Claim 12:
13. An apparatus for mapping boundaries of a tumor embedded in non-tumorous biological tissue comprising:
a dye laser system including a dye laser and a laser amplification cavity having an intracavity quenching chamber containing a mixture of sample non-tumorous biological tissue and probe ions being of a single type of ion, wherein each probe ion included in the probe ions has an absorption bandwidth that does not exceed a narrowness threshold bandwidth amount and whose absorption wavelength peak shifts based on a local binding environment, the dye laser system configured to emit a dye laser beam within a body of a living being, the sample non-tumorous biological tissue being initially in the body and in a proximity to a tumor in the body, and the sample non-tumorous biological tissue being extracted from the body and placed in the dye laser system;
an injection system for injecting a solution of probe ions in a concentration matching a concentration of the probe ions in the mixture contained in the intracavity quenching chamber, the injection system configured to inject the solution in front of the dye laser beam emitted by the dye laser system to bind a first portion of the probe ions in the solution to the tumor in the body and a second portion of the probe ions in the solution to non-tumorous biological tissue in the body, and the dye laser beam emitted from the dye laser system having wavelengths exciting the probe ions bound to the tumor to generate an emission of radiation, but not exciting the probe ions bound to the non-tumorous biological tissue in the body; and
a detector for detecting the emission of radiation generated by the probe ions bound to the tumor for identifying boundaries of the tumor.
