Dual-modality rigid endoscope for photoacoustic imaging and white light videoscopy.

ABSTRACT:

Significance

There has been significant interest in the development of miniature photoacoustic imaging probes for a variety of clinical uses, including the in situ assessment of tumors and minimally invasive surgical guidance. Most of the previously implemented probes are either side viewing or operate in the optical-resolution microscopy mode in which the imaging depth is limited to ∼1  mm. We describe a forward-viewing photoacoustic probe that operates in tomography mode and simultaneously provides white light video images.

Aim

We aim to develop a dual-modality endoscope capable of performing high-resolution PAT imaging and traditional white light videoscopy simultaneously in the forward-viewing configuration.

Approach

We used a Fabry-Pérot ultrasound sensor
