摘要： The invention refers to a method of producing a medical report comprising a dynamic image information based on a volumetric scan of one or more internal organs of a subject. According to the method two-dimensional images for simulating a three-dimensional view of the one or more internal organs based on the volumetric scan are calculated using a workstation. The resulting two-dimensional images are next projected on a surface of a geometrical object, which is then unfolded to a two-dimensional flat plane (U,L,F,R,B,D), and stored in a generated textual medical report for further analysis on a low-end computer. Advantageously the stored two-dimensional images are displayed dynamically within the medical report, either as a sequence of images or as a part of a virtual environment.

摘要： A multi-dimensional data set assigns data values to positions in a multi-dimensional geometrical space. A visualization is derived from the multi-dimensional data set, for example, by way of a volume or surface rendering technique. The visualization is reproduced on a display and parts that have been missed in the display are detected and indicated. For example, a new representation is made on the basis of the detected missed parts, for example, from another point of view and/or another field of view.

摘要： A method of constructing an object data set of data elements representing a physical property is described, in which the construction of the object data set includes assigning attributes to respective data elements. Such attributes are used, for example, in volume rendering. The construction of the object data set is achieved in such a way that the relative contributions of the physical property to the values of the respective data elements are derived on the basis of the relative contributions of the physical property to the data values of the data elements. These contributions are calculated by modeling transition changes in the image using a plot of grey value and gradient magnitude. Sampling of data points along the maximum gradient allows identification of the ranges of the physical property contributing to the selected voxel and calculation of the relative amounts.

摘要： An apparatus 1000 includes an input 1010 for receiving an N-dimensional signal, N≧2. A storage 1030 stores a composite model of a composite structure for estimating parameters of the model with respect to the signal. The composite model is based on constituent models 210-290 that each correspond to a constituent structure in the signal and that are incorporated in the composite structure. Each constituent model is designated for estimating parameters of the constituent model with respect to the signal based on prior knowledge of the constituent structure. At least two of the constituent models are based on differing technologies. Each constituent model is provided with a uniform interface for controlling the constituent model and for retrieving parameters estimated by it. A processor 1020 is programmed to estimate the model parameters by controlling the constituent models to estimate their parameters; to retrieve estimated parameters from the constituent models; and to estimate parameters of the model in dependence on the retrieved parameters.
