Embodiment Construction

[0036] The following detailed description is of the best mode presently contemplated for carrying out exemplary embodiments of the invention. Since the scope of the invention is best defined by the appended claims, this description is intended only to illustrate the principles of the invention and should not be taken in a limiting sense.

[0037] In summary, an embodiment of the present invention provides a quantitative single-photon emission computed tomography (SPECT) reconstruction system for performing myocardial blood Quantification of flow (MBF) and coronary flow reserve (CFR). The present invention solves the problems of physical interference and patient motion in dynamic SPECT imaging to have quantification capability for MBF and CFR quantification.

[0038] The capture of SPECT is a form of image data obtained by a SPECT camera going around the patient after injection of the tracer at 180 degrees or 360 degrees. In each rotation, projections or projection data are r...

Abstract

A quantitative Single Photon Computed Emission Tomography (SPECT) reconstruction system for myocardial blood flow quantitation with SPECT or Single Photon Emission Computed Tomography / Computed Tomography (SPECT / CT) dynamic imaging. The present invention solves the problems of physical interference and patient motions in dynamic SPECT imaging to enable the quantitative ability for myocardial blood flow (MBF) and coronary flow reserve (CFR) quantification.

Description

technical field [0001] The present invention relates to a quantitative single-photon emission computed tomography (single-photon emission computed tomography, SPECT) image reconstruction system, in particular to an image reconstruction system for correcting and using single-photon emission computed tomography (SPECT) or single-photon emission computed tomography (SPECT) A system for measuring myocardial blood flow (MBF) and coronary flow reserve (CFR) using photon emission computed tomography (SPECT) / computed tomography (CT) images. Background technique [0002] The imaging mode of SPECT and SPECT / CT are widely used in hospitals, but the diagnosis often suffers from image artifacts and insufficient accuracy. Positron emission tomography (PET) imaging modalities, including positron computed tomography (PET / CT), are quantitatively accurate, but their widespread use in hospitals is limited by problems such as lack of drugs and high financial burden. [0003] In order to measur...
