    摘要: A diagnostic imaging system and process permits construction of an image of an area of an interfacial surface within the body of a subject, such as the heart-lung interface. The imaging system includes radiation source means for generating a shaped beam of penetrating radiation for illuminating the interfacial surface. Radiation scattered from tissue at the interface is detected by a plurality of directional radiation detectors which can be automatically positioned and oriented so that their fields of view intersect the beam of radiation and the interfacial surface.

    摘要: A shadow aperture backscatter radiography (SABR) system includes at least one penetrating radiation source for providing a penetrating radiation field, and at least one partially transmissive radiation detector, wherein the partially transmissive radiation detector is interposed between an object region to be interrogated and the radiation source. The partially transmissive radiation detector transmits a portion of the illumination radiation field. A shadow aperture having a plurality of radiation attenuating regions having apertures therebetween is disposed between the radiation source and the detector. The apertures provide illumination regions for the illumination radiation field to reach the object region, wherein backscattered radiation from the object is detected and generates an image by the detector in regions of the detector that are shadowed by the radiation attenuation regions.

    摘要: A reconfigurable collimated radiation detector, system and related method includes at least one collimated radiation detector. The detector has an adjustable collimator assembly including at least one feature, such as a fin, optically coupled thereto. Adjustments to the adjustable collimator selects particular directions of travel of scattered radiation emitted from an irradiated object which reach the detector. The collimated detector is preferably a collimated detector array, where the collimators are independently adjustable. The independent motion capability provides the capability to focus the image by selection of the desired scatter field components. When an array of reconfigurable collimated detectors is provided, separate image data can be obtained from each of the detectors and the respective images cross-correlated and combined to form an enhanced image.

    摘要: A snapshot backscatter radiography (SBR) system and related method includes at least one penetrating radiation source, and at least one substantially transmissive radiation detector. The substantially transmissive radiation detector is interposed between an object region to be interrogated and the radiation source. The substantially transmissive radiation detector receives and detects forward radiation from the radiation source before transmitting a portion thereof to interrogate the object region, wherein a portion of backscattered radiation provided by the object region is detected by the detector. A changeable collimating grid having a plurality of spaced apart radiation absorbing features is coupled to structure changing a position of the plurality of features and is disposed in at least one of the path of the forward radiation and the path of the backscattered radiation. An image of the object can be obtained by subtracting the forward radiation detected at the detector, or an estimate thereof, from a total of all radiation detected by the detector. Integrated circuit inspection, land mine detection, and luggage or cargo screening systems can all be SBR based.
