1. A medical tissue investigation method comprising the steps of:

  • generating electromagnetic energy having a predetermined first frequency;

    transmitting electromagnetic energy of said first frequency along a predetermined first line extending through a patient;

    also generating electromagnetic energy having a predetermined second frequency different from said first frequency;

    transmitting electromagnetic energy of said second frequency along a predetermined second line extending through the patient at a predetermined angle relative to said first line, said second line intersecting said first line at one predetermined point inside the patient, said steps of transmitting being performed simultaneously;

    automatically detecting electromagnetic radiation emitted from organic cellular material at said predetermined point in response to excitation of said cellular material by electromagnetic energy of said first frequency and electromagnetic energy of said second frequency upon simultaneous irradiation of said predetermined point by electromagnetic energy of said first frequency and electromagnetic energy of said second frequency; and

    automatically determining a spectral output of said organic cellular material from electromagnetic radiation received from said predetermined point through the patient during said step of detecting.
