O'Connor, M.E., Bentall, R.H.C. and Monahan, J.C.), Springer-Verlag, pp. 103-123. Electromagnetic diagnostic and treatment devices exert direct and indirect effects on tissue metabolism. Electromagnetic devices produce spatially inhomogeneous deposition of energy in tissues and, therefore, affect tissue metabolism heterogeneously. Optical spectroscopy provides unique approaches to monitoring tissue metabolic status during medical treatment. Methods are being developed that provide both area and depth resolved metabolic measurements. This emerging technology provides high contrast images of tissue metabolism, perfusion and oxygenation for use in monitoring effects of electromagnetic radiation on tissues.
