摘要： A therapeutic system includes a therapy module to direct a therapeutic action, e.g. focused ultrasound or RF energy to a target. An imaging module, such as a magnetic resonance examination system, generates image information of a therapy region that includes the target. By way of a motion analysis module, a motion vector field is derived from the image information of the therapy region. A control module controls the therapy module based on the motion vector field. For example, based on t the motion vector field, an accurate temperature distribution is derived from magnetic resonance signals and the motion vector field. Also magnetic resonance elastography data may be employed to improve the accuracy of the temperature distribution.

摘要： A method for localising a target 2 (fi. a tumour) in an object 4 (fi. human tissue) by means of scanning the object with a fan shaped X-ray beam 6. In known methods the X-ray beam is scanned twice over the object. In the first scan a shadow image of the object 4 and the target 2 in it is projected on an X-ray detector 10. In the second scan the position and the orientation of the X-ray beam 6 differs from the position and orientation of it in the first scan. Also during the second scan a shadow image of the object and the target is projected on the X-ray detector, in such a way that the positions of the target on the detector are mutually different. In this way the height of the target above the detector surface 10 may be calculated from the distance between the two shadow images of the target if both positions of the X-ray beam as well as both orientations are known. According to the invention it is proposed to translate and simultaneously rotate the X-ray beam 6 during the scan, the translatory and rotational movements being connected in such a way that the shadow image 12 of the target 2 is kept on the surface 10 of the detector during the scan. In this way it is possible to measure the translation d of that image during the scan, from which translation in combination with the translation D and the rotation during the scan the height of the target 2 above the detector surface 10 may be calculated. In this way only one scan is needed.

摘要： It is an object of the invention to provide a linking system (100) for linking a particular object model from a set of object models with an object in an image that requires relatively few user interactions to create the link. This is achieved in that the linking system comprises a first selection unit (110) for selecting the object in the image, a determining unit (120) for determining a subset of related candidate object models from the set of object models on the basis of the selected object, and a second selection unit for selecting the particular object model from the subset of related candidate object models. By starting the linking process with selecting the object in the image, the task of determining the subset of related candidate object models is delegated to the determining unit and does not require user interaction. This means that a kind of filtering is applied to find an appropriate model. The user does not have to make the selection of the model from the relatively large set.
