    Abstract: Embodiments herein relate to systems and methods for rapidly calibrating optical medical sensors. In an embodiment, a method can include placing a reflective optical medical sensor device on or in a patient. The reflective optical medical sensor device can include one or more optical emitters; one or more optical detectors; and a measurement circuit having one or more transimpedance amplifiers (TIA). The method can include setting the TIA to a fixed gain value and then turning on the optical emitter associated with each spatially unique measurement vector and receiving reflected light with the associated optical detector for each spatially unique measurement vector at the same fixed gain value. The method can include assessing the signal-to-noise (SNR) for each spatially unique measurement vector and selecting the spatially unique measurement vector having the highest SNR. Other embodiments are also included herein.

    Abstract: A method for performing a medical procedure may comprise advancing a first device through a first body lumen. A distal portion of the first device may include a magnet. The method may further comprise advancing a second device through a second body lumen. The second device may include a magnetic field sensor. The method may further comprise receiving a signal from the magnetic field sensor. The signal may be indicative of a magnetic field measured by the magnetic field sensor. The method may further comprise, if the received signal matches a magnetic field of the magnet, identifying a position of the magnet.

    Abstract: A medical device that includes a sensor including a filter array. The sensor is configured to capture a raw image and the filter array is configured to filter the raw image into a frame of raw pixel values including first, second, and third pixel values. The medical device includes non-transitory computer readable medium storing demosaicing instructions that, when executed, causes a processor to exclude the first pixel values from the frame of raw pixel values. The processor generates estimated second pixel values at locations of the excluded first pixel values and the third pixel values on the frame, and generates estimated third pixel values at locations of the excluded first pixel values and the second pixel values on the frame. The processor creates a processed image having a partial-resolution frame from the second pixel values, estimated second pixel values, third pixel values, and estimated third pixel values.

    Abstract: The present disclosure includes devices, systems, and methods for reducing signal noise in endoscopic rotational imaging. Many embodiments include an elongate member that includes an impedance matching network disposed between a proximal imaging core and a distal imaging core. In many such embodiments, the elongate member may connect a controller at the proximal end and include a rotational transducer at the distal end. In various embodiments, the proximal and distal imaging cores may include a plurality of insulated conductors disposed within a shield (e.g., a shielded twisted pair (STP)). In various such embodiments, the insulated conductors may be utilized to communicate differential signals between the controller and the rotational imaging transducer. In some embodiments, the insulated conductors in the proximal imaging core may have a larger diameter than the insulated conductors in the distal imaging core.
