STIR: an Open Source library for PET and SPECT image reconstructionMS76

STIR is Open Source software providing a Multi-Platform Object-Oriented framework for all data manipulations in tomographic imaging. Currently, the emphasis is on image reconstruction in emission tomography (PET and SPECT). Motion correction and parametric imaging is also supported. STIR is implemented in C++ but provides both a Python and MATLAB interface. STIR has an active developer community contributing new features. It can be downloaded from
