摘要： Methods and apparatus for coding a visual representation of one or more plaque regions in a vessel are provided. The method includes segmenting the visual representation of the vessel to identify structures associated with the vessel, classifying at least one region in the vessel as a plaque region, displaying the at least one plaque region using a visual highlight selectively associated with the classification for the at least one plaque region, and shading the visual highlight based on a probability that the classification is correct.

摘要： A method for producing an image of an object includes scanning an object with an imaging apparatus to collect projection data of the object utilizing cone sampling. The projection data is rebinned in a row-wise, fan-to-parallel fashion to produce rebinned data and the rebinned data is view-weighted to produce view-weighted data. The method further includes filtering the view-weighted data utilizing a row-wise ramp filter to produce filtered data and generating an image of the object utilizing the filtered data and a three-dimensional (3D) backprojection.

摘要： A method for memory reclamation is disclosed that includes marking a memory object when an attempt to alter a reference to the memory object is detected by a software write barrier. Marking be by using representations (“black,” “white”, “gray”) stored as part of a garbage collection information data structure associated with each memory object. Initially, all allocated memory objects are marked white. Objects are then processed such that objects referenced by pointers are marked gray. Each object marked gray is then processed to determine objects referenced by pointers in it, and such objects are marked gray. When all objects referenced by pointers in the selected gray objected have been processed, the selected gray object is marked black. When all processing has been completed, objects still marked white may be reclaimed. Also described is a garbage collector which runs as a task concurrently with other tasks. A priority of the garbage collector may be increased to prevent interruption during certain parts of the garbage collection procedure.
摘要翻译：公开了一种用于存储器回收的方法，其包括当通过软件写入屏障检测到改变对存储器对象的引用的尝试时，对存储对象进行标记。标记为使用与每个存储器对象相关联的垃圾收集信息数据结构的一部分存储的表示（“黑色”，“白色”，“灰色”）。最初，所有分配的内存对象都标记为白色。然后处理对象，使得由指针引用的对象被标记为灰色。然后处理标记为灰色的每个对象以确定由其中的指针引用的对象，并且这些对象被标记为灰色。当所选择的灰色对象中的指针引用的所有对象都已被处理时，所选的灰色对象被标记为黑色。所有处理完成后，仍可标记为白色的对象可能被回收。还描述了一个与其他任务同时作为任务运行的垃圾回收器。可以增加垃圾收集器的优先级，以防止在垃圾收集过程的某些部分期间的中断。

摘要： The present invention, in one form, is a system for performing image reconstruction from projection data acquired in a helical scan. More specifically, the system implements an incremental reconstruction algorithm for helical scan projection data which does not require filtering, weighting and backprojecting such projection data for generating each image. Particularly, a segmentation algorithm divides the projection into a plurality of segments so that subsequent images are generated by generating image data only for those segments that have changed from the base image.

摘要： A CT Fluoro system having an architecture and algorithms which facilitate increasing the frame rate and providing acceptable image quality is described. Generally, and in one embodiment, the system includes apparatus and algorithms that speed-up image reconstruction and reduce image artifacts that may result from such fast reconstruction. The fast reconstruction is achieved by performing, for example, view compression, channel compression, backprojection with reduced delay, and parallel processing.
