  • CNN-based abnormality score map for SPECT gamma camera flood analysis
    Patent number: 11067705
    Abstract: A method for determining an abnormality score map for Single-photon Emission Computed Tomography (SPECT) gamma camera flood analysis includes extracting a plurality of image patches from an input flood image and generating a feature vector for each image patch. A per-patch abnormality score is generated for each feature vector by comparing the feature vector against a normal flood feature dictionary comprising one or more normal flood feature vectors generated using a plurality of normal flood images. Then, an abnormality score map may be generated to depict the per-patch abnormality scores for the input flood image.
