Supplementary Material

Supplementary Video 1: Complete cross-sectional fly-through of the volumetric OCT images obtained immediately after the RFA treatment. Hyperscattering features of burned tissue on top of the ablated area and hyposcattering features of typical BE glands at the edge of the ablated area can be observed.

Supplementary Video 2: Complete cross-sectional fly-through of the volumetric OCT images obtained immediately after the CSA treatment. The spongiform appearance due to the edematous tissue caused by freezing can be observed in the data set.
