Image detecting device and an X-ray imaging system

An X-ray imaging system, comprising:

• at least one X-ray source;
• a radiation control circuit configured to control a radiating intensity of an X-ray;
• at least one photoelectric element having a capacitor capable of storing electric charge corresponding to a dose of the X-ray when the photoelectric element is irradiated, the photoelectric element being arranged in a matrix array;
• a protecting element intervened between the capacitor and a bias line suppling a bias voltage;
• a scanning circuit configured to apply a scanning signal to a scan line;
• and
• a switching element, intervened between each of the photoelectric elements and a signal line, configured to supply the electric charge stored in the capacitor to the signal line when the switching element is on, the switching element being controlled by the scanning signal.

An X-ray imaging system, comprising:

• at least one device radiating X-ray;
• a first image detecting device comprising at least one first photoelectric element having a first capacitor capable of storing electric charge corresponding to a dose of the X-ray when the photoelectric element is irradiated;
• a second image detecting device comprising at least one second photoelectric element having a second capacitor capable of storing the electric charge corresponding to the dose of the X-ray when the photoelectric element is irradiated;
• a control circuit configured to control a first detecting period for storing the electric charge to the first capacitor, a second detecting period for storing the electric charge to the second capacitor, the first detecting period and the second detecting period being exclusively set;
• and
• a source configured to supply a ground potential to the first capacitor during the second detecting period and to the second capacitor during the first detecting period.

An imaging detecting device, comprising:

• first photoelectric elements and second photoelectric elements arranged in a matrix array,
• at least one first scan line and at least one second scan line arranged alternately;
• a scanning driver for supplying scanning signals to the first scan line and the second scan line;
• first switching elements intervened between respective first photoelectric elements and the first scan line;
• second switching elements intervened between respective second photoelectric elements and the second scan line;
• and
• a scanning circuit controlling the scanning driver, the scanning driver supplying a first signal for enabling the first switching elements to be on during a first period, for enabling the second switching elements to be on during a second period, at least one part of the first period and the second period being overlapped, a second signal for enabling the first switching elements to be off during the first period except the overlapped period, a third signal for enabling the second switching elements to be off during the second period except the overlapped period.
