Patent ID: 8653464

Claim:
A dual-modality imaging system, wherein at least one single photon emission computed tomography (SPECT) camera for acquiring SPECT data and at least one optical imaging detector for acquiring optical imaging data are arranged to acquire the SPECT data and the optical imaging data of an imaged object simultaneously and from the same projection angle, the at least one optical imaging detector being a non-contact optical imaging detector for bioluminescence, fluorescence, and reflectance imaging and wherein the SPECT sub-system apparatus comprises a SPECT-detector to which a collimator is attached for high-resolution/high-sensitivity radio-nuclide imaging and at least one optical imaging detector being arranged within the imaging volume to detect photons emitted by the imaged object, characterized in that the at least one optical imaging detector comprises a micro-lens array with a plurality of micro-lenses, the optical detector being attached onto the surface of the collimator of the SPECT system.
