摘要： A method is disclosed for the medical imaging of a body part, in particular the hand, wherein, in a tomographic image data record of the body part, points are marked which fix a face of interest running through the body part and which is singly or multiply curved. This curved face, which runs through all marked points, is then determined and the image content of the curved face is determined from the voxels of the image data record. This image content is mapped onto an observation plane which is finally displayed with the mapped image content on a screen. The method enables by way of example image representation of the structures of the left hand relevant to a skeleton examination by way of tomographic imaging.

摘要： In a method as well as a device for planning and/or monitoring an interventional high-frequency thermoablation, 3D image data of a region (1) of interest of a body are acquired with a tomographical imaging apparatus and are presented on an image display device. In the method, a database is provided in which, for at least one interventional instrument available for high-frequency thermoablation, a volume region for at least one high-frequency power generable with the instrument is established in which a thermoablation is achieved in a tissue with the instrument at this high-frequency power. Upon marking at least one ablation position in the image representations, a 3D object representing the volume region or a volume region derived from this is then mixed in at least semi-transparently at this ablation position. The method and the associated device enable a better planning and monitoring of an interventional high-frequency thermoablation by the user.

摘要： A computed tomography unit and a method are disclosed, for a computed tomography unit having at least one marking device for the positionally accurate marking of an intervention position by way of a laser beam on an object to be examined. The at least one marking device is assigned to a rotary frame of the computed tomography unit and is arranged directly in a recording plane of a recording system. As such, a positionally accurate marking of an intervention position with the aid of simple devices/methods is possible without a large numerical outlay, particularly even during operation of the computed tomography unit, that is say during a rotational movement of the rotary frame.

摘要： A method is disclosed for production of computer-tomographic scans via a CT system of a patient during an intervention with an instrument. An X-ray tube is moved on a rotation plane around the patient in order to produce a beam cone, and a detector with a plurality of detector elements measuring the radiation intensity after passing through the patient. Computer-tomographic scans are reconstructed from the measured values in a computation unit. The central direction of the beams of the scanning beam cone is set at an angle to the intervention axis, and at least one slice plane which differs from the rotation plane of the beam cone is displayed on a display.

摘要： In a method and system for controlling an examination process that includes medical imaging, which initially a first examination-relevant item of information is input and, based on this first information, first measures of the examination process are automatically established. A first segment of the examination process is subsequently automatically controlled according to at least one part of the first measures. During this first segment or subsequently, a second item of information is input and, based on this second information as well as on the first segment of the examination process, second measures are automatically established. A second segment of the examination process is automatically controlled according to at least one part of these second measures. In the system, an input unit allows input of the information, and a computer automatically establishes the measures, and a control unit controls the examination process.

摘要： An interactive user assistant for imaging processes analyzes medical image data pertaining to regions of interest. The user assistant compares displayed medical images and/or the data underlying the medical images with expected medical image data. The user assistant identifies whether or not the displayed medical image meets expectations or is plausible. The user assistant may use previously analyzed data in determining whether the displayed medical image is as expected. If the displayed medical image does not meet expectations, the user assistant determines whether or not the cause of the disagreement between the displayed and expected images is ascertainable. If the cause of the disparity between the images is ascertainable, the user assistant presents specific recommendations. If the cause of the disparity between the images is not ascertainable, the user assistant presents general suggestions.
