Method for tuning patient-specific cardiovascular simulations

Номер: US20120259608A1
Автор: Charles Anthony Taylor, JR., Ryan Leonard Spilker
Принадлежит: Leland Stanford Junior University

Computational methods are used to create cardiovascular simulations having desired hemodynamic features. Cardiovascular modeling methods produce descriptions of blood flow and pressure in the heart and vascular networks. Numerical methods optimize and solve nonlinear equations to find parameter values that result in desired hemodynamic characteristics including related flow and pressure at various locations in the cardiovascular system, movements of soft tissues, and changes for different physiological states. The modeling methods employ simplified models to approximate the behavior of more complex models with the goal of to reducing computational expense. The user describes the desired features of the final cardiovascular simulation and provides minimal input, and the system automates the search for the final patient-specific cardiovascular model.

A global composition system is described. In one or more implementations, the global composition system may be configured to perform rendering for a plurality of applications. For example, the global composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the applications. The APIs may then be used to cause a single composition engine to perform the rendering for the plurality of applications. The use of a single composition engine may be used to support a variety of different functionality, such as to perform efficient rendering by knowing what elements are provided by each of the applications and how those items relate for rendering to a display device.

Boundary Handling for Particle-Based Simulation

Номер: US20120330628A1
Автор: Richard Gary McDaniel, Zakiya Tamimi
Принадлежит: Siemens Corp

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.

System and method for animating collision-free sequences of motions for objects placed across a surface

Номер: US20130033501A1
Автор: Michael Girard, Susan AMKRAUT
Принадлежит: Autodesk Inc

Embodiments of the invention set forth a technique for animating objects placed across a surface of a graphics object. A CAD application receives a set of motions and initially applies a different motion in the set of motions to each object placed across the surface of the graphics object. The CAD application calculates bounding areas of each object according to the current motion applied thereto, which are subsequently used by the CAD application to identify collisions that are occurring or will occur between the objects. Identified collisions are cured by identifying valid motions in the set of motions that can be applied to a colliding object and then calculating bounding areas for the valid motions to select a valid motion that, when applied to the object, does not cause the object to collide with any other objects.

Computing the mass of an object

Номер: US20130163836A1

Принадлежит: STMICROELECTRONICS SRL

The mass of an object may be estimated based on intersection points of a representation of a surface in an image space with cubes defining the image space, the surface representing a surface of an object. The representation may be, for example, based on marching cubes. The mass may be estimated by estimating a mass contribution of a first set of cubes contained entirely within the representation of the surface, estimating a mass contribution of a second set of cubes having intersection points with the representation of the surface, and summing the estimated mass contribution of the first set of cubes and the estimated mass contribution of the second set of cubes. The object may be segmented from other portions of an image prior to estimating the mass of the object.

SIMD Group Formation Techniques for Primitive Testing associated with Ray Intersect Traversal

Disclosed techniques relate to primitive testing associated with ray intersection processing for ray tracing. In some embodiments, shader circuitry executes a first SIMD group that includes a ray intersect instruction for a set of rays. Ray intersect circuitry traverses, in response to the ray intersect instruction, multiple nodes in a spatially organized acceleration data structure (ADS). In response to reaching a node of the ADS that indicates one or more primitives, the apparatus forms a second SIMD group that executes one or more instructions to determine whether a set of rays that have reached the node intersect the one or more primitives. The shader circuitry may execute the first SIMD group to shade one or more primitives that are indicated as intersected based on results of execution of the second SIMD group. Thus, disclosed techniques may use both dedicated ray intersect circuitry and dynamically formed SIMD groups executed by shader processors to detect ray intersection.

The present invention discloses a digital pathological section scanning system and relates to the field of a section scanning technology. The system comprises a scanning end, an image processing end, a remote server, a first client end and a second client end; wherein, the scanning end scans a pathological section to form an original pathological section image and transmits the original pathological section image to the image processing end for processing; the image processing end processes the original pathological section image to form a digital pathological section image and sends the digital pathological section image to the remote server; the first client end transmits medical record information including attending physician information to the remote server; the remote server associates the digital pathologic section image with the attending physician information and saves the digital pathological section image in the storage unit corresponding to the attending physician information.
