Patent ID: 8000773

Claim:
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 2:1.
