    Abstract: Systems and methods related to combing multiple images are disclosed. An example method of combining multiple images obtained by an endoscope includes obtaining a first input image formed from a first plurality of pixels, wherein a first pixel of the plurality of pixels includes a first characteristic having a first value. The method also includes obtaining a second input image formed from a second plurality of pixels, wherein a second pixel of the second plurality of pixels includes a second characteristic having a second value. The method also includes subtracting the first value from the second value to generate a motion metric and generating a weighted metric map of the second input image using the motion metric.

    Abstract: Systems and methods related to estimating the distance of a body structure from a medical device are disclosed. An example method includes illuminating the body structure with a light source of a medical device, capturing a first input image of the body structure with a digital camera positioned on the medical device, representing the first image with a first plurality of pixels, wherein the first plurality of pixels includes one or more pixels displaying a local intensity maxima, defining a first pixel group from the one or more pixels displaying a local intensity maxima, wherein the first pixel group corresponds to a plurality of surface points of the body structure and wherein the first pixel group further includes a first image intensity. The method further includes calculating a relative distance from the digital camera to a first surface point of the plurality of surface points.

    Abstract: Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.

    Abstract: Medical devices and methods for using medical devices are disclosed. An example method for performing percutaneous nephrolithotomy includes registering an optical tracking system to a global coordinate system, registering a fluoroscope to the global coordinate system, generating a first image of a treatment area of a patient using the fluoroscope, generating a second image of the treatment area of the patient using the fluoroscope, selecting a target treatment point within the treatment area on the first image, the second image or both the first image and the second image and overlaying a medical instrument proposed guidance line on the first image, the second image or both the first image and the second image, wherein the medical instrument proposed guidance line depicts a proposed insertion pathway from an insertion point on the patient's body to the target treatment point.

    Abstract: Systems and methods related to combing multiple images are disclosed. An example method of combining multiple images of a body structure includes capturing a first input image with a digital camera positioned at a first location at a first time point, representing the first image with a first plurality of pixels, capturing a second input image with the digital camera positioned at a second location at a second time point, representing the second image with a second plurality of pixels, generating a first feature distance map of the first input image, generating a second feature distance map of the second input image, calculating the positional change of the digital camera between the first time point and the second time point and utilizing the first feature distance map, the second feature distance map and the positional change of the digital camera to generate a three-dimensional surface approximation the body structure.
