ABSTRACT:
A method for producing a detecting phosphorescent emission from a body portion comprising the following steps: inserting phosphorescent material into the body portion; inserting a needle into said body portion, said needle encasing a light guide for propagating a light signal therethrough, said light signal exciting said phosphorescent material within said body portion so as to produce a phosphorescent emission having a radius of visibility; and collecting the phosphorescent emission using a collector placed proximate to the surface of the body portion. The present invention also encompasses apparatus for inserting an excitation light into a tissue sample comprising: a needle having a light guide extending axially within the needle, the light guide being configured to transmit an excitation light into the body portion, so as to a phosphorescent carrier medium within the tissue sample.
