摘要： A method for processing a radiographic image of a patient, executed at least in part on a host processor, initiates exposure in response to an instruction entered from an operator console and obtains radiographic image data from a digital detector that is subjected to the exposure. The obtained radiographic image data is analyzed according to a set of predefined criteria for diagnostic suitability of the image. One or more results of the diagnostic suitability analysis at the operator console is indicated and a listing of one or more corrective actions at the operator console according to the indicated results is provided.

摘要： An apparatus for cone beam computed tomography of an extremity has a digital radiation detector and a first device to move the detector along a circular detector path extending so that the detector moves both at least partially around a first extremity of the patient and between the first extremity and a second, adjacent extremity. The detector path has radius R1 sufficient to position the extremity approximately centered in the detector path. There is a radiation source with a second device to move the source along a concentric circular source path having a radius R2 greater than radius R1, radius R2 sufficiently long to allow adequate radiation exposure of the first extremity for an image capture by the detector. A first circumferential gap in the source path allows the second extremity to be positioned in the first circumferential gap during image capture.

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 obtaining a 3-D image. An initial volume image is obtained of a subject wherein the subject is stationary and in a first pose. One or more 2-D images of the subject are obtained as the subject is moving between the first pose and a second pose. An endpoint volume image of the subject with the subject stationary and in the second pose is obtained. At least the initial volume image is modified according to the one or more obtained 2-D images to form at least one intermediate volume image that is representative of the subject's position between the first and second pose. The at least one intermediate volume image can be displayed.
