摘要： An apparatus and method for sensing a level of ionizing radiation directed from a radiation source through a subject and toward a digital radiography detector. Image data is obtained 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.

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 of processing a digital radiographic medical image. The digital radiographic medical image is accessed and a plurality of regions of interest is determined. For each of the plurality of regions of interest, steps are performed: determining at least one candidate region of interest (ROI) disease; identifying one ROI disease from the at least one candidate region of interest; determining a processing method appropriate to the identified one ROI disease; and applying the determined processing method to the region of interest to generate a disease enhanced region of interest. The digital radiographic medical image and one or more of the disease enhanced regions of interest can then be displayed.

摘要： A method for obtaining a radiographic image, the method executed at least in part on a computer, generates a first exposure and acquires image data from the first exposure as a first component image. A second exposure is generated using one or more parameters that are adjusted according to an image quality characteristic of the acquired image data from the first exposure. Image data is acquired from the second exposure as a second component image. One or more additional exposures are generated and an additional component image acquired with each additional exposure. A composite image is formed by combining image data content from the first and second component images and the one or more additional component images.
