Abstract
Embodiments related to medical imaging devices including rigid imaging tips and their methods of use for identifying abnormal tissue within a surgical bed are disclosed.
Claims38
A method for identifying abnormal tissue, the method comprising:
- providing a first light comprising a first excitation wavelength to a surgical bed;
- collecting a fluorescence signal from the surgical bed using a photosensitive detector;
- comparing the fluorescence signal to an abnormal tissue threshold to identify abnormal tissue;
- and
- indicating one or more locations of the identified abnormal tissue on a screen.
2 more elements
A method for identifying abnormal tissue, the method comprising:
- illuminating a surgical bed with a first light comprising a first excitation wavelength of an imaging agent;
- illuminating the surgical bed with a second light comprising a second wavelength different from the first excitation wavelength;
- and
- collecting a signal from the surgical bed using a photosensitive detector.
1 more element
A method for identifying abnormal tissue, the method comprising:
- illuminating the surgical bed with ambient light;
- and
- illuminating a surgical bed with a first light comprising a first excitation wavelength of an imaging agent by pulsing a first illumination source;
- collecting a first signal from the surgical bed corresponding to ambient light using a photosensitive detector including a plurality of pixels;
- and
- collecting a second signal from the surgical bed corresponding to ambient light and a pulse of the first illumination source.
