Abstract: A method for reconstructing a radioactive emission image of an overall volume having first and second volumetric regions, each volumetric region having respectively independent dynamic characteristics. The method comprises the following steps: a) obtaining radioactive emissions from the overall volume, including the volumetric regions, b) reconstructing an initial radioactive emission image of the volumetric region according to the radioactive emissions, c) segmenting the initial radioactive emission image to delineate the first and second volumetric regions, and d) separately reconstructing the first and the second volumetric regions according to the respectively independent dynamic characteristics.

Abstract: A method of imaging, comprising: (a) providing an isotope at a low dosage in a body of a patient; (b) receiving radiation generated by said isotope from said body using a radiation camera; and (c) reconstructing a 3D distribution of said isotope from said received radiation, wherein the dosage is less than ? of a standard dose set forth in Table 5.

Abstract: 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.

Abstract: A method is described for identifying an optimal, or preferred set of views for radioactive-emission measurements of a body structure, based on modeling the body structure, in terms of its geometry and radioactive emission distribution, obtaining different sets of views of the model, and scoring the different sets of views, with a scoring function, using information theoretic measures, for example, for uniformity, reliability and separability in reconstruction. The preferred set of views may then be applied in imaging the in-vivo body structure, that has been modeled.
