In this thesis, a realistic and web accessible MRI simulator based on the solution of Bloch equation is proposed and implemented. The simulator generates images from virtually defined 3D objects using the pulse sequence and slice selection parameters provided by the user. The simulation is implemented in Java and the applications are developed as Java applets which are accessible through internet. The simulation software is composed of two applications: “Spin Simulator” and “MRI Simulator”. The “Spin Simulator” allows one to observe NMR phenomenon on 3D and 2D displays by applying excitation and relaxation to a virtual object. It is developed as an educational and supportive tool for “MRI Simulator”. The “MRI Simulator” generates slice images by executing the pulse sequence with the selected parameters on the 3D virtual object. Gradient echo and spin echo and echo planar pulse sequences are implemented and selectable by the user.
