  • Systems and methods for motion estimation in PET imaging using AI image reconstructions
    Patent number: 11468607
    Abstract: An image reconstruction system generates a motion estimation using images that have been reconstructed using AI processing. The system receives listmode data collected by an imaging system and produces two or more histo-images based on the listmode data. The system provides the two or more histo-images to an AI system and receives two or more AI reconstructed images back from the AI system based on the two or more histo-images. The system generates a motion estimation based on the two or more AI reconstructed images.
    Type: Grant

  • SYSTEMS AND METHODS FOR SIMULTANEOUS ATTENUATION CORRECTION, SCATTER CORRECTION, AND DE-NOISING OF LOW-DOSE PET IMAGES WITH A NEURAL NETWORK
    Publication number: 20220130079
    Abstract: An image reconstruction system generates de-noised, attenuation corrected, and scatter corrected images using AI processing. The system receives a low-dose PET image and applies a machine learning algorithm via a convolutional neural network to the low-dose PET image to generate an output image. The output image includes correction for scatter and attenuation associated with the image being low-dose. The system provides the output image to a computing device comprising a user interface.
