Development of a handheld fluorescence imaging camera for intraoperative sentinel lymph node mapping

J Biomed Opt. 2015 May;20(5):051025. doi: 10.1117/1.JBO.20.5.051025.

Abstract

We present a compact fluorescence imaging system developed for real-time sentinel lymph node mapping. The device uses two near-infrared wavelengths to record fluorescence and anatomical images with a single charge-coupled device camera. Experiments on lymph node and tissue phantoms confirmed that the amount of dye in superficial lymph nodes can be better estimated due to the absorption correction procedure integrated in our device. Because of the camera head's small size and low weight, all accessible regions of tissue can be reached without the need for any adjustments.
