1. A method of probing a sample of living tissue including one or more calcifications, the method comprising:

  • directing incident radiation at a first surface of the sample;

    discriminating between backscattered elements, and forward scattered and transmitted elements of said incident radiation by said sample, and collecting said forward scattered and transmitted elements of said incident radiation from a second surface of the sample, the second surface being spaced from said first surface such that at least a portion of said tissue lies directly between said first and second surfaces; and

    detecting Raman radiation arising from Raman scattering by said one or more calcifications in the collected radiation.
