Abstract: Techniques are disclosed for translating a virtual object within a displayed scene in a digital environment in a realistic and intuitive manner. The realistic and intuitive translation is achieved due to new techniques that are used for determining locations of the virtual object in the digital scene as the virtual object is being translated responsive to user input. In some embodiments, a control plane is constructed based upon a point of interaction with a virtual object and an initial surface in the scene on which the virtual object is located. The constructed control plane is then used to determine locations in the scene for locating and displaying the virtual object as the virtual object is translated from its start position to an end position in the scene.

Abstract: A 3D image processing system uses a three-dimensional dataset comprising voxels wherein said three-dimensional dataset is generated by performing imaging of a volume containing items. The image processing system performs segmentation of the three-dimensional dataset to generate segmented items. Each segmented item can be processed using a different image processing algorithm. For example, the skull can be processed using a first image processing algorithm (e.g., bone algorithm) and the brain can be processed using a second algorithm (e.g., soft tissue algorithm). A composite three-dimensional image is generated with the skull optimally displayed with the bone algorithm and the brain optimally displayed with the soft tissue algorithm. The composite images are displayed via 2D slice(s) to improve diagnosis.

Abstract: A method and apparatus of generating a modified segmented structure is disclosed. This adds voxels in proximity to a segmented structure to create a larger volume or area than the segmented structure. Analysis of these layers provides insight to the disease pathology of the segmented structure. Additionally, this layer can serve as a visual transition region between a segmented item on a checklist under inspection whose visual appearance is optimized and the remaining structures on the checklist whose visual appearance is subdued (e.g., darkened) to help the imager (e.g., radiologist) better focus on the image.

The method comprises collecting a plurality of copies of a two-dimensional image of the scene, generating an intermediate image by concatenating the plurality of copies of the two-dimensional image along a first direction, generating an intermediate depth map corresponding to the intermediate image by applying a neural network to the intermediate image, and generating, from the intermediate image and the intermediate depth map, the image of the scene with the corresponding depth map.

Abstract: A method and apparatus is disclosed, which significantly improves image quality. Specifically, the method disclosed utilizes structures within an image with a known or calculated value, such as a phantom or presumed homogeneous structure, such as an air mass outside of the patient. The method then performs segmentation of the imaging dataset and subsequent measurement of the structure with a known value. The difference between the known value and the measured value is used as a correction factor, which is then applied to the remainder of the dataset where values are not known. This can improve image quality by helping to generate extremely similar gray scale maps over multiple examinations and eliminate artifacts.

Abstract: A current screen is presented on a display of a user device, which includes an element distinct from a previous element of a previous screen, where the previous element occupied less than an entirety of the previous screen. The user device receives a gesture input that requests that the previous element be presented within the current screen next to a current element of the current screen. The gesture input indicates a location of the current element, wherein the location of the current element is less than an entirety of the current screen and is the same location at which the previous element was presented on the previous screen. The user device presents, on the display of the user device and responsive to receiving the gesture input, a contemporaneous view of the previous element next to the current element at the location of the current element within the current screen.
