Simulation is a very important tool in medical imaging, as I already wrote in a previous post. In nuclear medicine, Monte-Carlo simulation is the most used method to simulate data. There are several Monte-Carlo packages, which vary in precision and accuracy of the simulated effects and computational demand. Some research groups devised their own Monte-Carlo computer codes, built on top of a general-purpose code, which serves as core layer and application-specific modules are constructed in a hierarchical layer architecture.
PET-EGS based on EGS4 (Electron Gamma Shower 4) http://irs.inms.nrc.ca/research/imaging/
GATE (Geant4 Application for Tomographic Emission) http://www.opengatecollaboration.org/
Dedicated packages that have supported PET and/or SPECT research are:
SimSET (Simulation System for Emission Tomography)http://depts.washington.edu/simset/html/user_guide/user_guide_index.html
SORTEO (Simulation Of Realistic Tridimensional Emitting Objects) http://sorteo.cermep.fr/
PeneloPET (PENetration and Energy LOss of PET) http://nuclear.fis.ucm.es/penelopet/
GATE is one of the most famous packages and the paper published by the authors is here:

Do you recommend other packages?

Simulation MRI - free tools
Simulation is essential when working on medical imaging from the technique development point of view. Therefore, tools to do MRI simulation are described here. All of these tools have scientific papers published which you can cite in your work.
Brainweb http://brainweb.bic.mni.mcgill.ca/brainweb/
This tools works mostly as a database of brain MRI's with specific sequences and artifacts, but several parameters can be manipulated to obtain custom made simulations.
JEMRIS http://www.jemris.org/
This tool allows to define the phantom and the sequence, therefore it is one of the most flexible tools available. The reconstruction of non-linear sequences is not available.
MRI Simulation and Reconstruction http://bigwww.epfl.ch/algorithms/mri-reconstruction/
This package was developed in Matlab and allows to simulate and reconstruct datasets.
SIMRI http://www.simri.org/
This package is able to simulate several advanced artifacts and sequences, although the package itself does not seem very intuitive.
FSL POSSUM http://fsl.fmrib.ox.ac.uk/fsl/fsl-4.1.9/possum/index.html
This is a part of the well-know MRI/fMRI software FSL, which allows simulation of MRI images with some artifacts.
Do you know other MRI simulators? Please share.
