  • Apparatus for radiopharmaceutical quantification of a body part
    Patent number: 11553888
    Abstract: An apparatus for radiopharmaceutical quantification of a body part includes a processor configured to receive at least one gamma image of a body part acquired by at least one gamma camera configured to detect gamma and/or X-rays. The at least one gamma image comprises spectral energy data that includes data resulting from decay of at least one radiopharmaceutical. The processor is configured to determine an activity of the at least one radiopharmaceutical at a plurality of spatial positions in the body part and determines a spatial distribution of the at least one radiopharmaceutical in the body part. The determination for a spatial position of the plurality of spatial positions comprises correlating a generated synthetic spectrum to an experimental spectrum generated from the spectral energy data for at least one position in the at least one gamma image that corresponds to that spatial position.
