Abstract: Systems and methods for processing electronic images from a medical device comprise receiving a first image frame and a second image frame from a medical device, and determining a region of interest by subtracting the first image frame from the second image frame, the region of interest corresponding to a visual obstruction in the first image frame and/or second image frame. Image processing may be applied to the first image frame and/or second image frame based on a comparison between a first area of the first image frame corresponding to the region of interest and a second area of the second image frame corresponding to the region of interest, and the first image frame and/or second image frame may be provided for display to a user.

Abstract: Methods and devices are provided for determining anatomical distance and/or position measurements during an endoscopic procedure. Markings are placed either physically or superimposed on a distal end of an elongate tool, such that the markings are viewable in an imaging field of view of the endoscope. Anatomic distances may be determined by measurements performed with the tool. The size and/or position of anatomical structures or unknown objects may also be determined using the marked tool.

Abstract: Systems and methods for processing electronic images from a medical device comprise receiving an image frame from the medical device, and determining a first color channel and a second color channel m the image frame. A location of an electromagnetic beam halo may be identified by comparing the first color channel and second color channel. Edges of an electromagnetic beam may be determined based on the electromagnetic beam halo, and size metrics of the electromagnetic beam may be determined based on the edges of the electromagnetic beam. A visual indicator on the image frame may be displayed based on the size metrics of the electromagnetic beam.

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.

Abstract: A system is disclosed that includes an optical fiber including a first optical module and a gate. The gate can be capable of moving between closed and opened states to form a slit. At least one storage medium can be included having encoded thereon executable instructions that, when executed by the at least one processor, cause the system to carry out a method including directing light from the first optical module through the slit onto the stone to form a pair of lines with a spacing between the pair of lines; and determining a size of the stone, based on a distance from a distal tip of the optical fiber and the spacing between the pair of lines.

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: 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.
