The multimodal probe arranges 8 innovative photonic modules (optodes) around the US transducer, providing capability for optical tomographic reconstruction. For more accurate estimate of lesion composition, US-assessed morphological priors can be used to guide the optical reconstructions. Each optode comprises: i) 8 picosecond pulsed laser diodes with different wavelengths, covering a wide spectral range (635-1064 nm) for good probing of the different tissue constituents; ii) a large-area (variable, up to 8.6 mm2) fast-gated digital Silicon Photomultiplier; iii) the acquisition electronics to record the distribution of time-of-flight of the re-emitted photons. The optode is the basic element of the optical part of the system, but is also a stand-alone, ultra-compact (about 4 cm3) device for time domain multi-wavelength diffuse optics, with potential application in various fields. date: 2021-01-01 date_type: published publisher: SPIE official_url: https://doi.org/10.1117/12.2576778 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1872398 doi: 10.1117/12.2576778 isbn_13: 9781510641136 lyricists_name: Arridge, Simon lyricists_id: SRARR14 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Progress in Biomedical Optics and Imaging - Proceedings of SPIE volume: 11639 place_of_pub: Online Only pagerange: 116390C event_title: SPIE BiOS issn: 1605-7422 book_title: Proceedings of Optical Tomography and Spectroscopy of Tissue XIV citation: Pifferi, A; Dalla Mora, A; Di Sieno, L; Ferocino, E; Tosi, A; Conca, E; Sesta, V; ...
