Abstract: The invention relates to a method for generating a first signed data item, the first signed data item comprising first information to be stored in a distributed ledger database, wherein the distributed ledger database is managed by a computer network, the computer network comprising a plurality of nodes, wherein the method comprises at least the steps of (i) initiating, by a first computing device, the generating of a first data item by providing the second computing device with an initiating data item, wherein the first data item comprises the first information and the second computing is in data communication with the computer network via at least a first node of the computer network, (ii) digitally signing, by the first computing device, the first data item by using a first private key, thereby generating the first signed data item, and (iii) providing, by the first computing device, the second computing device with the first signed data item, the second computing device being configured to initiate the st

Abstract: Computer methods and devices for handling requests by using a distributed ledger database. An evaluation of a request is performed based on a first data item comprising first information about a state of a system and on a second data item comprising second information about a proposed action in response to the state of the system. The first and second data items are evaluated to establish whether, given the state of the system, the proposed action is appropriate, A third data item is provided and a fourth data item is accessed. The third data item comprises encrypted first information. The fourth data item comprises information for accessing encrypted information comprised in a first encrypted data item. The first data item is authenticated against the first encrypted data item to establish whether the information in the first data item is compatible with the information in the first encrypted data item.

Abstract: A system for determining and controlling the location of objects includes a transceiver fixedly arranged on or in the object, and a receiving antenna for receiving signals transmitted by the transceiver. A transmitting antenna transmits signals to the transceiver causing the transceiver to transmit signals. An antenna signal processing device evaluates signals received from the receiving antenna to determine a spatial position and location and a predefined identification of the transceiver relative to the receiving antenna, the object and a predefined reference point. A data processing device receives information from the antenna signal processing device about the position, location, and identification of the transceiver. In one aspect, the system is for determining the position and location of at least one transceiver relative to an object. In another aspect, the system is for determining and controlling the position and location of the object.

Abstract: The identifier and position and/or location of at least one identification mark is identified by a first optical recording device that is designed so that spatial position and/or location of an identification mark can be detected by the first optical recording device. A second optical recording device is designed so that it can scan a plan projection of at least a part of the measurement volume of the first optical recording device in a spatially resolved manner. Transformation information allows the definition of a region of interest (ROI) in the spatially resolved information about the scanned projection. The ROI is searched for the presence and type of identifier information to determine the identifier of the detected identification mark.

Abstract: The invention relates to high-frequency technology.

Abstract: The invention relates to a system for determining the position of radioactively marked target tissue of a patient in radiation therapy by means of a radiation therapy device. The system comprises at least one detector for the imaging detection of the radiation distribution of a radioactive radiation source that is located in target tissue region, a computing unit that is designed to calculate the pose of the target tissue region from measurement data of the detector and to calculate a correction variable as the difference between the calculated pose and comparison values, and an interface by means of which the data for the calculated pose of radioactively marked target tissue region and the correction variable can be transmitted by the computing unit to a radiation therapy device or a patient positioning device. The invention further relates to a corresponding method.

Abstract: A positioning system for a body comprises a flexible bag of a gas-impermeable material/including a valve to permit evacuation of the interior thereof, the bag containing a flowable granular material and at least one bolster. The body can be at least part of a human form, such as a patient. Systems are generally provided for specific body regions such as the hip or thorax, and for the whole body. The bolster is larger than the grains of the granular material. A size dimension of the bolster is therefore preferably at least 5 times the- size dimension of the granular material, although it sill usually be one or more orders of magnitude larger. Various forms of bolster are possible. A bolster that includes a generally flat section and an upstanding section extending therefrom can be used to locate a shoulder region of the patient in a reproducible yet comfortable form. A bolster that is generally cylindrical in shape can be used to support various areas of a patient such as the neck or knee.

Abstract: The invention relates to a radiotherapy system for directing a treatment beam onto an isocenter (14) in a patient (13), especially for tumor treatment in radiotherapy. Said radiotherapy system comprises a base (15) on which the patient (13) rests and a radiation device, more particularly, a linear accelerator (1) that generates a treatment beam (12). According to the invention, the direction of the treatment beam (12) can be regulated by means of a hexapod (3, 4, 5, 6, 7, 8, 9, 10).
