003] At present, in the diagnosis of Parkinson's disease, in addition to evaluat...
