Claim 19:
20. One or more non-transitory computer-readable media embodying instructions executable by a machine to perform operations for gantry alignment comprising:
acquiring first image data of a non-radioactive structure by using intrinsic radiation emitted by scintillator crystals of detectors in a first gantry of a multimodality medical scanner;
acquiring second image data of the non-radioactive structure using a second gantry for another modality of the multimodality medical scanner;
performing image reconstruction based on the first and second image data of the non-radioactive structure to generate first and second reconstructed image volumes; and
determining a gantry alignment transformation that aligns the first and second reconstructed image volumes.
