US patent 10117625, titled "Methods and systems for retrospective internal gating," was issued to Memorial Sloan Kettering Cancer Center.

Here's a concise summary:

• Title: Methods and systems for retrospective internal gating
• Assignee: Memorial Sloan Kettering Cancer Center
• Inventors: Adam L. Kesner
• Filing Date: October 9, 2017
• Issue Date: November 6, 2018
• Abstract: The patent describes a method for deriving respiratory gated PET image reconstruction from raw PET data. It uses respiratory motion information derived from individual voxel signal fluctuations, combined to create usable respiratory phase information. This approach enables the reconstruction of respiratory gated PET images without external hardware and in a fully automated manner.

Independent Claims Overview:

• Claim 1 (Method): This claim describes a method for retrospective internal gating involving several steps:

  1. Acquiring a series of images over time (t1...tn) that include a moving object.
  2. Extracting time-activity information for individual voxels within these images.
  3. Generating a time-varying object motion function based on this extracted time-activity information.
  4. Using the generated motion function to determine phase information for the moving object's motion.
  5. Generating an updated series of images that correct for the object's motion using the determined phase information.

• Claim 19 (Non-transitory computer-readable medium): This claim covers a non-transitory computer-readable medium encoded with a program. When executed by one or more processors, the program causes a machine to perform the same five steps as outlined in independent Claim 1 (acquiring images, extracting time-activity, generating motion function, determining phase information, and generating corrected images).

• Claim 20 (System): This claim describes a system comprising one or more processors and a non-transitory computer-readable medium. This medium stores instructions that, when executed by the processors, cause the system to perform the identical five steps described in independent Claim 1 (acquiring images, extracting time-activity, generating motion function, determining phase information, and generating corrected images).

Regarding CAFC 2026 dockets, no results were found for US patent 10117625 for the year 2026. This indicates that there are no publicly available records of litigation involving this specific patent in the Court of Appeals for the Federal Circuit for the specified period.
