Mean intensity plot of the recorded video to specify laser-exposed frames. Laser-exposed frames were extracted from the video based on the brightness scale of frames. Peaks in the plot represent laser-exposed frames; however, some peaks with less than 30% of normal peak height were not counted as valid laser-exposed frames. These frames occurred when the laser was fired in the air, mostly during directional changes of the laser applicator when the SBS technique was simulated.
