RECONSTRUCTION STABILIZER AND ACTIVE VISION

摘要

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. Additionally, a method is described for performing radioactive-emission measurements of a body structure. The method is dynamically defining further views for measurements, based on an analysis measurements results obtained during the current emission measurement procedure. The definition of the further views is performed without terminating the current measurement process. The preferred sets of views may then be applied immediately to the body structure. The method may be performed iteratively, to zoom in on a region of interest. The dynamically-defined views may be provided as the modifications defined by the method to improve the reliability of reconstruction.
