    摘要: A method allowing display of time-varying merged high resolution and low resolution image data with a smooth frame rate. In one embodiment the high resolution data is structural image data and the low resolution image data is functional image data. The functional image data is gathered (20) into groups and each group is rendered and merged (24) together. The merged images produced are then stored (28) in a First In First Out (FIFO) buffer for display. While the merged images are displayed the next set of functional image data is merged and rendered and supplied to the FIFO buffer, allowing a smooth frame rate to be achieved. A computer program and a medical imaging apparatus using the method are also disclosed.

    摘要: A system for establishing a contour of a structure is disclosed. An initialization subsystem (1) is used for initializing an adaptive mesh representing an approximate contour of the structure, the structure being represented at least partly by a first image, and the structure being represented at least partly by a second image. A deforming subsystem (2) is used for deforming the adaptive mesh, based on feature information of the first image and feature information of the second image. The deforming subsystem comprises a force-establishing subsystem (3) for establishing a force acting on at least part of the adaptive mesh, in dependence on the feature information of the first image and the feature information of the second image. A transform-establishing subsystem (4) is used for establishing a coordinate transform reflecting a registration mismatch between the first image, the second image, and the adaptive mesh.

    摘要: Diagnostic angiograms only provide the projected lumen of a coronary, which is only an indirect measure of blood flow and pressure decline. According to an exemplary embodiment of the present invention, a motion compensated determination of a flow dynamics and a pressure decline for stenosis grading is provided, in which the motion compensation is performed on the basis of a tracking of a first position of a first marker and a second position of a second marker in the projection data set. This may provide for a robust and precise flow dynamics and pressure decline determination.

    摘要: Method and system for facilitating post-processing of images using deformable meshes in which a deformable mesh model of an object such as an organ is extended by attaching information thereon in order to simplify and/or facilitate a desired post-processing task so that the post-processing task effected when the mesh is applied to the same object in an additional image can expeditiously use this information. The information may be attached to the mesh after its creation, for example, upon segmentation of the same object in some training image. The post-processing task can therefore be performed automatically without user interaction upon segmentation of the object in the additional image. Information is encoded on the mesh by enumerating a list of triangles or vertices of the mesh which have to be considered in the subsequent, post-processing task and by optionally providing additional parameters defining the precise post-processing algorithm(s) to be used.

    摘要: A system (900), method (100, 200) and apparatus (600, 700, 800) are provided for analyzing a blood flow in a vascular system from a dynamic diagnostic observation sequence (101) to determine blood flow parameters (112) for further determination of filters, replay speed and finally visualization of the replayed original and filtered sequences. A first embodiment (100) extracts features of the observation and uses these features to select an appropriate model from a database of pre-determined models of vascular system of interest which have associated parameters. These parameters are varied to create an instance of the model that best matches the original observation. A second embodiment (200) visualizes a replay of the original observation (101) and the observation (101′) predicted by the model to highlight differences therebetween. A third embodiment (800) provides filtering and control of the replay speed.

    摘要: The invention relates to a method and a system for the simultaneous reconstruction of the three-dimensional vessel geometry and the flow characteristics in a vessel system. According to one realization of the method, vessel segments (41) of a parametric models are fitted to differently oriented X-ray projections (Pl, Pk, PN) of the vessel system that are generated during the passage of a bolus of contrast agent, wherein the fitting takes the imaged contrast agent dynamics and physiological a priori knowledge into account. In an alternative embodiment, the vessel geometry is reconstructed progressively along each vessel, wherein a new segment of a vessel is added based on the continuity of the vessel direction, vessel radius and reconstructed contrast agent dynamics.

    摘要: The present invention relates to a way of storing 3D images. The 3D image is composed of a stack of two-dimensional video data subsets represented by arrays of pixel data. Each array of pixel data is partitioned into a plurality of overlapping and adjacent vertical stripes of pixel data having a width at most equal to a cacheline of the memory. The upper most left stripe is stored first and each stripe is stored after the left adjacent stripe. When storing each stripe having multiple rows of pixel data, the upper row is stored first and the first pixel data of each subsequent row of the stripe is stored in a memory location coming after a memory location where the last pixel data of the preceding row in the stripe is stored.
