PETstep is a fast analytic PET simulator designed in MATLAB environment for high throughput simulation of PET images. It allows a full simulation of a user defined activity distributions (objects) or the insertion of realistic user defined tumors into existing patients. PETstep is designed as a plugin for CERR (Computational Environment for Radiological Research). Both patient and objects must be in DICOM format loaded in CERR.
dPETstep is a fast dynamic PET simulator designed in MATLAB environment for high throughput simulation of dynamic PET images. It allows full simulation of a user defined parametric image, kinetic model, input function, time sampling and more into realistic (noisy) dynamic PET-like images. Furthermore, the dynamic PET data can then be model fitted to produce parameter/parametric image estimates. dPETstep is designed as an extension of PETstep. Currently, Matlab functions from PETstep are used by dPETstep, but there is no requirement of CERR.
