Abstract: Two dimensional position sensing system and sensors for use in such systems are disclosed. The sensors incorporate linear array sensors having sensor elements and an aperture plate. Some embodiments include a radiation source that directs radiation onto some of the sensor elements. Other embodiments including radiation blocking objects that block radiation from reaching some of sensor elements. The direction or position of the radiation source or radiation blocking object may be estimated from the radiation incident on the sensor elements.

Abstract: Two and three dimensional position sensing systems and sensors for use in such systems are disclosed. The sensors incorporate linear array sensors and an aperture plate to block light or other radiation from reaching most elements of the sensors. A direction of a radiation source relative is determined based on illuminated sensor elements in each sensor. The sensors are combined in systems to allow the position of a radiation source to be estimated.

Abstract: Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.

Abstract: Disclosed herein is a system and method for dynamic validation, correction of registration for surgical navigation during medical procedures on a patient which involves confirmation of registration between one or more previously registered virtual objects, such as surgical tools etc. in a common coordinate frame of a surgical navigation system and an operating room, and intra-operatively acquired imaging during the medical procedure in the common coordinate frame. The method includes displaying intra-operatively acquired imaging of the surgical field containing the one or more real objects corresponding to the one or more previously registered virtual objects, with the real objects being tracked by a tracking system.

Abstract: Systems, methods and devices are provided for illuminating tissue with monochromatic or broadband light and imaging light that has been reflected back from the tissue. Imaging may be white-light imaging or hyperspectral imaging. The system can be a stand-alone hyperspectral imaging system, integrated as part of an external video scope, or as an auxiliary imaging module on an external videoscope. Various elements of a video scope that is particularly suited for minimally invasive surgery is first presented and then its configurations suitable for hyperspectral imaging are explained.
