IMAGING SYSTEM FOR FLUORESCENCE GUIDED SURGERY BASED ON FIXED MAGNIFICATION LENS AND DIGITAL ZOOM
First Claim
1. An imaging system comprising:
- a visible light source configured to illuminate a surgical field with visible light;
an excitation source configured to generate excitation light to excite a fluorescent substance in an organism within the surgical field;
a first sensor configured to receive visible light reflected from the surgical field via a first spectral channel;
a second sensor configured to receive a fluorescent emission emitted from the fluorescent substance in the organism via a second spectral channel;
a plurality of fixed magnification lenses configured to optically couple image signals to the first sensor and the second sensor; and
a control unit configured to receive and digitally process the image signals to generate a plurality of image frames in order to rescale the plurality of image frames for display to a surgeon.

Abstract
The invention relates to an imaging system for use in operating rooms and other applications. According to one example, the imaging system may include a visible light source configured to illuminate a surgical field with visible light and an excitation source configured to generate excitation light to excite a fluorescent substance in an organism within the surgical field. The imaging system may also include an imaging lens system including a first sensor configured to receive visible light reflected from the surgical field via a first spectral channel and a second sensor configured to receive a fluorescent emission emitted from the fluorescent substance in the organism via a second spectral channel. The imaging system may further include a plurality of fixed magnification lenses configured to optically couple image signals to the first sensor and the second sensor, and a control unit configured to receive and digitally process the image signals to generate a plurality of image frames in order to rescale the plurality of image frames for display to a surgeon.
