The method comprises providing a first system of voxels for a region of interest, obtaining radioactive-emission data from the region of interest, performing a first reconstruction, based on the radioactive-emission data and the first system of voxels, to obtain a first image, correcting the first system of voxels, by aligning voxel boundaries with object boundaries, based on the first image; thus obtaining a second system of voxels, and performing a second reconstruction, based on the radioactive-emission data and the second system of voxels, thus obtaining a second image.

Diagnostic kit and methods for radioimaging myocardial perfusion

Номер: US9040016B2
Принадлежит: Biosensors International Group Ltd

A method of radioimaging a myocardial perfusion, the method including in sequence: administering to a subject a low dose of a first radiopharmaceutical; subjecting the subject to a physical stress; administering to the subject at a peak of said physical stress a medium or high dose of a second radiopharmaceutical; and immediately radioimaging using a 3D non-coincidence imaging method a heart of the subject, thereby radioimaging a myocardial perfusion.

System and method for radioactive emission measurement

Номер: US8586932B2
Принадлежит: Spectrum Dynamics LLC

A method of radioactive-emission-measurement. The method comprises providing a camera for the detection of single emissions, which defines proximal and distal ends. The camera is configured for enabling a reconstruction of a volumetric image having a line spread function of less than 7 mm Full Width Half Maximum (FWHM) when given a substantially line source of radioactive emission, with an activity of 5 mCi, within a region-of-interest volume, at a distance of at least 100 mm from said distal end, with air being substantially the only operating medium. The method further comprises detecting at least 1 of every 5000 photons, emitted from at least one radioactive-emission source, located within a certain region-of-interest volume, using the camera, and reconstructing a volumetric radioactive-emission image from the detected photons.
