Title: Methods and systems for retrospective internal gating

Assignee: Memorial Sloan Kettering Cancer Center

Inventor: Adam L. Kesner

Filing Date: November 1, 2018 (Application number US16/178,332)

Issue Date: October 22, 2019

Abstract: The invention describes a method for reconstructing respiratory-gated Positron Emission Tomography (PET) images from raw PET data. It uses respiratory motion information derived from signal fluctuations of individual voxels 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:

• Claim 1 (Method): This claim describes a method for retrospective internal gating that involves:

  1. Acquiring a series of images over time (t1...tn) which include a moving object.
  2. Extracting time-activity information for the individual voxels (3D pixels) within these images.
  3. Determining the phase information of the moving object's motion using this extracted time-activity information.
  4. Generating an updated series of images where corrections have been applied to account for the moving object's motion, utilizing the previously determined phase information.

• Claim 19 (Non-Transitory Computer-Readable Medium): This claim covers a computer-readable storage medium containing a program. When a processor executes this program, it instructs a machine to perform the same steps as outlined in Claim 1: acquire images, extract voxel time-activity information, determine motion phase information, and generate corrected images.

• Claim 20 (System): This claim describes a system that includes one or more processors and a non-transitory computer-readable medium. The medium stores instructions that, when executed by the processors, cause the system to perform the same method as described in Claim 1: acquire images, extract voxel time-activity information, determine motion phase information, and generate corrected images.
