Here is an analysis of the patent citations listed in US patent 10117625, identifying potentially relevant prior art under 35 U.S.C. § 102. The focus is on patents whose titles suggest a connection to motion correction, gating, or image processing for medical imaging.

Most Relevant Prior Art for US10117625

The following patents are cited in US10117625 and appear to be highly relevant due to their focus on motion correction, gating, or related image processing techniques.

  1. US6298260B1

    • Full Citation: US6298260B1, "Respiration responsive gating means and apparatus and methods using the same," issued to St. Jude Children's Research Hospital.
    • Publication/Filing Date: Publication date: 2001-10-02; Priority date: 1998-02-25.
    • Brief Description: This patent describes means, apparatus, and methods for respiratory responsive gating.
    • Potential Anticipation: This patent potentially anticipates aspects of Claims 1, 19, and 20 relating to the general concept of "gating" in response to physiological motion, specifically respiration, and the methods/systems for achieving it. While US10117625 emphasizes "retrospective internal gating" using voxel time-activity, this prior art establishes the broader concept of respiratory gating.

  2. US6144874A

    • Full Citation: US6144874A, "Respiratory gating method for MR imaging," issued to General Electric Company.
    • Publication/Filing Date: Publication date: 2000-11-07; Priority date: 1998-10-15.
    • Brief Description: This patent details a method for respiratory gating specifically for Magnetic Resonance (MR) imaging.
    • Potential Anticipation: This citation directly addresses "respiratory gating method," which is a core application of US10117625. It potentially anticipates the general methodological steps of respiratory gating and acquiring images (Claim 1), and by extension, the computer-readable medium (Claim 19) and system (Claim 20) configured to perform such a method, particularly within the context of medical imaging where MR is a common modality.

  3. US6539074B1

    • Full Citation: US6539074B1, "Reconstruction of multislice tomographic images from four-dimensional data," issued to General Electric Company.
    • Publication/Filing Date: Publication date: 2003-03-25; Priority date: 2000-08-25.
    • Brief Description: This patent concerns the reconstruction of multislice tomographic images using four-dimensional data, which often implies a temporal dimension to account for motion.
    • Potential Anticipation: The concept of using "four-dimensional data" (which includes time) for image reconstruction to address motion is relevant. It could potentially anticipate aspects of Claim 1 related to processing a series of images over time (t1...tn) and generating updated images, particularly if the "four-dimensional data" implicitly or explicitly incorporates motion phase information, and thus, Claims 19 and 20 by extension.

  4. US20050123183A1

    • Full Citation: US20050123183A1, "Data driven motion correction for nuclear imaging," issued to Paul Schleyer.
    • Publication/Filing Date: Publication date: 2005-06-09; Priority date: 2003-09-02.
    • Brief Description: This publication describes methods for "data driven motion correction" specifically for "nuclear imaging."
    • Potential Anticipation: This is highly relevant as US10117625 specifically mentions PET (a nuclear imaging modality) and emphasizes "software derived respiratory signals" or "image based methods." The title "Data driven motion correction" directly aligns with the internal gating approach of US10117625, which uses extracted image data (voxel time-activity) to generate a motion function. This citation potentially anticipates Claims 1, 19, and 20, especially regarding using image data for motion correction without external hardware.

  5. US7359535B2

    • Full Citation: US7359535B2, "Systems and methods for retrospective internal gating," issued to Ge Medical Systems Global Technology Company, Llc.
    • Publication/Filing Date: Publication date: 2008-04-15; Priority date: 2003-06-20.
    • Brief Description: This patent shares the exact title "Systems and methods for retrospective internal gating" with US10117625.
    • Potential Anticipation: Given the identical title, this patent is critically relevant and likely anticipates fundamental aspects of Claims 1, 19, and 20. It would likely teach the core concepts of acquiring images, extracting internal motion signals, determining phase information, and generating corrected images retrospectively. The differentiation for US10117625 would lie in the specific mechanism of internal signal extraction (e.g., individual voxel time-activity information) and the method of generating the time-varying object motion function, which would need careful comparison.

  6. US7574249B2

    • Full Citation: US7574249B2, "Device-less gating of physiological movement for improved image detection," issued to General Electric Company.
    • Publication/Filing Date: Publication date: 2009-08-11; Priority date: 2005-02-08.
    • Brief Description: This patent describes a method for "device-less gating of physiological movement" to improve image detection.
    • Potential Anticipation: The term "device-less gating" strongly aligns with the "retrospective internal gating" and "software derived respiratory signals" aspects of US10117625, which aims to avoid external hardware. This directly addresses a key advantage highlighted in the description of US10117625. Therefore, it potentially anticipates aspects of Claims 1, 19, and 20 related to motion gating without external sensors, particularly for physiological movements.

  7. US20080253636A1

    • Full Citation: US20080253636A1, "Respiratory motion extraction from tomographic projection and image data," issued to Deller Timothy W.
    • Publication/Filing Date: Publication date: 2008-10-16; Priority date: 2007-04-11.
    • Brief Description: This publication focuses on extracting respiratory motion from "tomographic projection and image data."
    • Potential Anticipation: This is highly relevant as it explicitly mentions extracting respiratory motion from image data, which is a core step in US10117625's method of generating a time-varying object motion function from voxel time-activity information. It potentially anticipates the steps of extracting time-activity information for voxels and generating a motion function (Claim 1), and thus the corresponding computer-readable medium (Claim 19) and system (Claim 20).

  8. US9814431B2

    • Full Citation: US9814431B2, "Methods and systems for retrospective internal gating," issued to Memorial Sloan Kettering Cancer Center.
    • Publication/Filing Date: Publication date: 2017-11-14; Priority date: 2007-05-04.
    • Brief Description: This patent shares the identical title "Methods and systems for retrospective internal gating" and the same assignee and priority date as US10117625.
    • Potential Anticipation: This is a key reference. Given it shares the same priority date and assignee, it is likely a parent or related application within the same patent family. Therefore, it directly covers the fundamental inventive concept. It is not "prior art" in the traditional sense for anticipation under 35 U.S.C. § 102 if it's part of the same inventive entity and priority chain, but it is certainly the most relevant document outlining the same invention. It would describe the core method of retrospective internal gating, including acquiring images, extracting voxel time-activity information, generating a time-varying object motion function, determining phase information, and generating corrected images, thereby covering all claims (1, 19, 20) of US10117625.
