Abstract

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

First claim

What is claimed is:

1. A user wearable visualization system comprising:
a lighting assembly comprising:
a plurality of lighting elements arranged concentrically about a central axis, said central axis being substantially perpendicular to a plane of said plurality of lighting elements, wherein selected ones of said plurality of lighting elements concurrently emit a light within a known wavelength band, said concurrently emitted light forming an excitation light, said excitation light causing generation of an emission light; and

an eyewear comprising:
a plurality of lenses, each of said plurality of lenses comprising:
an emission filter configured to:
attenuate light in a first wavelength band of said excitation light; and
allow passage of said emission light.

2. The user wearable visualization system of claim 1 , wherein said known wavelength band is one of: a substantially same wavelength band and a different wavelength band.

3. The user wearable visualization system of claim 1 , wherein said known wavelength band is one of:
an ultra-violet light wavelength band, a colored light wavelength band and an Infra-red wavelength band.

4. The user wearable visualization system of claim 3 , wherein said colored light wavelength band is at least one of:
a violet wavelength band, a blue wavelength band, a cyan wavelength band, a green wavelength band, a yellow wavelength band, an orange wavelength band, and a red wavelength band.

5. The user wearable visualization system of claim 1 , wherein at least one of said selected ones of said plurality of said lighting elements comprises:
a transmission filter, wherein said transmission filter is configured to:
limit a wavelength range of said light emitted by a corresponding one of said at least one of said plurality of said selected lighting elements.

6. The user wearable visualization system of claim 5 , wherein said transmission filter is one of: a low pass filter passing light below a first known wavelength value and a bandpass filter passing light within a known bandpass wavelength.

7. The user wearable visualization system of claim 5 , wherein said limitation of said wavelength range is determined based on at least one characteristic of said light emitted by a corresponding one of said selected one of said plurality of lighting elements.

8. The user wearable visualization system of claim 5 , wherein said limitation of said transmission filter associated with a first one of said selected one of said plurality of said lighting elements is based on an intensity of said light emitted by a second one of said selected one of said plurality of lighting elements.

9. The user wearable visualization system of claim 1 , wherein said emission filter is one of: a long pass filter passing light above a second known wavelength value and a notch filter passing light outside a known wavelength band.

10. The user wearable visualization system of claim 9 , wherein said second wavelength value is based on a wavelength of said light emitted by said selected ones of said plurality of lighting elements and a wavelength value of said emission light.

11. The user wearable visualization system of claim 1 , wherein said plurality of lighting elements comprises:
a lighting source configured to:
emit a light within a white light wavelength band.

12. The user wearable visualization system of claim 1 , wherein each of said plurality of lenses comprises:
a magnification device.

13. The user wearable visualization system of claim 12 , wherein each of said magnification devices comprises:
a magnification device emission filter, wherein said magnification device emission filter is one of: a long pass filter passing light above a known wavelength value and a notch filter passing light outside a known wavelength band.

14. The user wearable visualization system of claim 1 , wherein said emission filter is removably attached to said eyewear.

15. The user wearable visualization system of claim 1 , wherein an intensity of said light emitted by a first one of said selected ones of said lighting elements is greater than an intensity of said light emitted by a second one of said selected ones of said lighting elements.

16. The user wearable visualization system of claim 1 , wherein said excitation light comprises:
a first wavelength emitted within a lower range of a blue wavelength band; and
a second wavelength emitted in an upper range of said blue wavelength band.
