Title:
BIOLOGICAL TISSUE IMAGING APPARATUS FOR SURGICAL OPERATION AND BIOLOGICAL TISSUE IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/031014
Kind Code:
A1
Abstract:
[Problem] To more accurately imagize information about a biological tissue in a non-invasive manner even when the biological tissue is not birefringent. [Solution] This biological tissue imaging apparatus for surgical operation is provided with: an illumination device capable of emitting polarized light beams in a predetermined polarization state at a biological tissue under multiple illumination conditions so as to effect differences among the state of the polarized light beams directed at the same imaging site; an imaging device for distinguishing and imaging light reflected from the biological tissue as a result of the polarized light beams emitted under the multiple illumination conditions, and generating multiple polarized light images which are images of the biological tissue captured using the polarized light; and a structure information image generation unit which uses the polarized light images obtained from the same imaging site of the biological tissue and generates a structure information image which expresses the inner structure at the imaging site of the biological tissue. The structure information image generation unit generates a difference image using the obtained multiple polarized light images, and provides the difference image as the structure information image.
