The main part of the thesis has been to implement an environment in Matlab, suitable for simulating diffusion MRI. The implementation consists of a simulation of self-diffusion, wall detection and interaction for the diffusing particles, and of applying a gradient to generate the MRI-signal. The part of the implementation that needed the most consideration was the part including the possibility of using obstacles with arbitrary shapes. The diffusion and wall interaction parts of the program has been tested out quite thorough and seems to work satisfying. The diffusion MRI signal is also tested, but should probably be investigated to some higher extent before trusting the results completely.
