    摘要: A method is provided for maximizing substrate usage in the fabrication of flat panel displays or detectors, while also maximizing electrostatic protection for the displays or detectors. Initially, at least two detectors are positioned on the substrate, with each of the detectors having a guard ring of a certain width. At least a section of the guard ring width of one detector is approximately adjacent to a section of the guard ring width of another detector. The approximately adjacent guard ring width sections are then positioned such that a maximum overlap of the adjacent guard ring width sections is achieved, while still providing each display or detector with electrostatic discharge protection. Each of the detectors is separated from the other detectors and the remainder of the substrate by the process of scribing partially through the substrate and breaking at the scribe mark or by sawing.

    摘要: Systems and methods are provided for managing power consumption of a medical imaging detector by the use of triggering signals, environmental condition data, and/or determination of a variable time interval triggering event that is unique for each power consumption state. Systems and methods are provided for managing power and temperature of a device, after receiving a request for a function to be performed by the device determining an “on” trigger component, an “off” trigger component, associated circuits for performing the received function, providing power to the associated circuits upon the occurrence of the “on” trigger component, and removing power to the associated circuits upon the occurrence of the “off” trigger component. Further, an instruction is described for determining and displaying a variable time interval that is indicative of a time to change from one state to a desired state.

    摘要: A technique is provided for automatically initiating reset of a digital detector. Generally, a digital detector has an array of rows and columns of pixels, read out electronics and scan electronics, that are configured to generate and transmit signals based upon radiation impacting the detector. The technique incorporates an automatic reset circuit that provides state machines to implement a reset if no readout or scrub command is received within a set time interval, or if communication with a readout control circuit is not available. The technique also includes methods for monitoring inputs, and resetting the charge on the rows and columns of pixels.

    摘要: A large area solid state x-ray detector employs a number of photodiodes that are charged electrically then discharged by exposure to x-ray. Ghost images resulting from release of charge trapped in photodiodes during prior exposures are eliminated by adjusting the biasing during a reset portion of the imaging cycle. Biasing may be increased to decrease the recharge time or reversed in polarity to evenly discharge the diodes or decreased to preserve the offset so that it may be removed from subsequent images by image processing.

    摘要: A large area solid state x-ray detector employs a plurality of cells arranged in rows and columns composed of photodiodes that are charged, exposed to x-rays which deplete their charge in proportion to the exposure, and then recharged to determine the amount of exposure. Fast scanning of the photodiodes consistent with the reduction of dark current effects is obtained without ghost images by employing a non-imaging scan following the imaging scan. The non-imaging scan employs a greater proportion of each scan duration for charge restoration than the imaging scan. In one embodiment simultaneous non-imaging recharging of the photodiodes is performed to substantially reduce this non-imaging time.
