Treatment Time Calculation Table - Klas series

1) Energy loss is postulated to be linear at 7.5% per mm of tissue.
2) Treatment time is calculated by Monte Carlo Simulation method.

  Treatment Time (second) = Dose (J/cm3) x 1000 x Laser Spot Size (cm²)
—————————————————————————
End Power (mW) x Energy Loss Factor (/cm)
