摘要： It is made possible that, in accordance with a plurality of radiographing modes such as the still image radiographing mode and the moving image radiographing mode, the outputs both in the irradiation period and in the non-irradiation period are made to fall within the dynamic range of the radiographing system, whereby an accurate, high-S/N-ratio X-ray radiographic image is obtained. For that purpose, in accordance with the plurality of radiographing modes, an arithmetic operation unit adjusts a power source to control voltage to be applied to a reading circuit unit or an Analogue-Digital conversion unit, such that, in each of the radiographing modes, both an electric signal in the X-ray irradiation period and an electric signal in the X-ray non-irradiation period fall within the dynamic ranges of the reading circuit unit and the Analogue-Digital conversion unit.

摘要： At least one exemplary embodiment is directed to a radiography apparatus configured to have an offset reading period, where during the offset reading period an offset reading operation is performed without illumination by radiation (e.g., X-rays). The offset reading period can be different from a radiation (e.g., X-ray) reading period in timings of applying a gate pulse. During the offset reading period, a pixel addition can be performed such that the switching elements corresponding to two or more lines are concurrently turned on-off thus reducing the offset reading period.

摘要： A radiological imaging apparatus and method allows an operator to select between moving-picture imaging and still-picture imaging modes using the same apparatus so to provide radiological imaging having a picture quality equal to that of conventional radiological film imaging techniques but with a smaller, lighter and more compact equipment configuration. The apparatus employs photoelectric converters arranged in a two-dimensional matrix array for converting radiation into electrical signals, a read-out circuit for reading the signal output from the photoelectric converters, variable gain amplifiers upstream of an analog multiplexer and a buffer amplifier downstream of the multiplexer for outputting serially converted signals. The method involves setting the moving-picture mode gain Gf so as to be greater than the still-picture mode gain Gs, in order to obtain sharper images without exposing the subject to unnecessarily high levels of radiation.

摘要： A correction process is performed using different gain correction signals (GSA, GSB) in accordance with radiographic modes (moving image radiographic mode/still image radiographic mode) set in an X-ray imaging apparatus, respectively. This makes it possible to acquire an image with decreased correction errors even when the X-ray imaging apparatus is configured using an imaging unit having different gain characteristics in the still image radiographic mode and moving image radiographic mode.
