Abstract :
Iterative reconstruction techniques are usually too time consuming on most single processor machines that are affordable. This is especially true for the HRRT (High Resolution Research Tomograph) which produces huge sinogram data in order to take full advantage of its enhanced resolution. The use of Fourier Rebinning (FORE) in a preprocessing step is the basis for a simple cluster computing approach. The authors were able to scale down the reconstruction time with implementations utilizing RPC and Syngo mechanics, resp. on Windows NT networks
