In a method and a device for data transmission between two components moving relative to each other, a first of the components has a number of transmission segments arranged along the movement direction and a second of the components has receiver units arranged along the movement direction. The data to be transmitted are divided among several transmitter segments for parallel transmission thereof. The data to be transmitted are configured in respective data packets, each having a packet identifier in addition to a data portion. A receiver device connected to the receiver units assembles the respective data portions of the respective received packets in a correct sequence using the respective packet IDs. The need for a position detector for noting the relative position of the transmitter segments and the receiver units is avoided.

Method and device for data transmission between two components moving relative to one another

A system includes exactly one rotary frame for holding at least one x-ray tube, and one radiation detector that is situated opposite, the x-ray tube being equipped with a diaphragm that can be dynamically adjusted. The system includes a first operating mode for imaging in which the x-ray tube radiate a ray fan of constant fan angle onto the oppositely situated detector, and CT image data records are calculated from the measured data of the detector. It includes a second operating mode for irradiation in which by using at least one imaging x-ray tube used in the first operating mode radiates an x-ray fan that varies with reference to alignment during the rotation of the rotary frame, is narrower perpendicular to the system axis, and remains aligned with the site of at least one tumor in the patient independently of the angular position of the rotary frame.

System for producing CT image data records and for irradiating a tumor patient

In a method and a device for positioning a patient in a medical diagnosis device or therapy device, an image-recording device records an image of the patient, which is displayed on a screen, and an image processor aids the positioning of the patient. At least one body region is automatically detected by the image processor, and a scan area is automatically suggested on the screen that covers the body region.

Method and arrangement for positioning a patient in a medical diagnosis or therapy device

In a method and a device for positioning a patient in a medical diagnosis device or therapy device having a position calculating device and a patient bed adjustable in at least one plane, at least one optical target marking is brought into conformity with a body region of the patient. At least one image recording device is used for obtaining an exterior image of the patient that is displayed on a screen. The target marking that is spatially coupled with the coordinate system of the diagnosis device or therapy device, is superimposed on the image of the patient on the screen such that a predetermined body region of the patient can be brought into a desired spatial correlation with the target marking by remote control movement of the patient bed.

In a CT scanning method and apparatus wherein a radiation source is displaced around a system axis and a ray bundle therefrom strikes a detector system that supplies scan data on the basis whereof two-dimensional scan images of the examination subject are determined in an image calculating device, parameters describing the position of a body part of an examining person situated in the beam path are determined by an analysis of registered scan images, and the radiation source is controlled dependent on the analysis result so that the radiation is reduced when the body part is located in the beam path.
