Methods and systems of identifying oral cancer in vivo are disclosed. An oral cavity of a patient is illuminated with a plurality of illuminating photons. A plurality of interacted photos are received from the oral cavity. The interacted photons may have been absorbed, reflected, scattered or emitted by the oral cavity. The interacted photons are filtered into first and second polarized multi-passband wavelengths using first and second tunable conformal filters, respectively. A detector captures the first and second polarized multi-passband wavelengths. A processor automatically discriminates between cancerous tissue and non-cancerous tissue in an image resolved from the first and second polarized multi-passband wavelengths.

An endoscope system includes an endoscope, a video processor, and a parameter control device. The parameter control device causes the endoscope and the video processor to execute predetermined processing by controlling a plurality of parameters used in the endoscope and the video processor. The parameter control device includes a data collection unit, a determination unit, and a parameter determination unit. The determination unit determines contents of constraint processing by determining a plurality of pieces of information acquired by the data collection unit, and determines contents of recovery processing so that a function for displaying an endoscope image is recovered, the function being degraded through the constraint processing. The parameter determination unit determines one or more parameters used in the constraint processing and one or more parameters used in the recovery processing.

Systems and methods of imaging include projecting infrared (IR) light from the endoscope toward the at least one anatomical feature (e.g., the exterior of a liver or lung), capturing the IR light, projecting optical light from the endoscope toward a similar portion of the anatomical feature, and capturing the optical light. Once the IR light and the optical light are captured, both are associated with one another to generate an intra-operative 3D image. This projection and capture of IR and optical light may occur at discrete times during the imaging process, or simultaneously.

The surgical instrument includes first and second jaws and a flexible circuit including multiple sensors to optimize performance of a radio frequency (RF) device. The flexible circuit includes at least one therapeutic electrode couplable to a source of RF energy, at least two sensing electrodes, and at least one insulative layer. The insulative layer is positioned between the at least one therapeutic electrode and the at least two sensing electrodes. The method includes contacting tissue positioned between the first and second jaws of the surgical instrument with the at least one therapeutic electrode and at the least two sensing electrodes; sensing signals from the at least two sensing electrodes; and controlling RF energy delivered to the at least one therapeutic electrode based on the sensed signals.

The shaft is configured for insertion through a cut in a body of a patient, whereas the shaft includes a working vacuum channel running therethrough. The camera is fitted at a distal end of the shaft and is configured to provide images of a target tissue site in the body. The hollow cutting tool is for insertion over a guidewire in the working vacuum channel of the shaft, whereas the hollow cutting tool is configured to pierce the target tissue site under guidance of images taken by the camera. The inflatable balloon is configured to stabilize the distal end of the shaft, whereas the inflatable balloon is located proximally to the camera so as not to obstruct the images of the target tissue site.
