Description

Method for pairing a mobile X-ray detector with an X-ray tube system Technical Field The present invention relates to medical X-ray systems, in particular to X-ray systems that can be used with mobile X-ray detectors, more particularly to a method for pairing a mobile X-ray detector with an X-ray system. Furthermore, the invention relates to a corresponding X-ray tube system. Background In digital workflow, portable X-ray detectors have replaced Computed Radiography (CR) boxes and are easy to handle. Clinically, multiple portable detectors of different sizes (sometimes different models) are often used and shared between X-ray rooms or systems. After pairing, the portable detector supports an intuitive workflow because it is easier to locate and lighter than any built-in detector. However, pairing of the portable detector with the X-ray system (i.e., the mobile detector and the X-ray machine identify each other) is quite cumbersome. For this purpose, the user must scan the bar code in the control room in order to register the detector with the system. As a result, the operator must decide which detector to use, and when pairing fails or in the event that the operator changes his mind, the operator must register the detector again in the control room, thus wasting a lot of time. Disclosure of Invention It is therefore an object of the present invention to provide an improved method for pairing a mobile X-ray detector with an X-ray tube system, in particular a method avoiding the pairing operation described above. Further, it is an object of the invention to provide a corresponding X-ray tube system. The object of the invention is solved by the subject matter of the independent claims, wherein further embodiments are contained in the dependent claims. In one aspect of the invention, a method for pairing a mobile X-ray detector with an X-ray tube system is provided. In this context, a mobile X-ray detector is an X-ray detector that is capable of movement, in particular between different rooms. The mobile X-ray detector may be a portable X-ray detector (i.e. a mobile X-ray detector that can be carried), but may also be a mobile X-ray detector that is attached to a mobile detector holder. An X-ray tube system is a medical system comprising an X-ray tube. The X-ray tube system may comprise a dedicated X-ray detector. In this case, the X-ray tube system may be referred to as an X-ray system. Alternatively, the X-ray tube system may not have a dedicated X-ray detector (i.e. the X-ray tube system is operated with only a mobile X-ray detector). In particular, the mobile X-ray detector and the X-ray tube system may form a digital X-ray system. In addition, the X-ray tube system may be configured to support a plurality of mobile X-ray detectors, more particularly the X-ray tube system may be configured to support a plurality of mobile X-ray detectors via detector sharing. Pairing of the mobile X-ray detector with the X-ray tube system may mean that the mobile X-ray tube system is utilized to identify the mobile X-ray detector. In particular, pairing of the mobile X-ray detector with the X-ray tube system may comprise arranging the X-ray tube system and/or the mobile X-ray detector such that an X-ray image may be obtained with the X-ray tube system using the mobile X-ray detector. More particularly, pairing the mobile X-ray detector with the X-ray tube system may include establishing communication between the X-ray tube system and the mobile X-ray detector, configuring the X-ray tube system with the mobile X-ray detector to acquire one or more X-ray images, and/or configuring the mobile X-ray detector with the X-ray tube system to acquire one or more X-ray images. The mobile X-ray detector includes a first wireless communication interface. The first wireless communication interface may be used for pairing the mobile X-ray detector with the X-ray tube system, for communication between the mobile X-ray detector and the X-ray tube system, and/or for transmitting an X-ray image obtained by the mobile X-ray detector. The X-ray tube system comprises an X-ray tube. The X-ray tube is configured to emit X-rays, which an X-ray detector (in particular a mobile X-ray detector) is capable of detecting to obtain an X-ray image (in particular a medical X-ray image). In addition, the X-ray tube system comprises at least one sensor, a computing unit and a second wireless communication interface. The second wireless communication interface may be used for pairing the X-ray tube system with the mobile X-ray detector and for communication between the X-ray tube system and the mobile X-ray detector. According to the method, sensor data is obtained by at least one sensor. The sensor data is then transmitted by at least one sensor to a computing unit. Thus, sensor data is received by the computing unit from the at least one sensor. The transmission and reception of sensor data may be performed using a wired connection and/or a wireless connect
