    摘要： A system for controlling operation of an imaging or therapy apparatus. The system comprises an interface (IN) for receiving a pain measurement signal as measured by one or more sensors (S) in relation to an anatomic part (BR) of the patient (PAT) i) being imaged in an imaging procedure by the imaging apparatus or ii) being under therapy in a therapy procedure delivered by the therapy device, whilst the part (BR) is held in an adjustable fixation device (FD). A control unit (CU) of the system is configured to process the pain measurement signal to compute at least one control signal. A control interface (CIF) of the system is configured to interact during the imaging or therapy procedure with the imaging apparatus (IA) and/or the fixation device (FD) based on the control signal to a) influence the imaging or therapy procedure and/or b) to adjust the fixation device so as to change the manner in which the part (BR) is being held.

    摘要： An X-ray source (10) for emitting an X-ray beam (101) is proposed. The X- ray source (10) comprises an anode (12) and an emitter arrangement (14) comprising a cathode (16) for emitting an electron beam (15) towards the anode (12) and an electron optics (18) for focusing the electron beam (15) at a focal spot (20) on the anode (12). The X-ray source (10) further comprises a controller (22) configured to determine a switching action of the emitter arrangement (14) and to actuate the emitter arrangement (14) to perform the switching action, the switching action being associated with a change of at least one of a position of the focal spot (20) on the anode (12), a size of the focal spot (20), and a shape of the focal spot (20). The controller (22) is further configured to predict before the switching action is performed, based on the determined switching action, the size and the shape of the focal spot (20) expected after the switching action. Further, the controller (22) is configured to actuate the electron optics (18) to compensate for a change of the size and the shape of the focal spot (20) induced by the switching action

    摘要： The present invention relates to a detector (10) for a dark-field and/or phase-contrast interferometric imaging system. The detector comprises a plurality of pixels (50), a plurality of first detector arrays (20), pixel a plurality of second detector arrays (30), and a processing unit (40). The plurality of pixels are arranged in a two-dimensional pattern. Each pixel comprises a first detector array and a second detector array. Each first detector array comprises a plurality of fingers (22). Each second detector array comprises a plurality of fingers (32). For each pixel the fingers of the first detector array are interleaved alternately with the fingers of the second detector array. For each pixel interaction with an incident X-ray photon can lead to charge generation in at least one finger of the first detector array of that pixel and can lead to charge generation in at least one finger of the second detector array of that pixel. For each pixel the first detector array is configured to detect a cumulative charge associated with the plurality of fingers of the first detector array and the second detector array is configured to detect a cumulative charge associated with the plurality of fingers of the second detector array. For each pixel the processing unit is configured to assign an X-ray interaction event to either the first detector array or the second detector array on the basis of the detector array that has the highest cumulative charge.
