1. A computing system, comprising:
computer readable medium including a positron emission tomography (PET)-to-single photon emission tomography (SPECT) module with instructions for generating simulated SPECT image data based on first PET image data, wherein the first PET image data is acquired prior to a treatment course of a treatment regimen with a SPECT-based treatment/imaging radiopharmaceutical; and
a processor configured to obtain the first PET image data, system parameters of a SPECT-CT imaging system utilized to generate corresponding SPECT image data for the treatment regimen and scan parameters utilized by the SPECT-CT imaging system to acquire the corresponding SPECT image data, and execute the instructions to forward project the PET image data into SPECT projections based on the system parameters and the scan parameters and reconstruct the SPECT projections to generate the simulated SPECT data.
