Abstract: Systems and methods for target movement modelling use sequences of position data from a first electromagnetic (EM) sensor disposed at a distal portion of a catheter disposed in a lung and from at least one second EM sensor disposed at the patient's chest in order to update target tissue position. The methods involve generating a breathing model of the lungs as a function of breathing phases based on the position data from the first and second EM sensors. The methods also involve receiving current position data from the at least one second EM sensor and estimating a current breathing phase based on the breathing model and the current position data. The methods also involve predicting displacement of the target based on the breathing model and the current breathing phase, and updating body coordinates near the target based on the displacement of the target.

Abstract: A system and method of image processing including a processor in communication with a display and a computer readable recording medium having instructions executed by the processor to read an image data set from the memory, segment the image data set, and skeletonize the segmented image data set. The instructions cause the processor to graph the skeletonized image data set, assign a branch identification (ID) for each branch in the graph, and associate each voxel of the segmented image data set with a branch ID. The instructions cause the processor to generate a three-dimensional (3D) mesh model from the graphed skeletonized image data set, associate each vertex of the 3D mesh model with a branch ID; and display in a user interface the 3D mesh model, and an image of the image data set.

Abstract: Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include determining a level of zoom of a fluoroscope when acquiring a reference frame. The methods further include determining whether the live fluoroscopic images evidence movement of the fluoroscope relative to its position when capturing a reference frame.

Abstract: Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

Abstract: Systems and methods of image processing include a processor in communication with a display and a computer readable recording medium having instructions executed by the processor to read a three-dimensional (3D) image data set from the computer-readable recording medium and automatically generate a tree structure of blood vessels based on patient images of the image data set using a neural network. Manually- and/or semi-automatically-generated 3D models of blood vessels are used to train the neural network. The systems and methods involve segmenting and classifying blood vessels in the 3D image data set using the trained neural network, closing holes, finding roots and endpoints in the segmentation, finding shortest paths between the roots and endpoints, selecting most probable paths, combining most probable paths into directed graphs, solving overlaps between directed graphs, and creating 3D models of blood vessels based on the directed graphs.
