Abstract
An apparatus is disclosed for displaying a tissue containing a fluorescent dye at least in sections. It is proposed for the purpose of simplification to record the tissue with a number of cameras from different observation angles while omitting a beam splitter, and subsequently to produce a joint superimposed overall image.
Claims20
An apparatus for displaying a tissue containing a fluorescent dye at least in sections, comprising:
- a first image acquisition device, arranged at a first observation angle with respect to the tissue, to acquire a first fluorescent image by illuminating the tissue with a light in a near infrared region utilized for exciting a fluorescent dye and a first native tissue image formed by ambient light;
- a second image acquisition device, arranged at a second observation angle with respect to the tissue differing from the first observation angle, to acquire a second fluorescent image and a second native tissue image;
- and
- an image generating device to generate,
- a joint fluorescent image reconstructed from the first and the second fluorescent images and including a common observation angle with respect to the tissue, and
- a joint tissue image reconstructed from the first and the second native tissue images and including the common observation angle with respect to the tissue, and
- the image generating device configured to superimpose at least one of the first native tissue image, the second native tissue image and the joint tissue image with at least one of the first fluorescent image, the second fluorescent image and the joint fluorescent image to produce an overall image reproducing the tissue from a uniform observation angle with respect to the tissue.

An apparatus for displaying a tissue containing a fluorescent dye at least in sections, comprising:
- first image acquisition means, arranged at a first observation angle with respect to the tissue, for acquiring a first fluorescent image by illuminating the tissue with a light in the near infrared region utilized for exciting a fluorescent dye and a first native tissue image formed by ambient light;
- second image acquisition means, arranged at a second observation angle with respect to the tissue differing from the first observation angle, for acquiring a second fluorescent image and a second native tissue image;
- and
- an image generating means for generating,
- a joint fluorescent image reconstructed from the first and the second fluorescent images and including a common observation angle with respect to the tissue, and
- a joint tissue image reconstructed from the first and the second native tissue images and including the common observation angle with respect to the tissue,
- the image generating means further for superimposing at least one of the native first tissue image, the native second tissue image and the joint tissue image from at least one of the first fluorescent image, second fluorescent image and the joint fluorescent image to produce an overall image reproducing the tissue from a uniform observation angle with respect to the tissue.
