High-speed image reconstruction by parallel computing in time resolved optical computer tomography using FDTD (finite difference time domain) analysis of pulse responses in scattering media

摘要

High speed processing for optical parameters image reconstruction by parallel computing in time resolved optical computer tomography has been studied. The image reconstruction is based on FDTD analysis, which requires much time for iteratively computing spatial and time dependencies of the field components. The image reconstruction times have been decreased to 1/n with respect to the number n of CPUs in a shared memory parallel computing machine with static time schedulings. The numerical calculation errors remain within 10{sup}(-13) in the parallel computing.
