1. A method of imaging, comprising:
- (a) receiving radioactive radiation from a body;
(b) reconstructing a 3D SPECT image of a distribution of radiation in a plurality of voxels that correspond to portions of said body;
(c) reconstructing a dynamic change in radiation in said voxels, as an updated image, at a rate of faster than one change per 5 minutes; and
(d) administrating a radiopharmaceutical to a patient, wherein said reconstructing at least one of (b) or (c) uses radioactive radiation data collected at a time period overlapping in time with said administration, 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 target to background ratio of radiation of at least 2;

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.

24. Apparatus for imaging, comprising:
-
(a) a camera adapted for receiving radioactive radiation from a body; (b) a radiopharmaceutical administration timing determination circuit; and (c) a controller configured to; (i) reconstruct a 3D SPECT image of a distribution of radiation in a plurality of voxels that correspond to portions of said body; (ii) reconstruct a dynamic change in radiation in said voxels, as an updated image, at a rate of faster than one change per 5 minutes ; and (iii) time the collection of radioactive radiation data used for said reconstruction of at least one of (i) or (ii) so as to overlap in time with radiopharmaceutical administration, using said administration timing circuit, 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 target to background ratio of radiation of at least 2;
