Abstract

A system having a plurality of light sources that emit light focused to treat an internal treatment site at a location determined using an imaging device that is integrally mounted in a housing with the plurality of light sources. The imaging device may include, for example, either an ultrasonic transducer or a gamma probe that produces a signal suitable for displaying an image of the internal treatment site. The image thus displayed enables the location, shape, extent, and depth of the internal treatment site to be determined so that an operator can correctly position the housing in which the imaging device and light sources are disposed. Each light source is provided with either a conventional refractive lens or a totally internally reflective (TIR) lens that directs and focuses the light at the appropriate depth within a patient's body. In addition to locating the internal treatment site, the imaging device can be employed to monitor the status of the treatment site during the course of light therapy and thus enables modification of the therapy as appropriate to adjust for changes in the shape and size of the internal treatment site.
