SYSTEMS, METHODS, AND DEVICES FOR REMOVING PROSPECTIVE MOTION CORRECTION FROM MEDICAL IMAGING SCANS

摘要

The disclosure herein provides methods, systems, and devices for removing prospective motion correction from medical imaging scans. In an embodiment, a computer-implemented method for removing motion correction from biomedical imaging scan data comprises tracking, by a computer system, motion of an object being scanned; generating, by the computer system, motion tracking data; adjusting, by the computer system, a biomedical imaging scanner, using the motion tracking data, to compensate in real time for object motion, such that raw image data generated by the scanner can be reconstructed into motion-corrected images; inverting, by the computer system, the motion tracking data; and applying, by the computer system, the inverted motion tracking data to the raw image data to generate de-corrected image data representative of what the scanner would produce had the scanner not compensated for motion, wherein the de-corrected image data can be reconstructed into de-corrected images, wherein the computer system comprises an electronic memory and a computer processor.

主权项

1. A system for generating motion de-corrected images in conjunction with a biomedical imaging scan, the system comprising:
a biomedical image scanner; one or more detectors configured to capture motion data for an object being scanned by the biomedical image scanner; a detector processing interface configured to generate motion tracking data from the captured motion data, the motion tracking data indicating the position of the object being scanned by the biomedical image scanner; a scanner controller configured to adjust the biomedical image scanner using the motion tracking data to compensate in real time for object motions, such that the raw image data generated by the scanner can be reconstructed into motion-corrected images; and an image processing interface comprising:
a motion-corrected images generator configured to reconstruct images based on the raw image data generated by the scanner; anda motion de-corrected images generator configured to generate, based on the raw image data and the motion tracking data, de-corrected image data representative of what the scanner would produce had the scanner not compensated for motion, wherein the de-corrected image data can be reconstructed into de-corrected images.
