Quantitative evaluation of overall A/V quality included comparison of treatment console images versus the physician's shared screen images using cross-correlation image registration metrics. Image lag was tested similarly, using cross-correlation over time to establish when the frame recorded on the physician's computer matched the secondary sharing computer's image frame. The time for the physician's computer to match the secondary computer was the image lag. With regards to subjective A/V quality, physicians, physicists, and therapists were all surveyed after each SBRT fraction, asking each group to rate A/V quality using a Likert scale ( Figure 2 ).
