1. A method for determining a location of material within tissue comprising;
- irradiating tissue with radiation, the tissue having material located underneath a surface of the tissue;
collecting inelastically scattered radiation from the material at a plurality of at least three locations on different sides of the tissue and defining a plane extending through the tissue; and
determining the location of the material within the tissue.

Abstract
The present invention relates to the use of inelastically scattered light, particularly fluorescent and Raman scattered light, for determining the location and composition of material within various organs of the human body. The systems and methods of the present invention provide for medical imaging in three dimensions as well as histological information that can be used for diagnosing disease and various medical conditions.

8. A method for determining a location of material within tissue comprising;
-
providing a laser that emits light at an excitation wavelength; providing a plurality of optical collectors around the tissue and a detector, the collectors being optically coupled to the detector; irradiating tissue with radiation at the excitation wavelength, the tissue having a lesion located underneath a surface of the tissue; collecting inelastically scattered radiation from the lesion at least at three locations on different sides of the tissue, the three locations defining a plane extending through the tissue; and detecting with the detector the collected light; generating a three dimensional representation of the lesion with the detected light; and determining the location of the lesion within the tissue. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
