1. A method of radioactive-emission measurements of a body structure, comprising:
- performing radioactive-emission measurements of the body structure, at a predetermined set of views taken from different directions;
analyzing the radioactive-emission measurements from the different view directions including extracting a detected photon count; and
dynamically defining at least one view parameter for further radioactive measurements based on said photon count detected from the different view directions from at least a target region, andmatching said dynamically defined at least one view parameter to one or more particular views and view directions.

Abstract
A method for stabilizing the reconstruction of an imaged volume is presented. The method includes the steps of performing an analysis of the reliability of reconstruction of a radioactive-emission density distribution of the volume from radiation detected over a specified set of views, and defining modifications to the reconstruction process and/or data collection process to improve the reliability of reconstruction, in accordance with the analysis.
