摘要： The invention relates to the adaptation method (200) of adapting a geometric model to an image data comprising a region selection step (230) for selecting a region of the geometric model and a manual adaptation step (235) for manually adapting the geometric model to the image data using a set of characteristics of the region comprised in the geometric model. Using a region-specific characteristic from the set of characteristics of the selected region, such as a region-specific parameter determining the deformation range, for manually adapting the geometric model to the image data, requires relatively fewer user interactions.

摘要： The invention relates to a method (100) of adapting a geometric model to an image data comprising determining a first partial transformation for mapping a first part of the geometric model into the image data and a second partial transformation for mapping a second part of the geometric model into the image data. By determining the first partial transformation of the first part of the geometric model and the second partial transformation of the second part of the geometric model, the geometric model can assume more shapes and therefore can be more accurately adapted to an object comprised in the image data.

摘要： The invention relates to a system (100) for segmentation of image data describing an object comprising a first and second object component, the system comprising: a selection unit (120) for selecting a first component model of a plurality of first component models for adapting to the image data in order to delineate the first object component and for selecting a second component model of a plurality of second component models for adapting to the image data in order to delineate the second object component, a connection unit (130) for connecting the first and second component model, an initialization unit (140) for initializing the first and second component model in the image data volume, and an adaptation unit (150) for adapting the first and second component model to the image data, thereby segmenting the image data. Thus, the system (100) of the invention offers a good coverage of object variability, allowing many object models constructed from component models, while each component model is optimized to describe the modeled object component. Consequently, selecting an optimal first and second component model and an optimal way of connecting them improves the flexibility, robustness, and accuracy of the image data segmentation.

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： 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.
