Abstract
An interoperative light therapy apparatus and method are disclosed. The apparatus includes an excitation light source, a plurality of light emitting devices and a plurality of light detecting fibers, wherein the plurality of light emitting devices produce a fluorescence light in cancerous cells of a patient treated with a photosensitizing medication. The fluorescence light is collected by the plurality of detector fibers and a digital spatial image of the cancerous cells is produced. The digital spatial image is useful for targeting the cancerous cells in a subsequent resection procedure. An interoperative light therapy apparatus is disclosed that further include a therapy light source that can deliver therapy light to the cancerous cells using the digital spatial image in the subsequent resection procedure.
