摘要： Disclosed are systems, devices, and methods for marking a main carina and a trachea of a patient, an exemplary method comprising importing slice images of a chest of the patient, generating a three-dimensional (3D) model based on the imported slice images, displaying the 3D model in a graphical user interface (GUI), locating the main carina by viewing 2D images of the 3D model in an axial orientation, marking the main carina in one of the 2D images of the 3D model, adjusting a view plane of the 3D model around a rotation axis defined by the marked location of the main carina to adjust the view plane from an axial orientation to a coronal orientation while keeping the main carina in the view plane to thereby display the entire trachea on the GUI, and marking an upper end of the trachea in one of the 2D images of the 3D model.

摘要： A method for mapping a 3D surface that contains a volume in space, the method including: acquiring 3D vertices representing the surface, and defining in the space a first plane cutting the volume and a second parallel plane, external to the volume, thereby partitioning the vertices into a first set not between the two planes and a second set located between the two planes. The method further includes projecting the first set vertices onto the first plane so as to generate first projected points therein, and projecting the second set vertices onto the first plane while translating these vertices in respective directions parallel to the second plane by respective translations responsive to respective distances of the second vertices from the first plane, thereby generating second projected points in the first plane. The first and second projected points are displayed as a 2D representation of the surface on a screen.

摘要： Rendering of a dynamic workplane in a 3D rendering environment accessed through a two dimensional user interface is provided. The dynamic workplane is associated to a rendering tool in a rendering application for the 3D environment. The dynamic workplane orientation and position are dependent on the view perspective, the rendering tool selected and an interaction location in the 3D environment. The location and orientation of the dynamic workplane can change with each interaction by the user, each tool selected, and with changes in perspective relative to the 3D environment.

摘要： A method and device for determining an ego-motion of a vehicle. Respective sequences of consecutive images are obtained from a front view camera, a left side view camera, a right side view camera and a rear view camera and merged. A virtual projection of the images to a ground plane is provided using an affine projection. An optical flow is determined from the sequence of projected images, an ego-motion of the vehicle is determined from the optical flow and the ego-motion is used to predict a kinematic state of the car.

摘要： An intravascular ultrasound (IVUS) imaging system and catheter with an intuitive interface for rapid operator interaction using acquired medical images. In an embodiment, an IVUS imaging system and catheter are used to acquire a sequence of a specific area of interest in the human anatomy, for example, tomographic images of a coronary artery. The IVUS imaging system displays at least one tomographic image of the area of interest. The IVUS imaging system generates and displays at least one longitudinal image, wherein the longitudinal image represents a cut-plane of the sequence of tomographic images. The IVUS imaging system further includes a touch screen, wherein the system recognizes touch movements to facilitate searching the sequence of images. Touch movements in a longitudinal direction may pan the longitudinal image in the longitudinal direction. Touch movements in the transverse direction may rotate the cut-plane of the longitudinal image.

摘要： [Aim] To provide an image appropriate for observation of the course of blood vessels in a neighborhood of a cutting surface in a surgery assistance apparatus for assisting a surgery of excising an organ [Solution Means] An image generation means (70) that generates, from a three-dimensional image of an organ in which an excision region has been identified, an image representing the organ in such a manner that a blood vessel region in the organ is visually recognizable, a depth input receiving means (50) that receives an input specifying a depth of cutting, and a cutting surface setting means (60) that determines, as a cutting surface, a portion of a boundary surface within the specified depth of cutting along the boundary surface from an outer edge of the boundary surface toward an inside, and the boundary surface being between the excision region and a non-excision region, which is a region other than the excision region, in the organ, are provided. The image generation means (70) generates, from the three-dimensional image, the image representing the organ in such a manner that only a partial blood vessel region, which is present in a neighborhood region of the cutting surface in the blood vessel region of the organ, is visually recognizable.
