Patent ID: 10181189

Abstract:
A quantitative method for nuclear medicine heart image and an electronic device are provided. The method is adapted for multi-pinhole SPECT images or SPECT/CT images. The method includes a radionuclide physical decay correction, a scatter correction, a geometry distortion correction, a data truncation compensation, a tissue attenuation correction, an image space resolution recovery, a noise removal, a pixel value conversion, a myocardial blood flow quantitative calculation, an intra-scan patient movement correction and a blood flow condition evaluation. Accordingly, a quantitative SPECT reconstructed image of a heart is obtained, and an absolute quantization of the myocardial blood flow is calculated to measure the myocardial blood flow quantitatively according to the quantitative SPECT reconstructed image. In addition, a blood flow condition diagram according to a number of indicators is established, and a myocardial blood flow condition is evaluated according to a quantization result of myocardial blood flow and the blood flow condition diagram.
