The Monte Carlo simulation code, SIMIND, describes a standard clinical SPECT camera and can easily be modified for almost any type of calculation or measurement encountered in SPECT imaging. SIMIND has been developed by Professor Michael Ljungberg, Medical Radiation Physics, Department of Clinical Sciences, Lund, Lund University, Sweden.

The entire code is written in FORTRAN and includes versions that are fully operational on Linux systems (x86), Mac systems running OSX, and on Windows (x86). The majority of the main code structure is similar for all of the operating systems; but, in cases where the operating system becomes unique, additional information on the code as it pertains to the specific system is provided.
