Decoupling channel count from field of view and spatial resolution in single-sensor imaging systems for fluorescence image-guided surgery.

ABSTRACT: SignificanceNear-infrared fluorescence image-guided surgery is often thought of as a spectral imaging problem where the channel count is the critical parameter, but it should also be thought of as a multiscale imaging problem where the field of view and spatial resolution are similarly important.AimConventional imaging systems based on division-of-focal-plane architectures suffer from a strict relationship between the channel count on one hand and the field of view and spatial resolution on the other, but bioinspired imaging systems that combine stacked photodiode image sensors and long-pass/short-pass filter arrays offer a weaker tradeoff.ApproachIn this paper, we explore how the relevant changes to the image sensor and associated image processing routines affect image fidelity during ima
