  • Publication number: 20120172699
    Abstract: A method for predefining a set of radioactive-emission measurement views, for radioactive-emission imaging after an administration of a radiopharmaceutical, the method being tailored to a specific body structure and optimized with respect to the information gained about the body structure and based on modeling body-structure, based on its geometry and anatomical constraints, which limit accessibility to the body structure.

  • Patent number: 8094894
    Abstract: Systems, methods, and probes are provided for functional imaging by radioactive-emission-measurements, specific to body structures, such as the prostate, the esophagus, the cervix, the uterus, the ovaries, the heart, the breast, the brain, and the whole body, and other body structures. The nuclear imaging may be performed alone, or together with structural imaging, for example, by x-rays, ultrasound, or MRI. Preferably, the radioactive-emission-measuring probes include detectors, which are adapted for individual motions with respect to the probe housings, to generate views from different orientations and to change their view orientations. These motions are optimized with respect to functional information gained about the body structure, by identifying preferred sets of views for measurements, based on models of the body structures and information theoretic measures.

  • Patent number: 8000773
    Abstract: A method of imaging, including receiving radioactive radiation from a body; reconstructing a 3D SPECT image of a distribution of radiation in at least one voxel of said body; and reconstructing a dynamic change in radiation in said voxel, as an updated image, at a rate of faster than one change per 5 minutes, wherein said reconstructed image is a clinically useful image including a resolution of 10 mm or better for a voxel volume of at least 5 cm in diameter and a contrast to background ratio of radiation of at least 2:1.

  • Publication number: 20090201291
    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.

  • Publication number: 20080260228
    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.
