摘要： The present invention relates to an X-ray detector comprising a directly converting semiconductor layer (60) having a plurality of pixels for converting incident radiation into electrical measurement signals with a band gap energy characteristic of the semiconductor layer, wherein said incident radiation is x-ray radiation emitted by an x-ray source (2) or light emitted by at least one light source (30, 33). Further, an evaluation unit (67) is provided for calculating evaluation signals per pixel or group of pixels from first electrical measurement signals generated per pixel or group of pixels when light from said at least one light source at a first intensity is coupled into the semiconductor layer and second electrical measurement signals generated per pixel or group of pixels when light from said at least one light source at a second intensity is coupled into the semiconductor layer, wherein said evaluation unit is configured to detect per pixel or group of pixels a noise peak in said first and second electrical measurement signals and to determine offset and gain per pixel or group of pixels from the detected noise peaks. A detection unit (69) is provided for determining detection signals from electrical measurement signals generated when x-ray radiation is incident onto the semiconductor layer, and a calibration unit (68) is provided for calibrating the detection unit on the basis of the evaluation signals.

摘要： Provided is an X-ray generator which includes:an electron path 8; a target 9c disposed on a substrate 9a, in which electrons having passed through the electron path 8 are made to emit at the target 9c and to generate an X-ray, wherein: the target 9c is disposed at the central area of the substrate 9a; at least a part of a peripheral area of the substrate 9a which is not covered with the target 9c has higher transmittance than that of the central area of the substrate 9a covered with the target 9c, with respect to the X-ray generated when electrons having reflected from the target enter an inner wall of the electron path. X-ray generation efficiency may be improved by effectively using electrons reflected off the target 9c.

摘要： Methods and an x-ray system for dynamically regulating x-ray dose. An x-ray beam is generated and collimated at a source collimator and detected after the x-ray beam traverses an inspected object. A filter may be dynamically interposed by translation of the filter between a focal spot of the source and the source collimator in such a manner as to maintain the portion of the x-ray beam that traverses the inspected object below a specified limit. Alternatively, an aperture of the source collimator may be varied in size or position relative to the focal spot.

摘要： A high energy radiation generator utilizes sliding friction in a low pressure environment to generate high energy radiation, for example x-rays. The sliding friction may be generated by sweeping one material against a second material, for example rotating a surface of a rotor against a membrane, in the presence of an electron target, which may be one of the first material or the second material, or a different material.

摘要： Radiation generating apparatus includes an envelope and a radiation tube disposed inside the envelop. A cooler is connected to the envelope at an inlet port and an outlet port. Coolant circulates between the cooler and the envelope through the inlet port and outlet port. A partition plate divides the inside of the envelope into a first chamber on the side of the radiation tube and a second chamber on the side of the inlet port. An air bubble chamber provided at an upper portion of the second chamber collects air bubbles formed in the coolant. A protrusion projecting toward the second chamber is provided at an end of the partition plate on the side of the opening. Since the air bubbles are moved due to buoyancy force or inertial force when the apparatus is rotated, it is possible to prevent radiation from passing through the air bubbles.
