Figure Lengend Snippet: (A) Schematic of the imaging-projection unit of Overlay Tissue Imaging System (OTIS). The unit comprises (i) a 785 nm diode laser, (ii) a near infrared autofluorescence (NIRAF) image collection unit – a near infrared (NIR) camera with focusing and long pass filter optics, (iii) a data processing laptop and (iv) a visible light projection unit. A color camera is additionally integrated to capture the projected image. (B) The imaging-projection unit is attached to ball mount which in turn is connected to a double articulated arm supported by a portable cart. A disposable sterile handle (green) is inserted into a slot designed on the arm, which permits the surgeon to conveniently position the imaging unit at any angle above the surgical field. CMOS, complementary metal oxide semiconductor.
