Abstract
Near-infrared imaging is being examined clinically as a diagnostic tool to image hemoglobin concentration and oxygen saturation within tissue. Optical projection measurements can be detected from tissue surfaces and combined with an appropriately designed diffusion model-based image reconstruction algorithm to recover maps of the tissue interior. One important issue in the development of this modality is that the geometry of source and detector fibers has a significant impact of the resulting images. In this paper we examine the tradeoffs between using a full circular array of measurements versus a partial array of measurements, as often described in the fan beam imaging approach. Case examples are presented to qualitatively illustrate the possible improvement in going from a circular geometry to the fan-beam geometry of detectors.
