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 radiography system for obtaining a radiographic image of a subject, has a radiation source within an enclosure, the radiation source energizable to direct radiant energy along a radiation path toward an imaging receiver, wherein the radiation path is defined according to a collimator. A digital projector is coupled to the enclosure and is energizable to provide an illumination beam that outlines the defined radiation path.

摘要： A method for presenting radiographic images of a subject obtains, from the same radiographic image capture, at least a first image and a second image, wherein the at least first and second images differ in presentation. The method associates the at least first and second images as companion images according to one or more entered instructions. There is displayed at least a first executable data link that relates to a first storage location of the first image and a second executable data link that relates to a second storage location of the second image. In response to an operator selection of either of or both of the first and second executable data links, the method displays either the corresponding first or second image, or both companion images.

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.
