Speed Variable TDS Operation in X-Ray Imaging Systems
Summary
The USPTO granted patent US12599348B2 to GE Precision Healthcare LLC covering TDS (Time-Delayed Summation) acquisition systems in x-ray imaging with variable scan speed capability. The patent (19 claims, filed September 7, 2023) enables constant sampling distance between strobes regardless of scan velocity, producing undistorted images. Inventors include Adam Manders, Michael R. Buchholz, and James Wear.
What changed
The USPTO issued patent US12599348B2 to GE Precision Healthcare LLC on April 14, 2026. The patent covers TDS (Time-Delayed Summation) acquisition systems for x-ray imaging that adjust strobe timing based on scan velocity to maintain constant sampling distance between strobes, ensuring undistorted images despite variable scan speeds.
Medical device manufacturers developing advanced x-ray, densitometry, or diagnostic imaging systems should monitor this IP for potential licensing implications or design around considerations. The patent's 19 claims protect a specific technical approach to handling variable scan speeds in imaging applications.

Abstract
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.
