Original Abstract Submitted
TDS (Time-Delayed Summation) acquisition systems and methods may be used within various imaging device and systems, such as a densitometry system with highly pixelated 2-D detectors and compact x-ray fan beam that scans patients in a rastering pattern across the patient axis. An improved system and method is described for extending the usability of TDS data on each transverse sweep of the scan, by acquiring data when the scan speed is variable. In this method, the TDS shift strobe signal is no longer a constant periodic function. Instead the time between strobes is dependent on the scan velocity and the strobe sequence is generated to provide constant sampling distance between strobes. Thus, the TDS shift sequence insures a constant image pixel size, enabling undistorted images despite the variable speed occurring during the signal summation.
