  • Method and apparatus for aligning a multi-modality imaging system
    Patent number: 8077943
    Abstract: A method of determining component misalignment in a multi-modality imaging system includes imaging a plurality of target objects with a first modality unit to generate a tomographic image data set and imaging the plurality of targets with a second modality unit to generate an emission image data set. The method also includes determining a location of the target objects in the emission image data set to produce emission target object location coordinates, calculating a positional alignment vector for each target object based on the emission target object location coordinates, and aligning the multi-modality imaging system based on the positional alignment vectors.
    Type: Grant
