5 results about "Computed tomography scanner" patented technology

The computed tomography (CT) scanner gantry rotates relative to the fixed substrate of the CT scanner. During gantry rotation, digital data is transmitted from a data source via a modulator, transmission channel, and demodulator to a data receiver between the gantry and the substrate. A predistortion device located upstream of the transmission channel predistorts the transmitted signal generated by the modulator from the data source through modulation according to a predistortion rule. Only the predistorted transmitted signal is transmitted to the transmission channel. Alternatively or additionally, a postdistortion device located downstream of the transmission channel postdistorts the signal transmitted via the transmission channel according to a postdistortion rule, and only the postdistorted signal is transmitted to the demodulator. The predistortion rule and / or postdistortion rule are repeatedly reset by a setting device during gantry rotation.

The invention relates to a radiological gripping device (1) for a radiological device (50), such as an X-ray device (51), a magnetic resonance tomograph (52), a computed tomograph (53) or a radiation therapy device (54), comprising a stationary device (2) and at least one carrying arm (3) with at least one shaft element (4) and a carrier element (5) pivotably seated on the stationary device. Furthermore, a locking device (6) for locking the carrying arm (3) in at least one locking position (7) is provided. An actuating mechanism (8) is provided for actuating the locking device. A gripping device (9) is also included, which is arranged for fastening to the carrying arm (3) to provide the possibility of gripping for a patient. The shaft element (4) of the carrying arm (3) is pivotably seated on the stationary device (2). The actuating mechanism (8) comprises at least one force direction unit (200), which locks the force transmission in one direction in order to use the operating force transmitted into the flexible pull element (19) for actuating the locking device (6) or to actuate with this force.

This application claims a rack assembly and a computed tomography scanner. The rack assembly includes a rotating rack and an imaging assembly mounted on the rotating rack. The imaging assembly includes a correspondingly disposed X-ray source and a detector. The detector is provided with a position adjustment mechanism for adjusting its axial position relative to the rotating rack. When the detector deviates from its position, the position adjustment mechanism is used to adjust the detector's axial position relative to the rotating rack. This allows the detector to be adjusted relative to the X-ray source in the axial direction of the rotating rack, ensuring focal alignment between the X-ray source and the detector in the imaging assembly. This reduces the requirements for the overall dimensional control precision of the rotating rack, thereby reducing costs.
