摘要： A reconstruction unit is provided for receiving a sequence of data sets, the data sets representing structural information of the object. The reconstruction unit performs receiving scheduling information related to the data sets of the sequence of data sets. Then reconstructing a sequence of coarse reconstructions of the object by using the sequence of data sets and the scheduling information. Afterwards a sequence of adapted models of the object is generated by adapting a respective model to each of the coarse reconstructions. Then a motion of a predetermined portion of each of the adapted models is determined and a specific data set of the sequence of data sets is selected, wherein the specific data set corresponds to the adapted model with the minimum motion of the predetermined portion. Finally the reconstruction unit performs reconstructing a fine reconstruction of at least the part of the object using the specific data set.

摘要： The invention relates to a system (100) for producing a representation of an object in image data, based on a template coupled to a model of the object, the system comprising a model unit for adapting the model to the object in the image data, and a template unit for adapting the template to the adapted model on the basis of the coupling between the template and the model. The template defines a representation of the object which is simpler to interpret than the model. The template may be arranged to emphasize useful features of the object. The template comprises substantially fewer degrees of freedom and thus can be efficiently adapted to the model. Because the template of the invention is coupled to the model, the position, orientation and/or shape of the template is determined by the model adapted to the object in the image data. Hence, the template is adapted to the image data. The adapted template is capable of representing the object and its individual characteristics, e.g., the shape of the object as well as the position and/or orientation of the object with respect to an external reference system defined, e.g., based on the image data.

摘要： The present invention relates to a method for performing computer-aided detection (CAD) of a disease, e.g. lung tumours, on a medical image data set (20) from a imaging modality, such as MRI or CT. Initially, there is perform a segmentation of the medical image data set (20) using an anatomical model. Secondly, the segmented data is analyzed for characteristics of the disease resulting in a set of analysis data (25), and finally the set of analysis data (25) is evaluating with respect to the disease. At least one of these steps comprises as an input a position dependent probability (P_r) for the disease. The invention isadvantageous in that more efficient computations can be performed because the degree ofanalysis in a certain region of the part of the patient, e.g. the lung, can be adjusted or tailored to the level of probability of the disease in the that region. It is thereby possible to increase computational speed and thereby diseases like cancer, in particular cancer nodules in the lungs, can be more effectively found from medical image analysis.

摘要： A computer program product is described to adapt a shape model to a patient data set, the data set representing at least a region of anatomy of the patient, and in which the shape model is pre-adapted to a data set representing substantially the same anatomy of the same patient. This provides a surprisingly better segmentation of the data in the data set. In addition, A computer program product is described for the comparison of quantitative patient data and arranged to access quantitative patient data contained in a patient data record, characterized in that the quantitative patient data is in the form of an adapted shape model, adapted from a pre-adapted shape model. This extends the improvement derived by use of pre-adapted shape models and extends them to the use of pre-adapted shape models for data comparison.

摘要： A method and apparatus for interactively manipulating a shape of an object, comprising selecting an object to be manipulated and rendering the object in dependence of a manipulation type. The method provides a smart object adapted interaction, manipulation and visualization scheme in contrast to previous display driven schemes. The method allows efficient shape manipulation by restricting the degrees of freedom for the manipulation to the meaningful ones for a given object or object part, thus allowing to reduce e.g. a 3D interaction to a 2D interaction.

摘要： The invention relates to a system (100) for propagating a model mesh based on a first mean model mesh and on a second mean model mesh, the system comprising: a registration unit (110) for computing a registration transformation for registering the first model mesh with the first mean model mesh; a forward transformation unit (120) for transforming the model mesh into a registered model mesh using the registration transformation; a computation unit (130) for computing a propagation field for propagating the registered model mesh, the propagation field comprising vectors of displacements of vertices of the second mean model mesh relative to respective vertices of the first mean model mesh; a propagation unit (140) for transforming the registered model mesh into the propagated registered model mesh based on applying the vertex displacement vectors comprised in the propagation field to respective vertices of the registered model mesh; and an inverse transformation unit (150) for transforming the propagated registered model mesh into the propagated model mesh using the inverse of the registration transformation, thereby propagating the model mesh. Using the propagation field comprising vectors of displacements of vertices of the second mean model mesh relative to respective vertices of the first mean model mesh improves modeling motion of anatomical shapes.

摘要： A patient data record is described comprising a mean model representative of the patient and further comprises at least one shape model to represent data concerning the patient, in which the said mean model comprises at least one region and the said shape model comprises at least one sub-section, and in which the at least one sub-section of the shape model is linked to the equivalent region of the mean model. This has the advantage of allowing greater structure to the patient record. Further a system is described to present patient data upon queries generated by a user and arranged to access the claimed patient data record, and which is further arranged to provide access to information in the sub-section of the shape model when a query generated by the user accesses the equivalent region of the mean model. This system allows full use of the improved patient data record.
