    摘要： 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. A second iteration, for identifying preferred sets of views for measurements of a portion of a body structure, based on models of a location of a pathology that has been identified, makes it possible, in effect, to zoom in on a suspected pathology. The systems are preprogrammed to provide these motions automatically.

    摘要： 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.
