Treatment Time Calculation Table - Megalas-AM-800
Treatment time for tissue in depth is calculated by Monte Carlo Simulation method.
Energy loss is postulated to be linear at 7.5% per mm of tissue.
Energy Loss Factor = 1 x (1 - 0.075)n       n = Depth of Tissue in mm
Treatment Time (second) = Dose (J/cm3) x 1000 x Laser Beam Spot Size (cm²)
