    • A portable radiation image capturing apparatus is described. In the portable radiation image capturing apparatus multiple image capturing elements are two-dimensionally arranged, the apparatus is provided with a current detecting means for detecting a current flowing in the apparatus, a read-out circuit having a power supply mode in which the charge generated in each image capturing element can be read out and converted into an electric signal and a stand-by mode in which charge is not read out and power is consumed less than in the power supply mode, and a control means for causing the read-out circuit to change from the stand-by mode to the power supply mode when detecting start of irradiation with radiation on the basis of an increase in the current value detected by the current detecting means while the read-out circuit is in the stand-by mode.

    • An apparatus for obtaining an intraoral x-ray image from a patient has an x-ray source and an intraoral image detector comprising one or more detectable elements. One or more sensors are positionally coupled near the x-ray source and are energizable to sense the location of the one or more detectable elements when the intraoral image detector is within the patient's mouth. A control logic processor is in signal communication with the one or more sensors and is responsive to stored instructions for calculating a detector position of the intraoral image detector. A projector is positionally coupled to the x-ray source and is in signal communication with the control logic processor and is energizable to project an image toward the calculated intraoral image detector position in response to signals from the control logic processor.

    • A personal radiation dosimeter may comprise a housing that is substantially light-impermeable. The housing contains a radiation energy sensitive component (RESC) that is transported by a user. A reader has ingress and egress for the housing, and an internal stimulation light to photo-stimulate the RESC. An internal photosensor senses photons from the RESC after photo-stimulation and generates a signal. The photosensor may convert and amplify the RESC signal into a signal corresponding to the amount of radiation. A processing circuit may be used to assess an amount of radiation incident on the RESC based on the signal. In addition, the reader may contain a reset light to reset the RESC for reuse after the amount of radiation is detected.
    • 个人辐射剂量计可以包括基本上不透光的壳体。 外壳包含由使用者运送的辐射能量敏感元件(RESC)。 阅读器具有入口和出口的外壳,以及内部的刺激光,以激发RESC。 内部光电传感器在光刺激后感应RESC的光子并产生信号。 光电传感器可以将RESC信号转换并放大成对应于辐射量的信号。 可以使用处理电路来基于该信号来评估入射在RESC上的辐射量。 此外,读取器可以包含复位光,以在检测到辐射量之后重置RESC以重新使用。
