Paper Abstract

Multiphoton tomography (MPT) has become a high-resolution label-free clinical imaging tool to obtain optical skin biopsies for rapid in vivo histology. Here, we report on the novel multimodal multiphoton tomograph MPT compact based on a chiller-free ultracompact 80 MHz femtosecond fiber laser operating at 780 nm. The 360°-measurement head contains the laser head and multiple photon detectors for (i) autofluorescence (AF) imaging, (ii) fluorescence lifetime imaging (FLIM) for optical metabolic imaging (OMI) and melanin detection, (iii) second harmonic imaging (SHG) of collagen, (iv) confocal reflection microscopy (CRM), and (v) white-light imaging (dermoscopy). Preliminary results of an ongoing multicenter clinical study in patients with suspicious pigmented lesions in two hospitals are presented.
