摘要:
In a method and system for data and signal transfer between different sub-units of a medically-related system, in particular a CT system, digitized signals and digital data are transmitted together on a transmission line by means of serial multiplexing. The digitized signals and the digital data are transferred combined into individual packets having a length that is so small that the adherence to a predetermined updating rate of the signals is achieved. The expenditure for the wiring as well as for future expansions in medically-related systems can be significantly reduced.

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.

A system is disclosed for producing CT image data records and for irradiating a patient. The 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 during the rotation of the rotary frame. The system includes a first operating mode for imaging in which during the revolution of the rotary frame 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.

In a method to control a medical apparatus of an installation having: a contact device for a patient, at least one electrical potential sensor that can be coupled to the body of said patient is integrated into the contact device. A signal evaluation device is provided with measurement signals generated with the electrical potential sensor for evaluation. The medical apparatus is connected with the signal evaluation device, and measurement signals that relate to the breathing and/or cardiac activity of the patient are acquired with the at least one electrical potential sensor coupled to the body of said patient upon contact of the patient with the contact device. Trigger signals are generated with the signal evaluation device based on the measurement signals that relate to the breathing cycle and/or the cardiac cycle of the patient. Operation of the medical apparatus is controlled based on the trigger signals.
摘要:
An image recording device is disclosed for the simultaneous recording of magnetic resonance image data and nuclear medical image data, in particular PET image data. In at least one embodiment, the image recording device includes a nuclear medical detector arrangement integrated into a magnetic resonance device, wherein a fluorescence detector arrangement including an optical system and designed for fluorescence imaging is also integrated into the magnetic resonance device.
摘要:
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.
