摘要： A method for sensing a level of ionizing radiation directed from a radiation source through a subject and toward a digital radiography detector, executed at least in part by a logic processor, obtains image data that relates the position of the subject to the digital radiography detector and assigns one or more radiant-energy sensing elements of the digital radiography detector as one or more exposure control sensing elements. The one or more exposure control sensing elements are sampled one or more times during exposure to measure the exposure directed to the subject. A signal is provided to terminate exposure according to exposure measurements obtained from the one or more exposure control sensing elements within the digital radiography detector.

摘要： A method for aligning a radiation source with a portable image receiver in a radiographic imaging system generates a magnetic field with a predetermined field pattern and with a time-varying vector direction at a predetermined frequency from an emitter apparatus that is coupled to the radiation source, wherein the generated magnetic field further comprises a synchronization signal. Sensed signals from the magnetic field are obtained from a sensing apparatus that is coupled to the image receiver, wherein the sensing apparatus comprises three or more sensor elements, wherein at least two of the sensor elements are arranged at different angles relative to each other and are disposed outside the imaging area of the image receiver. An output signal is indicative of an alignment adjustment according to the amplitude and phase of the obtained sensed signals relative to the synchronization signal.

摘要： Embodiments of methods and/or apparatus for a radiographic imaging system can include a radiographic detector including an image receptor to receive incident radiation and generate uncorrected electronic image data; a storage device to store calibration data at the detector, and a processor to generate calibration-corrected image data from the uncorrected electronic image data and the calibration data. The calibration-corrected image data can be further processed by the processor to perform image processing before transmitting a corrected image (e.g., DICOM image) to the radiographic imaging system. The detector can further include a display to display imaging system controls or the corrected image.

摘要： A radiography system for obtaining a radiographic image of a subject has a radiation source energizable to direct radiant energy along a radiation path and an imaging receiver sensitive to the radiant energy for forming the radiographic image. A sensor apparatus is disposed to provide one or more output signals that are indicative at least of centering of the radiation path with respect to the receiver, of an angle of the receiver relative to the radiation path, and of a source-to-image distance along the radiation path. A display apparatus generates, in response to the one or more output signals, a display that indicates the centering of the radiation path with respect to the receiver and that provides one or more values indicative of at least the source-to-image distance and the angle of the receiver relative to the radiation path.

摘要： An auto-positioning apparatus for an x-ray imaging system has a transport apparatus that is configured to position an x-ray source relative to a detector. A processor is configured to receive exam data that indicates an exam type and patient data that is indicative of patient height. The processor determines the present position of the first transport apparatus and determines an imaging position according to the exam data and patient data. The processor provides a positioning signal to the transport apparatus to move the x-ray source to the imaging position.
