摘要： An object of this invention is to implement a radiographic apparatus which can stably obtain a moving image at a high speed by suppressing a voltage variation in GND or power supply line and omitting the standby period for each frame. To achieve this object, during a period after electrical signals from conversion elements (S1-1-S1-3) in one control interconnection (G1) are transferred and read for each row by a driving circuit section (SR1) before electrical signals in the next control interconnection are transferred and read, the read-accessed conversion elements are refreshed for each row, thereby eliminating the necessity for preparing a refresh period in acquiring continuous moving images. In addition, since the conversion elements are refreshed for each row, the dark current (transient current) in the refresh mode can be made small as compared to a case wherein all the conversion elements are refreshed at once. With this arrangement, the voltage variation in GND or power supply line is suppressed.

摘要： A radiological imaging apparatus and method corrects fixed pattern noise (FPN) generated within the apparatus and suppresses increases in random noise attendant upon FPN correction to provide radiological imaging having improved reliability and image quality. The apparatus has a signal processing circuit that digitizes analog output from a read-out circuit, four FPN memories for storing four dark outputs, a light memory for storing a light output after X-ray exposure of a subject, a CPU for controlling the signal processing circuit as well as FPN and light memories, and a shift resister 7 controlled by the CPU. The method involves averaging multiple dark outputs and subtracting the FPN data average so obtained from the light output which includes the X-ray imaged to enhance picture quality. Since the FPN correction uses FPN data that has been averaged over multiple dark outputs, the method also suppresses random noise generated by the FPN correction for enhanced imaging accuracy.

摘要： A lamp emits pulse-shaped visible light when a wait period begins. If a radiation emission switch is not pressed in the wait period, X-ray radiation is not emitted from an X-ray source, and no charges are accumulated in photoelectric conversion elements of an X-ray imaging apparatus. In a non-read period, although signals are sequentially read from the photoelectric conversion elements, an output signal does not change. When the radiation emission switch is pressed in synchronization with a radiation-induced signal in a certain wait period, the X-ray source emits X-rays. After irradiation of X-rays, a photoelectric conversion period transitions to an actual read period. In the photoelectric conversion period, X-rays are emitted and transmitted X-ray information of a patient are accumulated in the photoelectric conversion elements of the X-ray imaging apparatus. In the actual read period, the accumulated information is read.

摘要： A plurality of correction images are obtained while changing the radiation energy of an incident radiation in the absence of an object. Subsequently, an object image is obtained in the presence of the object by emitting the radiation to the object. Then, the object image is corrected by using a correction image obtained under a radiation energy condition closest to the radiation energy of the obtained object image.
