1. An apparatus for analyzing optical radiation of a vessel, comprising:

  • at least one fiber having a proximal and a distal end, said fiber being capable of transmitting optical radiation and capable of placement of said distal end proximate to a locus on a wall of said vessel;

    a balloon encasing said distal end of at least one said fiber and capable of transmitting optical radiation from said locus or a vessel wall portion into said fiber distal end, when inflated and in contact with said locus or vessel wall portion during use of said apparatus;

    a detector optically connected to said at least one fiber proximal end and comprising means for digitizing an optical signal received from said fiber proximal end; and

    a computer capable of receiving said digitized signal and mathematically fitting said digitized signal to a curve selected from a spectrum of curves for black body radiations held at preselected temperatures, to ascertain the temperature of said locus or wall portion.
