    摘要： An imager array includes a substrate with a plurality of superimposed layers of electrically conductive and active components. Sets of scan and data lines are electrically insulated from one another and also from a common electrode and active array components by dielectric material. Protection of the active components against static charge potential includes resistive means between the common electrode and a ground ring conductor around the array elements and in particular a thin film transistor circuit with a parallel pair of opposite polarity diode connected field effect transistors to safely drain the static charge during subsequent fabrication, test and standby period of the imager, while remaining in circuit during imager operation. Further electrostatic charge protection is provided to the array by an protective apparatus adapted to support the radiation imager while electrically contacting its ground ring to facilitate handling and processing while protecting against electrostatic charge damage during fabrication and testing, and enabling the positioning and bonding of the flexible external connections to the contact pads of the imager. Provision is made to enable heat and pressure for thermode bonding through the fixture to the contact pads while the imager is secured within the fixture.

    摘要： An improved design for a solid state X-ray detector that decreases the amount of moisture diffusion that occurs through seals used to attach a cover to a glass substrate panel, thereby protecting the scintillator from moisture damage. In one embodiment, a second hermetic or semi-hermetic seal is introduced between the scintillator and the outside environment to increase the path moisture must travel to reach the scintillator. In another embodiment, a metal frame, preferably a Kovar® frame, is hermetically or semi-hermetically sealed to the cover and glass substrate panel, thereby decreasing the amount of moisture diffusion through the semi-hermetic seal as compared to the prior art.

    摘要： A technique for establishing texture metrics and bone mineral density (BMD) within an anatomical region of interest. A digital imaging system is used to acquire a standard digital X-ray image with a wide field of view. The standard digital X-ray image is used to guide the imaging system to obtain an image of a region of interest. The standard digital X-ray image is used to calculate various texture metrics, such as a length of a fracture. A dual-energy digital X-ray image of the region of interest is acquired. The dual-energy digital X-ray image is corrected for scatter. The BMD of the region of interest may be established from the scatter-corrected dual-energy digital X-ray image. The BMD, the texture metrics, and/or the scatter-corrected dual-energy X-ray image may be displayed on the standard digital X-ray image.

    摘要： A system and method for improved imaging of a subject through the use of low dose exposure aided positioning is provided. The subject is positioned in an X-ray imaging system and imaged with a low dose pre-shot X-ray exposure to verify the positioning of the subject. If the subject's positioning is acceptable, the subject is then imaged with a full dose X-ray exposure. If the subject's positioning is not acceptable, the subject is repositioned and re-imaged with a low dose pre-shot X-ray exposure until the subject's positioning is acceptable. The low dose pre-shot X-ray exposure may take the form of a low dose X-ray imaging sequence where the radiation dose is less than the radiation dose of a full dose X-ray exposure.

    摘要： Described herein is a method of radiographic imaging providing low access time prior to the start of a user-requested X-ray exposure, while at the same time reducing or eliminating the imaging artifacts associated with short access times. The method includes the steps of exposing a radiographic detector for a time period t.sub.e ; reading the radiographic detector to obtain an exposure reading; reading the radiographic detector to obtain an offset reading, wherein the offset reading is obtained after a time period t.sub.w greater than t.sub.e ; and subtracting the offset reading from the exposure reading. Where the detector is subjected to readings lasting for periods t.sub.r prior to taking the exposure reading, detector readings lasting for t.sub.r are also taken during t.sub.w. After the final t.sub.r reading is taken during t.sub.w, the offset reading is then preferably taken after a period equal to t.sub.e. As a result, approximately the same detector sampling scheme is used both prior to and after the exposure reading (i.e., approximately the same operating conditions are imposed on the detector prior to the exposure reading and the offset reading), thereby providing more accurate offset readings and less image artifacts when the offset reading is subtracted from the exposure reading.

    摘要翻译： 本文描述了一种放射摄影成像方法，其在开始用户请求的X射线曝光之前提供低访问时间，同时减少或消除与短访问时间相关联的成像伪影。 该方法包括以下步骤：将射线检测器曝光一段时间; 读取放射线检测器以获得曝光读数; 读取放射线检测器以获得偏移读数，其中在大于te的时间段tw之后获得偏移读数; 并从曝光读数中减去偏移读数。 在采集曝光读数之前检测器经受持续时间段tr的读数的情况下，在tw期间也将采集持续到tr的检测器读数。 在tw期间进行最终tr读取之后，偏移读数优选在等于te的时间之后进行。 因此，在曝光读数之前和之后使用大致相同的检测器采样方案（即，在曝光读数和偏移读数之前，大致相同的操作条件施加在检测器上），从而提供更准确的偏移读数 并且当从曝光读数中减去偏移读数时，减少图像伪影。
