Figure 2: Dot and band burns patterns: effects of density. Effects of dot and band laser burn density on ischemia progression. Dot pattern burn (first subfigure rows (a) and (b)) with (a) and (b) and their effectiveness on prevention of ischemia progression (second to fourth subfigures in each row). Label indicates that the initial sum ablated area of these dot pattern burns is equivalent to that with two band pattern burns. Label means that the edge of the dot pattern burn is 100 microns. Band pattern burns (first subfigure rows (c) and (d)) with (c) and (d) and their effectiveness on prevention of ischemia progression (second to fourth subfigures in each row). Label means that number of laser burns is 2. Label “, ” means that band pattern burn has length of 300 microns and width of 100 microns. Color bar for oxygen maps has unit mmHg. Warmer color in oxygen maps represents higher oxygen tension.
