  • Endoscopic imaging system for diseased tissue
    Patent number: 5769792
    Abstract: Apparatus for imaging diseases in tissue comprising a light source for generating excitation light that includes wavelengths capable of generating characteristic autofluorescence for abnormal and normal tissue. A fiber-optic illuminating light guide is used to illuminate tissue with light that includes at least the excitation light thereby exciting the tissue to emit the characteristic autofluorescence. An imaging bundle collects emitted autofluorescence light from the tissue. The autofluorescence light is filtered into spectral bands in which the autofluorescence intensity for abnormal tissue is substantially different from normal tissue and the autofluorescence intensity for abnormal tissue is substantially similar to normal tissue. An optical system is used to intercept the filtered autofluorescence light to acquire at least two filtered emitted autofluorescence images of the tissue.
    Type: Grant
    Filed: April 15, 1996
    Date of Patent: June 23, 1998
    Assignee: Xillix Technologies Corp.
    Inventors: Branko Palcic, Calum E. MacAulay, Bruno W. Jaggi, Stephen C-T Lam, Amedeus E. Profio, Jaclyn Y-C Hung
