Title:
IMAGING APPARATUS FOR DISPLAYING CONCENTRATION RATIOS
Document Type and Number:
WIPO Patent Application WO2001015597
Kind Code:
B1
Abstract:
Imaging apparatus for representing an image of concentration ratios between a first and a second substance in a region of interest of an object, with different measuring values being represented with different colors and/or gray shades. The apparatus comprises a light source capable of irradiating the object with light, which light comprises at least three wavelengths lambda 1, lambda 2 and lambda 3, lambda 3 being an isobestic wavelength, lambda 1 being a wavelength at which the first substance has a lower absorption than the second substance, and lambda 2 being a wavelength at which the first substance has a higher absorption than the second substance. The apparatus further comprises detection means comprising a matrix of pixel detectors, for representing a virtually instantaneous image of the region of interest.
