Paper Abstract

Cylindrical light diffusion is a key element in a variety of medical applications which require the controlled administration of light to a treatment site within the body. Applications such as photodynamic therapy (PDT), laser induced hyperthermia (LHT), and photoatherolytic (PAL) therapy may all require that light be diffused in this manner. Cylindrical diffusers are typically used in tubular cavities, such as the bronchus, trachea, or the esophagus, and in interstitial applications where uniform illumination over a specified length is required to maximize the therapeutic response. A third generation of cylindrical diffuser with improved performance has been developed to more effectively meet these needs. This paper will discuss the evolution of cylinder diffusers and will describe the characteristics and performance of this new generation device.
