Here is a concise summary of US patent 10863950:

US Patent 10863950

• Title: Methods and systems for retrospective internal gating
• Assignee: Memorial Sloan Kettering Cancer Center
• Inventor: Adam L. Kesner
• Filing Date: April 25, 2019
• Issue Date: December 15, 2020
• Abstract: The invention describes a method for reconstructing respiratory-gated PET images from raw PET data. It uses respiratory motion information derived from individual voxel signal fluctuations to create usable respiratory phase information. This method allows for the reconstruction of respiratory-gated PET images without external hardware and in a fully automated manner.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method Claim): This claim describes a method for motion correction in imaging. It involves several steps:

  1. Acquiring image data: Taking images at different times (t1 to tn) of a moving object.
  2. Extracting information: Getting data from multiple "arrays" (which can be understood as voxels or regions of interest) within the image data.
  3. Generating a motion function: Creating a function that shows how the object moves over time, based on the extracted information from these arrays.
  4. Determining phase information: Using this motion function to figure out the different phases of the object's movement (e.g., phases of a breathing cycle).
  5. Generating a corrected image: Producing at least one image that accounts for and corrects the object's motion, using the determined motion phase information and the original image data.

• Independent Claim 21 (Non-transitory Computer-Readable Medium Claim): This claim describes a computer program stored on a non-transitory computer-readable medium (like a hard drive or flash drive). When this program is run by one or more processors, it instructs a machine to perform the exact same steps as described in Independent Claim 1:

  1. Acquire image data.
  2. Extract information for a plurality of arrays.
  3. Generate a time-varying object motion function.
  4. Determine phase information for motion.
  5. Generate at least one image correcting for the motion.

• Independent Claim 22 (System Claim): This claim describes a system that includes one or more processors and a non-transitory computer-readable medium with stored instructions. When these instructions are executed by the processors, they cause the system to perform the exact same steps as described in Independent Claim 1:

  1. Acquire image data.
  2. Extract information for a plurality of arrays.
  3. Generate a time-varying object motion function.
  4. Determine phase information for motion.
  5. Generate at least one image correcting for the motion.
