摘要： The invention relates to a registration method (100) of registering a second image dataset with a first image dataset on the basis of a set of landmarks, said registration method (100) comprising a weight-assigning step (125) for assigning a weight to each coordinate of each landmark from the set of landmarks and a registering step (145) for registering the second image dataset with the first image dataset on the basis of the weight assigned to the each coordinate. Choosing an appropriate set of landmarks and assigning an appropriate weight to each coordinate of each landmark from the set of landmarks can be used for optimizing selected displacements of a designated anatomical structure comprising elastic bodies and/or a plurality of independent rigid bodies in a sequence of image datasets. This enables rendering a sequence of views wherein the designated anatomical structure is not displaced off a viewing plane and/or a selected part of the designated anatomical structure is not displaced in a viewing plane.

摘要： A method for creating a model of a part of the anatomy from the scan data of several subjects is described. The method comprises the steps of collecting scan data; applying a feature detector to the scan data; converted the output of the feature detector into a common reference system; and accumulating the converted data to generate the model. It is therefore possible for the method to generate a model from the scan data of several subjects automatically. The method may also include an optional step of receiving user input to select which of the accumulated data should be included in the final model. This user input requires much less effort than manual contouring and is substantially independent of the number of subjects used to create the model.

摘要： The invention relates to automatically adjusting an acquisition protocol for dynamic medical imaging, such as dynamic CT, MRI or PET imaging. The protocols are adjusted based on anatomic and dynamic models (10, 12, 14) which are individualized or fitted to each patient based on a scout scan (6, 8). The adjustment can compensate for changes in the patient due to patient motion (e.g. breathing or heartbeat) or flow of contrast or tracing agent during the sequence. This ensures that changes in the reconstructed images are indicative of pathological changes in the patient and not caused by patient motion or changes in scanning parameters or timing. The dynamic model can be a motion model (12) used to predict the motion of anatomic/physiologic features, typically organs, during scanning, or a haemodynamic model (14) used to predict flow of the contrast agent allowing for precise timing of the scanning sequence.
摘要翻译：本发明涉及自动调整用于动态医学成像的采集协议，例如动态CT，MRI或PET成像。基于解剖和动态模型（10,12,14）调整协议，这些解剖和动态模型基于侦察扫描（6,8）对每个患者进行个性化或拟合。该调整可以补偿由于患者运动（例如呼吸或心跳）或对比剂或跟踪剂在序列期间的流动引起的患者的变化。这确保重建图像中的改变指示患者的病理变化，而不是由患者运动或扫描参数或时间的变化引起的。动态模型可以是用于预测解剖/生理特征（通常是器官）在扫描期间的运动的运动模型（12）或用于预测造影剂的流动的血液动力学模型（14），其允许扫描的精确定时序列。

摘要： A method, an apparatus and a computer program for transferring scan geometry between a first region and a second region, similar to the first region includes identifying the first and second regions in an overview image, followed by determining of the first scan geometry corresponding to the first region. Then, the first scan geometry is transferred into the second scan geometry corresponding to the second region using information on geometrical correspondence between the first and second regions. The transferring includes establishing corresponding mappings between similar regions and their respective scan geometries.

摘要： 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.
