Calibration-Free Quantitative SPECT Imaging of Alpha Emitters Using Torch Recon®: Monte Carlo-Based Reconstruction Model
Quantitative SPECT imaging of the alpha-emitters Ac-225 and Pb-212 is fundamentally limited by a low count rate and high-energy photon emissions that produce collimator penetration, septal scatter, and detector backscatter within clinically used photopeak win...

Improved Lu-177 SPECT Statistical Efficiency Using Torch Recon® Multi-Energy Monte Carlo Reconstruction
Quantitative Lu-177 SPECT imaging requires balancing statistical precision with clinically feasible acquisition times. Conventional reconstruction relies on triple-energy-window (TEW) scatter correction and is therefore effectively limited to the 208 keV phot...
