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.

Method of multiple image reconstruction and registration

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.

Measurement markings in distal tip imaging field of view

An endoscopic system includes an endoscopic imager configured to capture image frames of a target site within a living body and a processor configured to apply a spatial transform to a preliminary set of image frames, the spatial transform converting the image frames into cylindrical coordinates; calculate a map image from the spatially transformed image frames, each pixel position in the map image being defined with a vector of fixed dimension; align a current image frame with the map image and apply the spatial transform to the current image frame; fuse the spatially transformed current image frame to the map image to generate a fused image; and apply an inverse spatial transform to the fused image to generate an enhanced current image frame having a greater spatial resolution than the current image frame. The system also includes a display displaying the enhanced current image frame.

System and method for endoscopic video enhancement, quantitation and surgical guidance

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.

Method of robust surface and depth estimation

An endoscopic system includes an endoscopic imager configured to capture images of a target site within a living body and a processor configured to determine one or more image metrics for each one of a plurality of image frames captured over a time span, analyze changes in the image metrics over the time span, and determine a turbidity metric for the target site based on the analyzed changes in the image metrics.

System, device and method for turbidity analysis

A system for assisting a surgeon in placing at least one ablation device into a treatment region of a patient, where the system includes at least one computer system having a display, a user interface and software, is described. The system uses patient image data of the treatment region to generate an image of the treatment region on the display and identifies the treatment region to ablate with a target. Tissue properties of the treatment region are identified and used to perform thermal modeling. Treatment parameters are generated and an ablation zone is calculated. A computer system display is generated showing (a) the number of ablation devices required to ablate the treatment region and the location and orientation of each ablation device in the treatment region and (b) the ablation zone.

System and methods for ablation treatment planning and intraoperative position updates of ablation devices

A system and associated methods to determine an optimal radiation beam arrangement are provided. The system includes a computer planning apparatus which includes a treatment plan optimization computer having a memory and an input device in communication with the treatment plan optimization computer to provide user access to control functions of plan optimization software. An image gathering device is in communication with the treatment plan optimization computer through a communications network to provide an image slice of the tumor target volume and the non-target structure volume. The plan optimization software computationally obtains and then optimizes a proposed radiation beam arrangement iteratively based on constraints to form an optimized radiation beam arrangement. A conformal radiation therapy delivery device in communication with the treatment plan optimization computer through the communications network then applies the optimized radiation beam arrangement to the patient.
