Abstract: A radiography system having multiple digital radiographic detectors captures an image in each of the detectors when the x-ray source is fired. The detectors evaluate the captured images and a controller prioritizes the captured images according to the evaluations to determine which captured images are forwarded and in what order. At least one of the DR detectors captures a suitable diagnostic x-ray image.

Abstract: Radiographic imaging identifies a subject anatomy for radiographic image content and automatically identifies a subject's position from one or more sensor signals. The imaging apparatus issues re-positioning guidance signals for re-positioning the patient. Signals are generated to set an imaging exposure technique and component positions according to data associated with the subject anatomy. A radiographic image of the subject is acquired according to the component and technique signals by automatically energizing the x-ray source. The acquired radiographic image is analyzed using trained logic to determine clinical diagnostic suitability of the image and to identify one or more abnormalities in the subject anatomy.

An x-ray source is operable to be selectively positioned relative to each of the patient beds using a remote control system. The remote control system also controls firing of the x-ray source.

Abstract: A transducer transmits into the bone a first plurality of excitation pulses at a plurality of frequencies and measures a plurality of echoes corresponding to the plurality of excitation pulses. An ultrasound machine calculates a plurality of energies each corresponding to a respective one of the plurality of echoes and identifies a lowest echo corresponding to a lowest of the plurality of energies. The ultrasound machine matches the lowest echo to a corresponding one of the first plurality of excitation pulses, the corresponding one of the first plurality of excitation pulses having a chosen frequency. The ultrasound machine generates an acoustic impulse response by deconvolving the corresponding one of the first plurality of excitation pulses with the lowest echo, and generates an updated sensing matrix by convolving the initial sensing matrix with the acoustic impulse response. Subsequent ultrasounds use the updated sensing matrix.

Abstract: A drum for processing a thermal image medium has first and second end plates that extend orthogonally to an axis of rotation and enclose an inner core. First and second inner partitions along the axis define a first end zone between the first partition and the first end plate, a second end zone between the second partition and the second end plate, and a middle zone between the first and second partitions. Each inner partition has sleeve portions that extend outward from the partition, in an axial direction. A first lamp heater extends parallel to the axis and through one or more sleeve portions and has a first filament within the first end zone and a second filament within the second end zone. A second lamp heater extends parallel to the axis and through one or more sleeve portions and has a central filament within the middle zone.

At least one deciduous tooth among the one or more segmented teeth is identified. A virtual model of a target dentition arrangement of the patient dentition is generated, wherein the at least one deciduous tooth is replaced by a replacement permanent tooth.
