摘要： The present invention relates to image processing devices and related methods. The image processing device (10) comprises a data input (11) for receiving spectral computed tomography volumetric image data organized in voxels. The image data comprises a contrast-enhanced volumetric image of a cardiac region in a subject's body and a baseline volumetric image of that cardiac region, e.g. a virtual non-contrast image, wherein the contrast-enhanced volumetric image conveys anatomical information regarding coronary artery anatomy of the subject. The device comprises a flow simulator (12) for generating, or receiving as input, a three-dimensional coronary tree model based on the volumetric image data and for simulating a coronary flow based on the three-dimensional coronary tree model. The device comprises a perfusion synthesis unit (13) for generating a perfusion image representative of a blood distribution in tissue at at least one instant in time taking at least the baseline volumetric image and said coronary flow simulation into account.

摘要： A fluid flow is simulated by causing a computer to perform operations on data stored in the memory to compute at least one eddy of a fluid flow at a first scale (410) and perform operations to compute at least one eddy of the fluid flow at both the first scale (410) and a second scale (420). The second scale is a finer scale than the first scale, and the computation of the at least one eddy of the fluid flow is constrained by results of the computation of the at least one eddy of the fluid flow at the first scale (420)

摘要： Boundary handling is performed in particle-based simulation. Slab cut ball processing defines the boundary volumes for interaction with particles in particle-based simulation. The slab cut balls are used for collision detection of a solid object with particles. The solid object may be divided into a plurality of independent slab cut balls for efficient collision detection without a bounding volume hierarchy. The division of the solid object may be handled in repeating binary division operations. Processing speed may be further increased by determining the orientation of each slab cut ball based on the enclosed parts of the boundary rather than testing multiple possible orientations.

摘要： A system for determining rim shape includes a memory and a processor in communication with the memory. The processor is configured to receive one or more specifications for a rim. The processor is also configured to determine a rim depth for the rim based at least in part on the one or more specifications and a pareto front of rim shapes. The processor is also configured to determine a curvature control ratio and an endpoint tangency angle for the rim based at least in part on the rim depth. The processor is further configured to generate a rim shape for the rim based at least in part on the rim depth, the curvature control ratio, and the endpoint tangency angle.
