1. A method for monitoring tissue ablation comprising:

  • receiving light returned from a tissue; and

    generating a graph of at least one of a collagen peak indicative of an amount of collagen in the tissue and an NADH fluorescence peak indicative of an amount of myocardium in the tissue, wherein a wavelength of the collagen peak is indicative of a relative amount of collagen and myocardium in the tissue;

    displaying the graph representing the relative amount of collagen and myocardium in the tissue for the selection of an ablation strategy for a lesion formation in the tissue, the ablation strategy including the selection of one or more of an ablation energy type, an ablation energy power, duration of delivery of ablation energy, and ablation temperature limits of the ablation energy.
