    摘要： A radiation image apparatus without synchronous communication includes a pixel circuit, a reading circuit, a drive control circuit, an image processing circuit, a time measuring circuit, and a management circuit. The pixel circuit includes an imaging element configured to generate image data based on radiation and a detecting element configured to generate irradiation data of irradiation with the radiation. The reading circuit is configured to read the image data and the irradiation data. The drive control circuit is configured to control a first time when the image data is read by the reading circuit. The image processing circuit is configured to perform correction of the read image data. The time measuring circuit is configured to measure a second time related to the irradiation with the radiation based on the irradiation data. The management circuit is configured to manage the correction based on the first time and the second time.

    摘要： A detector, comprising: a plurality of first pixels, each first pixel configured to convert radiation into an electrical signal; a plurality of second pixels; and a plurality of data lines coupled to the first pixels and the second pixels; control logic configured to combine a signal from at least one of the second pixels with an electrical signal from one of the first pixels; wherein electrical connections of each of the second pixels are different from electrical connections of the first pixels such that for each second pixel: components of the second pixel are different from components of each of the first pixels; electrical connections between components of the components of the second pixel are different from electrical connections between the components of each of the first pixels; or a number of electrical connections to the second pixel are different from a number of electrical connections to each of the first pixels.

    摘要： An intra-oral imaging device includes: an imager that detects radiation transmitted through an object while being placed in an oral cavity; and a controller that controls the imager while being placed outside the oral cavity. The imager includes an image sensor including a plurality of pixels for acquiring an image of the object. While power is being supplied to the controller, the controller supplies power to the image sensor in an imaging period during which the image sensor performs imaging and stops supplying the power to the image sensor in a standby period during which the image sensor is on standby.
