  • Patent number: 11555874
    Abstract: A system for displaying and interacting with magnetic resonance imaging (MRI) data acquired using an MRI system includes an image reconstruction module configured to receive the MRI data and to reconstruct a plurality of images using the MRI data, an image rendering module coupled to the image reconstruction module and configured to generate at least one multidimensional image based on the plurality of images and a user interface device coupled to the image rendering module and located proximate to a workstation of the MRI system. The user interface device is configured to display the at least one multidimensional image in real-time and to facilitate interaction by a user with the multidimensional image in a virtual reality or augmented reality environment.

  • Patent number: 11100696
    Abstract: Systems, methods, and media for rendering voxel-based 3D content are provided. In some embodiments, a system for rendering voxel-based content comprises: a display; and hardware processor programmed to: receive voxel-based data representing an object at multiple different resolutions; perform, for a representation including low-resolution voxels, a first forward-projection ray marching operation with a step size based on the voxel volume; identify a voxel that causes a threshold to be exceeded; perform, for a second representation including higher-resolution voxels each smaller in volume than the first voxels, a second forward-projection ray marching operation; identify a second voxel in the second representation that causes the threshold to be exceeded; determine that the second representation is a highest resolution available; and cause a pixel to present a portion of the object based on a value associated with the second voxel.
