摘要： This invention describes an optimization and view dependency reduction method for multiplanar reformatting (MPR) of slice-based volume images. This method utilizes a traversal scheme that allows for efficient access of the computer memory layout of a sliced based volume, and therefore optimizes overall processing time. This method does not require changes to the volume memory layout or additional volume memory. Instead, efficient memory access is achieved by adaptive traversal patterns on the reformatting planes. The traversal pattern is adapted on-the-fly during rendering as the reformatting plane location and orientation is changed arbitrarily relative to the volume. In this way, the typical speed differences between various reformatting planes orientations caused by inefficient memory access is greatly reduced. Computer cache coherency, SIMD coherent implementation, and multiprocessing environments are also considered in the design of the traversal pattern.

摘要： Multiplanar reformatting visualization is provided with multiple scrolling speeds. A plurality of buffers is provided. Each buffer stores composites of data from different planes. The amount of compositing to generate a total composite for a visualization may be less since the division into partial composites may reduce addition and subtraction or other compositing operations. One level of partial composite buffers may be used. The total is recomputed for each visualization. In other embodiments, a hierarchal buffer structure is used. For example, a total composite buffer is provided in addition to the partial composite buffers. By re-compositing the partial composites before and after adjustment for scrolling increment from the total composite buffer, the total composite is updated for scrolling. Two or more levels of buffers may be used.

摘要： Technology for guiding a user to collect clinically usable ultrasound images is described. In some embodiments, an ultrasound device may automatically change the elevational steering angle of its ultrasound beam (e.g., using beamforming) in order to collect ultrasound data from different imaging planes within the subject. A processing device in operative communication with the ultrasound device may select one of the collected ultrasound images based on its quality (e.g., select the ultrasound image having the highest quality), and then continue to collect ultrasound images using the elevational steering angle at which the selected ultrasound image was collected.

摘要： The present disclosure is a handheld apparatus that vaporizes plant-based or synthetic compounds, for the purpose of inhalation, or diffusion into an external environment. More specifically, the disclosure describes a handheld apparatus wherein a laser beam from an internal laser unit heats compounds, such as dried plant, tinctures, resins, or essential oils, to the compound's vaporization temperature for inhalation, or diffused as part of aromatherapy or other holistic therapeutic treatments.

摘要： In order to prevent color bleeding, a method of volume rendering a three-dimensional (3D) dataset includes identifying, by a processor, a mask that defines a segmented volume within the 3D dataset. The processor identifies a position within the 3D dataset at or adjacent to a boundary defined by the mask, identifies a plurality of voxels within the 3D dataset that are adjacent to the identified position within the 3D dataset, and determine, for each voxel of the plurality of voxels, whether the respective voxel is inside or outside of the identified mask. The processor determines, for each voxel of the plurality of voxels, a weight for the respective voxel based on the determination of whether the respective voxel is inside or outside of the identified mask. The processor determines a voxel value for the identified position based on the determined weights and voxel values for the plurality of voxels, respectively.

摘要： A method of navigation in three-dimensional, electronic image data sets is disclosed, whereby the image data sets contain three-dimensional image data subsets. The method includes optically representing at least one two-dimensional projection of an image data set that includes a two-dimensional subprojection of at least one image data subset, optically highlighting the at least one two-dimensional subprojection, receiving a user input directed to the selection of a certain subprojection, and optically representing, in accordance with said user input, at least one additional two-dimensional projection of the image data set that includes a two-dimensional projection of the selected image data subset. The method can be used for an image data set that is formed by fusion of at least two source image data sets. The source image data sets can especially comprise computer tomography and a positron-emission tomography image data set.
