摘要： The invention relates to a method enabling the localization of objects, for example surgical instruments, in interventional radiology. The method utilizes the known geometrical shape of the object to be localized in order to simulate projections therefrom for comparison with real projection images. Optimum correspondence between simulation and real image yields the desired object position and object orientation. The invention is based on digital image processing and can be used in conjunction with customary radiological diagnostic apparatus such as C-arm fluoroscopy apparatus, computed tomography apparatus or magnetic resonance tomography apparatus. Objects to be localized can be provided with markers whose spatial position yields an unambiguous projection image.

摘要： Method and device for determining the position of a medical instrument, partially introduced into an object being examined, in a three-dimensional image data set of the object. In order to achieve a high accuracy of the position determination and minimize the expenditure required and thus save intricate registration steps prior to an intervention, simultaneously with the acquisition of an X-ray image, the spatial positions of the X-ray image and the spatial position of a medical instrument are acquired. Then, the spatial correlation between an X-ray image and a three-dimensional image data set is determined. This correlation is used to transform the spatial position of the medical instrument into a position relative to the three-dimensional image data set. This enables the formation of images containing image information acquired pre-operatively as well as intra-operatively, and also the reproduction of the instantaneous position of the medical instrument in the images.

摘要： The invention relates to a method and an arrangement for the intravascular or intracardial navigation of a catheter (5). Using an X-ray fluoroscopy device (1), firstly an image database of 2D images is generated, where at the same time as each 2D image (I) is taken the associated heartbeat phase is recorded using an ECG (8). During the catheter intervention, the position of the catheter (5) is measured by means of a position measurement unit (6), and at the same time the ECG and preferably also a signal that is dependent on the breathing movement are recorded. The current spatial position of the catheter (5) that is measured is then assigned the 2D image of the image database which corresponds in terms of the heartbeat phase and also possibly in terms of the breathing phase, on which image the position of the catheter can be represented.

摘要： The invention relates to an X-ray device, notable a device for X-ray fluoroscopy, which includes an X-ray source and an X-ray detector for the continuous formation of X-ray images of a patient (5) from an invariable position of the X-ray source (2) and the X-ray detector (3). The invention includes indicator means for illuminating and/or monitoring essentially the radiation zone over the patient which is traversed by X-rays. This offers the advantage that for the physician it quasi visualizes or monitors the radiation zone which is traversed by X-rays during a treatment with simultaneous formation of X-ray images so that the physician can make sure that he or she, notably his or her hands, is not inadvertently exposed to a continuous X-ray dose.

摘要： In the field of airport baggage inspection, a multi-level screening procedure is used. When a first level screening system (18) detects a “suspicious region” inside a bag, it is transferred to a next level system (2) where the bag gets rescanned. According to the present invention, a device/method is provided for finding and tracking the suspicious region inside the baggage which allows to reduce the area to be rescanned significantly. For this purpose, the image from the first level system together with the position of the suspicious region within the image is transferred from the first level system to the second level system. On arrival of the bag at the second level (21), a simple X-ray transmission image is measured using an additional source/detector system (6). The two images are then rigidly registered in order to exactly determine the suspicious region in the second level scanner system.

摘要： The invention relates to an X-ray examination apparatus for and a method of forming distortion-free X-ray images, which apparatus and method enable the imaging properties of the C-arm X-ray system to be derived from the patient image. To this end, a reference image (FIG. 4) is formed in a reference orientation of the X-ray examination apparatus and the reference imaging properties of the C-arm X-ray system are determined on the basis of the positions of calibration members (7, 8), which are mounted on the image intensifier (2) and/or the X-ray source (3) and are reproduced, and the known geometry and position relative to the image intensifier (2) and/or the X-ray source (3); the positions of the calibration members (7, 8) reproduced in a patient X-ray image (FIG. 5) are compared with the positions of the calibration members (7, 8) in the reference image (FIG. 4) and distortions occurring in the patient X-ray image are corrected on the basis of differences between the reproduced positions of the calibration members (7, 8) in the patient X-ray image (FIG. 5) and in the reference image (FIG. 4).

摘要： The invention relates to a system and an imaging method for visualizing areas (2) in a moving environment within the body of a patient (1), wherein the position of one or more markers, which are connected to an interventional device (4), is determined and used to determine the position of the areas (2) and/or of the interventional device (4) in images (6) which are recorded of the areas (2) and of their environment. According to the invention, the markers used are active locators which independently of the method used to record the images (6) generate data or signals for determining their position. Such an imaging method, which preferably uses electromagnetic locators, allows a considerably more robust representation of the visualized areas (2), with elimination of movements, than is possible using passive markers.
