摘要： This invention relates to a method and image processing apparatus for automatically correcting mis-orientation of medical images. One or more image processing software modules are used to extract (101) anatomical areas from the medical images. It is determined (103) whether the extracted anatomical areas correspond to reference anatomical areas, but the reference anatomical areas have associated thereto data indicating the orientation of the reference anatomical areas. If the extracted anatomical areas correspond with the reference anatomical areas, the true orientation of the extracted anatomical areas is determined (105) by realigning the medical image until the orientation of the extracted anatomical areas corresponds to the orientation of the reference anatomical areas.

摘要： The invention relates to a method and a device for determining the distribution of an X-ray fluorescence (XRF) marker (16) in a body volume (14). The body volume (14) is irradiated with a beam of rays (12) from an X-ray source (10) with a first ray component with a quantum energy just above and a second ray component with a quantum energy just below the K-edge of the XRF marker (16). Secondary radiation emitted from the body volume (14) is detected in a location-resolved way by a detector (30). To separate the X-ray fluorescence components in the secondary radiation from background radiation, the body volume is irradiated for a second time with a beam of rays from which the first ray component has been substantially removed by a filter (22) made from the material of the XRF marker.

摘要： The invention relates to a device for generating X-rays (18) comprising an electron source (3) for emitting electrons accommodated in a vacuum space (2), a liquid metal circuit including a liquid metal for emitting X-rays as a result of the incidence of electrons and a pumping means (11) for causing a flow of the liquid metal through a constriction (7) where the electrons emitted by the electron source (3) impinge upon the liquid metal, and a radiation window (12) bounding said constriction (7), which is transparent to electrons and X-rays and separates the constriction (7) from the vacuum space (2). To provide a device for generating X-rays in which a cross-sectional area of the constriction substantially corresponds to an intended, desired cross-sectional area due to a self-regulating process without the need for external or additional components or electronics, it is proposed that said constriction (7) being bounded by a compensation window (13) opposite of said radiation window (12), which separates the constriction (7) from a pressure chamber (14) containing liquid metal provided by said liquid metal circuit via a connection (15), and which, during operation, has a profile (p′) as a result of a deformation caused by a pressure in the pressure chamber (14) different from the pressure in the constriction (7) which substantially matches a profile (p) which the radiation window (12) has, during operation, as a result of a deformation of the radiation window (12) caused by a pressure of the liquid metal in the constriction (7).

摘要： A system (100) for segmenting an object in an image adapts a first model for segmenting the object to the image. A feature is extracted from the image based on the adapted first model. A second model is selected for segmenting the object from a plurality of models for segmenting the object, based on the feature extracted from the image. The second model includes additional detail of the object. The second model is utilized based on the adapted first model and/or the feature extracted from the image; the initialized second model is adapted to the image. The features extracted from the image based on the adapted first model help the system (100) to select the second model for segmenting the object from a plurality of models for segmenting the object. The adapted first model and/or the extracted features are also used for initializing the second model. Because the second model includes the additional detail of the object, the segmentation result using the second model is more complete than the segmentation result Obtained using the first model. Moreover, the initialization of the second model based on the adapted first model and/or the detected features Improves the accuracy of the second model adaptation.

摘要： The invention relates to a system (100) for segmenting an object in an image, comprising a first adapter (110) for adapting a first model for segmenting the object to the image, an analyzer (115) for extracting a feature from the image based on the adapted first model, a selector (120) for selecting a second model for segmenting the object from a plurality of models for segmenting the object, based on the feature extracted from the image, wherein the second model comprises additional detail of the object, an initializer (125) for initializing the second model based on the adapted first model and/or the feature extracted from the image, and a second adapter (130) for adapting the initialized second model to the image. The features extracted from the image based on the adapted first model help the system (100) to select the second model for segmenting the object from a plurality of models for segmenting the object. The adapted first model and/or the extracted features are also used for initializing the second model. Because the second model comprises the additional detail of the object, the segmentation result using the second model is more complete than the segmentation result obtained using the first model. Moreover, the initialization of the second model based on the adapted first model and/or the detected features improves the accuracy of the second model adaptation.
