A medical image processing apparatus includes a port, a processor and a display. The port acquires volume data. The processor sets a three-dimensional region in the volume data, acquires three vectors orthogonal to each other from the three-dimensional region, calculates three surfaces to which the vectors are normal lines, and generates three cross-sectional images of the volume data by setting the respective surfaces as cross-sections. The display shows the generated cross-sectional images. The processor shifts at least one surface in parallel along the corresponding normal line and regenerates a cross-sectional image in which the shifted surface is a cross-section.

The objects present in a particular computer generated 3d environment are represented to a user as distributed amongst a plurality of display area. The relative positions of the objects are maintained, and whenever an object is removed from one display area it is added to another. The point of view presented to the user may be the same for each display area, with all being controlled together, or separate control may be provided for each area or sub-group of areas.

The present invention relates to a device for displaying image information, the device comprising: a detection unit (10), which is configured to identify a plurality of admissible display orientations of multiple data sets; a restriction unit (20), which is configured to restrict the plurality of admissible display orientations of at least one of the multiple data sets to a set of admissible display orientations in common for all the multiple data sets; and/or to restrict a plurality of admissible scrolling directions of at least one of the multiple data sets to a set of admissible scrolling directions that are normal to the restricted admissible display orientations; and a display unit (30), which is configured to display the multiple data sets using the set of the restricted display orientations and/or the set of restricted scrolling directions.

Describe is a method for visually presenting, or previewing, changes to 3-dimensional geometry. In Onshape, a user may apply a sequence of configurable geometric operations in order to design a 3-dimensional model. When a user edits a specific operation, the method provides a way for the user to see the effects changes will have on a model. The method provides high-fidelity visualizations of the user's design as it would be before the operation is applied, after the operation is applied, and the operation's effects in conjunction with the effects of all operations in the sequence. The method also provides an interface for transitioning between these visualized states, allowing the user to effectively and efficiently understand the effect of the changes.

An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.

A system aligns a 3D model of an environment with image frames of the environment and generates a visualization interface that displays a portion of the 3D model and a corresponding image frame. The system receives LIDAR data collected in the environment and generates a 3D model based on the LIDAR data. For each image frame, the system aligns the image frame with the 3D model. After aligning the image frames with the 3D model, when the system presents a portion of the 3D model in an interface, it also presents an image frame that corresponds to the portion of the 3D model.

In some implementations, a method includes: obtaining a request to display a virtual object at a location within a computer-generated environment; and, in response to detecting the request to display the virtual object the location within the computer-generated environment: determining a real-world pose for the electronic device relative to a first coordinate space associated with a physical environment; determining a viewing vector by transforming the real-world pose from the first coordinate space to a second coordinate space associated with the computer-generated environment; in accordance with a determination that the viewing vector satisfies viewing criteria, displaying the virtual object at the location within the computer-generated environment according to a first view mode; and in accordance with a determination that the viewing vector satisfies second viewing criteria, displaying the virtual object at the location within the computer-generated environment according to a second view mode.

Obtaining a surface image captured by an endoscope inserted in a tubular organ associated with a surrounding blood vessel and representing an inner surface of a wall of the organ, generating, from a three-dimensional image representing a three-dimensional area including the organ, an adjacent blood vessel image depicting a portion of the blood vessel adjacent to the wall from a viewpoint in the three-dimensional image corresponding the viewpoint of the surface image, generating, from a three-dimensional image representing a three-dimensional area including a surrounding area of the organ, a surrounding blood vessel image depicting the blood vessel from a viewpoint in the three-dimensional image corresponding the viewpoint of the surface image, and causing the surface image, adjacent blood vessel image, and surrounding blood vessel image to be displayed in this order on a display unit.

A system and method for planning surgical procedure including a treatment zone setting view presenting at least one slice of a 3D reconstruction generated from CT image data including a target. The treatment zone setting view presenting a treatment zone marker defining a location and a size of a treatment zone and configured to adjust the treatment zone marker in response to a received user input. The system and method further including a volumetric view presenting a 3D volume derived from the 3D reconstruction and a 3D representation of the treatment zone marker relative to structures depicted in the 3D volume.

Systems and methods present multiple images of a three-dimensional model, including a three-dimensional representation of an anatomic structure and a representation of a medical device relative to the anatomic structure, on a graphical user interface. The multiple images correspond to different views (e.g., in multiple, different planes) of the three-dimensional model to provide complementary spatial information regarding a position of the medical device relative to the anatomic structure during a medical procedure performed on the anatomic structure. Such complementary spatial information can, for example, provide spatial context to facilitate controlling the position of the medical device relative to the anatomic structure during the medical procedure.
