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 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.

Abstract: A stratified, solid-state detector for ionizing radiation, is provided, wherein an operating bias is applied in parallel to all the strata. Since the bias required for accelerating electrons away from holes in a solid-state material is generally a function of material thickness, a stack of thin solid-state-material layers, connected in parallel, will operate at only a fraction of the bias required for a single, thick layer of solid-state-material of an equivalent thickness. Thus, stratification allows for reduced operating voltage and improved manufacturing flexibility. Additionally, a high-voltage power supply need not be used, thus increasing the safety of the detector. Stratification may further provide information on incident-radiation energy, based on depth penetration into the detector, wherein the layers may operate as “depth pixels.” Generally, the higher the incident radiation energy, the greater the probability for deep penetration into the solid state material.
