14-5 High-Efficiency Acquisition of Spherical Ray-Space

Abstract

High-efficiency acquisition of spherical ray-space is proposed. It uses the sinusoidal structure of EPI of spherical ray-space. Each EPI of spherical ray-space is transformed into an amplitude-phase domain image by integrating the value of EPI along sinusoidal waves with various amplitudes and phases. EPI is successfully reproduced from the amplitude-phase domain image by an iteration method.
