The invention relates to a
nuclear medicine heart
image quantification technology, in particular to to a technological method for multi-pinhole SPECT or SPECT / CT dynamic image quantitative reestablishment and myocardial
blood flow absolute quantification measurement and application of the technological method in myocardial
blood flow state evaluation. The technological method includes the specific steps of
nuclide physical decay correction, in-scanning patient movement correction,
scattering correction, geometric warping correction,
data truncation compensation, tissue attenuation correction,
noise removal, pixel value conversion, myocardial
blood flow quantitative calculation and blood flow state evaluation. With the technological means, a quantitative multi-pinhole SPECT dynamic heart image can be generated, myocardial blood flow
absolute quantification calculation can be carried out through the quantitative multi-pinhole dynamic image, and thus quantitative measurement of the myocardial blood flow is achieved; meanwhile, a blood flow
state diagram is established with the three indexes of resting blood flow, load blood flow and blood flow reserve and is put into the practical application of evaluating the myocardial blood flow state, the purpose of carrying out quantitative measurement of the myocardial blood flow with multi-pinhole SPECT and SPECT / CT dynamic development is achieved, and the technological method can be applied to evaluation of the myocardial blood flow state.
