The PERSPECT methodology for generating the SPECT system matrix  is now available through the official OPENGATE documentation, in the "Teaching Resources and Examples" section

https://opengate-python.readthedocs.io/en/master/user_guide/user_guide_resources.html

The PERSPECT project will be presented at the 2026 IEEE Nuclear Science Symposium and Medical Imaging Conference (IEEE NSS/MIC 2026) with the following contributions:

• “Hamiltonian Monte Carlo Ensemble Features for DATSCAN SPECT Analysis in Parkinson's Disease”
• “Physics-Enriched Projection Matrices for Iterative Emission Tomography”
