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: This disclosure teaches determining a renal calculus size based on calibration data generated from an endoscopic imager. During a lithotripsy procedure, images are received by a deployed endoscopic probe. Based on the received imaging data, the generated calibration data, and known properties of the endoscopic probe, one or more renal calculi in the images are identified and sized. The determined size values are displayed with the images of the renal calculi.

Abstract: A medical system includes a shaft having a proximal end and a distal end, an imaging device at the distal end of the shaft, and a controller, the controller receives image data comprising pixel data from the imaging device, the pixel data including a plurality of individual pixel values, converts the pixel data from a RGB format to a YCbCr format, and forms adjusted pixel data by applying a gain to the pixel data, wherein the gain is based on a Y value, a Cb value, and a Cr value of the individual pixel values of the converted pixel data.

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.
