Abstract

The invention relates to a positron emission tomography simulation method based on numerical calculation. The method comprises the following steps: constructing a standard sample or a human tumor model; constructing a PET drug model; constructing a radionuclide drug emission and annihilation model; constructing a geometric model of the PET detector; constructing a photon pair coincidence detectioncalculation model; filling and displaying a PET original data sinogram; reconstructing a sinogram to obtain a PET image; and PET image storage and display. The invention further relates to a positronemission tomography simulation system based on numerical calculation. According to the invention, the PET imaging principle is dynamically visualized without hardware and radiopharmaceutical support.

Description

technical field [0001] The invention relates to the technical field of positron emission tomography simulation technology, in particular to a numerical calculation-based positron emission tomography simulation method and system. Background technique [0002] Positron Emission Computed Tomography (PET) is a large-scale medical imaging device. Its images can display the differences in metabolic functions of tissues and organs that appear at the early stage of the disease, so as to achieve early diagnosis and lay the foundation for early treatment of diseases. Therefore, more and more attention has been paid to it, and its application has become more and more extensive. However, in the teaching process, there are problems such as abstract and difficult to understand imaging theory, expensive and large-scale equipment, ionizing radiation hazards, and special requirements for experimental sites, which make it difficult or impossible to carry out experimental teaching, and cause a...
