Abstract: A radiographic imaging system having a number of useable digital radiographic detectors selectively activates one of the detectors to capture a radiographic image. The DR detectors each include a movement detector configured to transmit a movement signal when a movement of the corresponding detector is sensed. A portion of the system is disabled in response to receiving a movement signal transmitted from a motion sensor in a detector other than the active detector.

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.

Abstract: A method for visualizing patient dentition acquires a contour image of patient dentition and segments the contour image to identify one or more segmented teeth. 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.

The drum comprises a cylindrical surface (11) disposed around and parallel to an axis of rotation (A) of the drum, end plates (12) each extending orthogonally to the axis of rotation of the drum, and lamp heaters (14A-14B) extending parallel to the axis of rotation within the interior of the drum. By making use of thermal sensor measurements, the lamp heaters may be controlled to maintain a uniform dmm surface temperature.

Abstract: A flexible digital radiographic detector assembly includes a flexible sleeve enclosing a photosensor array supported by a flexible substrate. Integrated circuit readout electronics are coupled to the photosensor array and to a circuit board having conductive contacts. The contacts engage a hand carried read out electronics box to initiate a read out of image data captured in the photosensor array and to display the image data on a screen in the read out electronics box.

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 digital radiographic detector system includes a number of DR detectors enclosed by a housing. A base section with wheels has attached thereto a vertical column with a height adjustable horizontal arm extending therefrom. The housing with DR detectors therein is attached to a distal end of the horizontal arm. The housing comprises a major surface made from a radiolucent material to allow the detectors to capture radiographic images via x-rays transmitted through the major surface of the housing. The housing is configured to support the plurality of DR detectors therewithin.

Abstract: A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

Abstract: A digital radiographic image of a subject is captured using a reduced exposure level of an x-ray source. One or more exposure control regions in the image is mapped and associated with a predetermined exposure level. A difference between the predetermined exposure level setting and the reduced exposure level is used to set a diagnostic exposure level perhaps about twice as high as the reduced exposure level to capture a diagnostic image of the subject.

The detector is programmed to display the patient identifying information in human readable form and to access additional information about the patient stored in networked databases.

Abstract: An X-ray image quality control system includes an image acquisition unit configured to acquire an X-ray image and determine the type of imaged body part and the type of projection mode. A quality detection unit is configured to detect an image defect in X-ray image with regard to the type of the imaged body part and/or the type of the projection mode. The quality control system effectively identifies image defects including inaccurate positioning, patient movement, external object artifacts, and poor exposure. The system provides feedback to the technician at the image acquisition point to adjust the image acquisition solution in a timely manner.

An image slice from the reconstructed image volume displays in at least a first rendering having a first corresponding noise factor and a second rendering having a second corresponding noise factor, different from the first noise factor.
