The computed tomography device has a gantry with an opening and a radiation protection apparatus for covering the opening. The radiation protection apparatus includes a radiation protection cover and a pivoting apparatus, wherein an object under examination may be inserted into the opening along a system axis of the gantry when the radiation protection cover is in a first position relative to the gantry. The radiation protection cover is pivotably mounted relative to the gantry about a pivot axis by the pivoting apparatus such that a first pivoting motion of the radiation protection cover about the pivot axis enables the radiation protection cover to be lowered relative to the gantry from the first position to a second position. The computed tomography device may furthermore include at least one of a lighting system or a camera system.

The disclosure relates to a wheel suspension of a device having an electrical drive of a wheel for supporting a manual movement impulse. The wheel suspension includes a connector piece movably or bendably arranged between a support element or support frame connected to the device and between an interior stator of an electrical drive, wherein the connector piece is held in a starting position due to the gravity of the device, without other influencing forces. The wheel suspension also includes at least one sensor that detects a deflection of the connector piece, and a control device designed such that the control device together with the electrical drive counteracts a deflection or bending of the connector piece.

Collision-free movement of a mobile medical device, such as a mobile medical imaging device, in a room is controlled via a man-machine interface. A model of the room environment is created and displayed, together an actual position of the medical device. The room model and the actual position are based at least in part on real-time sensor data. A destination position for the medical device is entered, the entered destination position is displayed and a collision-free movement path is generated from the actual position to the destination position. The movement path is displayed in the room model. A movement command relating to the displayed movement path is entered and the medical device is driven along the entered movement path from the actual position to the destination position.

An x-ray apparatus is configured with a C-arm frame. At one end of the C-arm frame an x-ray source is arranged and at the other end of which a detector for recording radiation emitted by the x-ray source is arranged. A voltage generator is provided for supplying a voltage to the x-ray source. At least one component of the voltage generator and the x-ray source are arranged separately from one another. The at least one component of the voltage generator is positioned at the same end of the C-arm frame at which the detector is arranged, as a result of which a weight equalization can be implemented in a simpler manner.

In a method for image guided prostate cancer needle biopsy, a first registration is performed to match a first image of a prostate to a second image of the prostate. Third images of the prostate are acquired and compounded into a three-dimensional (3D) image. The prostate in the compounded 3D image is segmented to show its border. A second registration and then a third registration different from the second registration is performed on distance maps generated from the prostate borders of the first image and the compounded 3D image, wherein the first and second registrations are based on a biomechanical property of the prostate. A region of interest in the first image is mapped to the compounded 3D image or a fourth image of the prostate acquired with the second modality.

In a method and apparatus for detecting tumorous cell tissue in a gastrointestinal tract, electromagnetic radiation is emitted in a locally defined manner from an endoscope onto cell tissue and, after deactivation of the radiation, the decay of the inherent fluorescence intensity of the irradiated cell tissue, excited by the electromagnetic radiation, is detected, with temporal and spectral resolution and with a known scanning rate for at least one wavelength. From the intensity measurement values obtained in this manner, the difference autocorrelation function of the intensity decay is determined, from which a fractal dimension for the irradiated cell tissue is determined. The value of the fractal dimension is used to classify the irradiated cell tissue as to a degree to which the cell tissue is tumorous.

In a system and method for x-ray brachytherapy, a probe is introduced into the body of a subject, the probe carrying an x-ray source that radiates x-rays into an exposure area outside of the probe within the body of the subject. A number of markers are located in or on the probe, that are detectable in an image generated by an imaging device. The markers are located in or on the probe in a known spatial relation to the exposure area, so that the position of the exposure area can be determined by identifying the markers in the displayed image.

The invention relates to a method and to an apparatus for recognizing tumorous living cell tissue. It furthermore relates to a method and to an apparatus for recognizing tumorous cell tissue at collected living cell tissue samples. In the method, electromagnetic radiation is emitted with local definition onto cell tissue by a radiation source and, after deactivation of the radiation source, the decay behavior of the inherent fluorescence intensity of the cell tissue excited by the electromagnetic radiation is detected at the cell tissue in a time resolved and spectrally resolved manner at known sampling rate(s) for at least one wavelength using a detector. The difference autocorrelation function C(t) of the intensity decay behavior is determined using the determined measured intensity values, the fractal dimension Dfor the respective irradiated cell tissue is calculated from this and the value of the fractal dimension Dis used for a classification with respect to a presence of a tumor in the respective irradiated cell tissue.
