Imaging system

Abstract

A method and apparatus for reconstruction of a region of interest for an object is provided. The reconstruction of the object may be based on chords which may fill a part, all, or more than all of the region of interest. Using chords for reconstruction may allow for reducing data acquired and/or processing for reconstructing a substantially exact image of the ROI. Moreover, various methodologies may be used in reconstructing the image, such as backprojection-filtration, and modified filtration backprojection.

1 . A method of imaging at least a part of a region of interest (ROI) comprising:
 moving a source relative to the ROI in a trajectory, the trajectory defining chords that connect points along the trajectory such that the chords do not intersect the ROI;   collecting data from at least one sensor as the source moves relative to the ROI; and   generating a substantially exact reconstruction of the ROI based on the data collected.
