    Abstract: A system, method, and computer-readable media are provided for facilitating clinical decision making, and in particular, decision making based on a third party's clinical situation by determining and providing useful, up-to-date information, such as patient-related information to a decision maker. In one embodiment, a user first identifies an information item concerning a patient. Based on that item, a set of related information items is determined and prioritized, and a reference pointer, which identifies the set of related information, is generated. The reference pointer is communicated to the user's mobile device. Subsequently, the user's mobile device requests information from the set of information items associated with the reference pointer, and provides information authorization information. Following authentication of the user's credentials, updates of information from the set of information items is communicated to the user's mobile device as they become available.

  • Patent number: 10310106
    Abstract: A dual/multi-energy x-ray image sensor with stacked two-dimensional pixel arrays. Each pixel in one pixel array has a corresponding “overlaid” pixel in the other pixel array. The pixel arrays are stacked parallel and aligned so that they are nominally normal to the x-ray path, and so that a straight path taken by an x-ray photon from the x-ray source to a pixel in one pixel array will also nominally intersect the corresponding pixel in the other pixel array(s). The energy image sensor provides an x-ray scanning detector system, which has increased signal levels and signal-to-noise ratios over dual- or multi-energy detectors using linear diode arrays, specifically when the pixel arrays are TDI pixel arrays that offer higher sensitivities in high-speed line-scan applications. Signal processing circuitry is placed on a periphery of the pixel arrays and shielded. Dual-to-multiple energy applications can be accomplished by increasing the number of stacked pixel arrays.

  • Patent number: 10279198
    Abstract: A scintillation material is longitudinally packaged in a circumferentially surrounding sheath, where the sheath has a lower index of refraction than the scintillation material, to form a scintillation optic or scintillation fiber optic. The scintillation material yields secondary photons upon passage of a charged particle beam, such as a positively charged residual particle beam having transmitted through a sample. The internally generated secondary photons within the sheath are guided to a detector element by the difference in index of refraction. Multiple scintillation optics are assembled to form a two-dimensional scintillation array coupled to a two-dimensional detector array, such as for use in determination of state of the residual charged particle beam, determination of an exit point of the particle beam from the sample, path of the treatment beam, and/or tomographic imaging.

  • Patent number: 7498598
    Abstract: A system for reading out X-ray information stored in a phosphor layer, includes: a read-out unit having components for irradiating the phosphor layer with stimulation radiation which can stimulate the phosphor layer to emit emission radiation dependent upon the X-ray information contained in the phosphor layer, and for collecting the emission radiation stimulated in the phosphor layer; and a carrier onto which the read-out unit is mounted. At least one of the components of the read-out unit is mounted onto the carrier over at least one first bearing which has a translatory degree of freedom in a first direction. The first bearing enables movement of the at least one component in relation to the carrier in the first direction.

  • Patent number: 7449709
    Abstract: A cassette is delivered from a cassette loader through a stock unit to a releasing unit. After a stimulable phosphor panel is supplied from the cassette to a reading unit by an unlocking mechanism and a panel ejecting mechanism, the cassette is fed to a position below an erasing unit so as to wait for the stimulable phosphor panel. After recorded radiation image information is read from the stimulable phosphor panel by the reading unit, the stimulable phosphor panel is fed to the erasing unit, which erases remaining radiation image information from the stimulable phosphor panel. Thereafter, the stimulable phosphor panel is stored back into the waiting cassette, which is delivered to a cassette discharger.

  • Patent number: 7355196
    Abstract: A stimulable phosphor sheet, on which a radiation image of an object has been stored, is scanned with stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored on the stimulable phosphor sheet during exposure of the stimulable phosphor sheet to radiation. The light, which is emitted by the stimulable phosphor sheet when the stimulable phosphor sheet is scanned with the stimulating rays, is detected, and an image signal representing the radiation image of the object is acquired. The scanning of the stimulable phosphor sheet with the stimulating rays is performed from an object image-carrying edge area, in which a radiation image pattern representing the object has been stored, the object image-carrying edge area being one of edge areas of the stimulable phosphor sheet.
