Abstract :
Summary form only given. In order to attempt a clinical evaluation of an optical tomography (OT) system, the scanning time must be kept low. Two aspects of reducing scanning time are looked at in the work. The first aspect is based on experimentation using an existing system built around a ´rotate rotate´ geometry. The aim is to optimize this Mark I system in respect of the number of frequency domain measurements required in order to obtain a reasonably resolved two-dimensional (2D) image. A compromise has to be made between image quality and scanning time plus computation time spent on reconstruction. The second aspect is developing a faster Mark II OT system based on multiplexed fibre couplings between source tissue and detector.
