Propagation of highly scattered radiation in tissue
- 148 Downloads
An increasing number of biomedical technologies for sensor applications and photodynamic therapy are based on the propagation of highly scattered radiation in tissue. A simple example of a sensor is the Pulse Oximeter where light from a Light-Emitting Diode (LED) is directed onto a finger (see Figure 12.1), and the measured attenuation determines whether the blood is oxygen rich or oxygen poor.
