Method of processing a broadband elastic scattering spectrum obtained from tissue

摘要

An elastic scattering spectrum taken from human tissue is taken and preprocessed by dividing the absorption spectrum into a plurality of wavelength ranges and fitting the measured absorption spectrum to the absorption of predetermined absorption components in some fitting ranges and to a smooth function, such as a straight line, in the remainder of the fitting ranges. The absorption components may include, for example, haemoglobin.
