    Abstract: Quantification of metric or functional parameters often requires image segmentation. A crucial part of such method is the model of the surface characteristics of the object of interest (features), which drives the deformable surface towards the object boundary in the image. According to the present invention, sections of the mesh are assigned to different classes for different features. According to the present invention, the assignment of mesh sections to the classes is adapted by using actual feature information from the unseen image. Advantageously, this allows for an adaptation of the feature category to which the mesh section is assigned and thereby allows an improved segmentation of the object.

    Abstract: The invention relates to a method of segmenting a three-dimensional structure from a three-dimensional, and in particular medical, data set while making allowance for user corrections. The method is performed with the help of a deformable three-dimensional model whose surface is formed by a network of nodes and mashes that connect these nodes. Once the model has been positioned at the point in the three-dimensional data set at which the structure to be segmented is situated and positions of nodes have, if necessary, been changed by known methods of segmentation, any desired nodes can be displaced manually. The nodes of the model are re-calculated by making weighted allowance for the nodes that have been displaced manually.

    Abstract: The invention relates to a method for data processing. At stage 3 the position of the reference object in the reference image and its relation to a set of reference landmarks in the reference image is established at step 6. In order to enable this, the reference imaging of learning examples may be performed at step 2 and each reference image may be analyzed at step 4, the results may be stored in a suitably arranged database. In order to process the image under consideration, the image is accessed at step 11, the suitable landmark corresponding to the reference landmark in the reference image is identified at step 13 and the spatial relationship established at step 6 is applied to the landmark thereby providing the initial position of the object in the actual image. In case when for the object an imaging volume is selected, the method 1 according to the invention follows to step 7, whereby the scanning 17 is performed within the boundaries given by the thus established scanning volume. In case when for the object a model representative of the target is selected, the method 1 follows to the image segmentation step 19, whereby a suitable segmentation is performed. In case when for the model a deformable model is selected, the segmentation is performed by deforming the model thereby providing spatial boundaries of the target area. The invention further relates to an apparatus and a computer program for image processing.

    Abstract translation: 本发明涉及一种数据处理方法。 在阶段3,在步骤6中建立参考图像中的参考对象的位置及其与参考图像中的一组参考标记的关系。为了实现这一点,可以在步骤2执行学习示例的参考成像 并且可以在步骤4分析每个参考图像,结果可以存储在适当布置的数据库中。 为了处理所考虑的图像,在步骤11访问图像,在步骤13识别与参考图像中的参考标记相对应的合适地标,并将在步骤6建立的空间关系应用于地标,从而提供 物体在实际图像中的初始位置。 在对于物体选择成像体积的情况下,根据本发明的方法1遵循步骤7,由此在由这样建立的扫描体积给出的边界内执行扫描17。 在针对对象的情况下,选择了表示目标的模型,则对图像分割步骤19进行方法1,由此执行适当的分割。 在为模型选择可变形模型的情况下,通过使模型变形从而提供目标区域的空间边界来执行分割。 本发明还涉及一种用于图像处理的装置和计算机程序。
