Effect of Laser Irradiation at Different Wavelengths (940, 808, and 658 nm) on Pressure Ulcer Healing: Results from a Clinical Study
Figure 2
Ulcer area measured using an infrared camera. Example of the healing process of a chronic pressure ulcer under treatment with laser therapy (thermographic image and temperature profile across the ulcer; the difference between warmer/cooler pixels in the wound area was used to calculate the ulcer area).
