Abstract
The present invention includes apparatus and method to prevent surgical injury. The invention incorporates near infrared (NIR) spectroscopy, which capitalizes on near infrared light's ability to penetrate deeply into tissues and spectroscopic capability to discern tissue's chemical properties. The present invention further characterized the NIR optical properties of bile containing structures as a clinically useful probe.
Claims16
An apparatus to visualizes one or more tissues in vivo comprising:
- an electromagnetic radiation source capable of producing a continuous wave broadband light;
- at least one optical probe connected to the electromagnetic radiation source;
- a multi-channel CCD array spectrometer detector connected to the optical probe capable of collecting near infrared wavelength emissions;
- at least one computer connected to the multi-channel CCD array spectrometer detector, wherein the computer comprises one or more image evaluation algorithms;
- and
- at least one display connected to the computer to generate images from the one or more tissues and display results from the image evaluation algorithms.
A method for imaging one or more tissues in a subject during a surgical operation comprising the steps of:
- directing a continuous wave broadband light towards the one or more tissues using at least one optical probe;
- collecting near infrared wavelength emissions from the one or more tissues using the optical probe;
- analyzing the near infrared wavelength emissions using one or more image evaluation algorithms;
- and
- reconstructing a two-dimensional or three-dimensional optical map of the one or more tissues based on results derived from the one or more image evaluation algorithms.
