Confirmation of IVPA temperature monitoring during heating of SiO₂AuNR on a human right coronary artery ex-vivo. (A) The percent IVPA signal change versus relative baseline temperature are plotted in the absence of CW laser heating (black), and following CW laser heating of the SiO₂AuNR inclusion using output energies of 60 mW (orange) and 200 mW (blue) from the integrated IVUS/IVPA imaging catheter. (B) FLIR thermal images and temporal profiles of surface temperature rise of the SiO₂AuNR inclusion exposed to 200 mW (top) and 60 mW (middle) CW laser heating and a control region of the artery exposed to 200 mW CW laser heating (bottom).
