An X-ray detector capable of independently controlling a read-out rate for each region, an X-ray imaging apparatus having the same, and a method of controlling the same are provided. The X-ray detector includes a plurality of pixels which are two-dimensionally arranged and configured to output an electrical signal corresponding to incident X-rays, a plurality of gate lines configured to connect the plurality of pixels in a row direction, a plurality of data lines configured to connect the plurality of pixels in a column direction, a read-out circuit configured to read out the electrical signal generated by the plurality of pixels through the plurality of data lines, and a switcher configured to independently turn connections between the respective data lines in the plurality of data lines and the read-out circuit on and off.

A position-sensitive ionizing-radiation counting detector includes a first substrate and a second substrate, and a defined gas gap between the first substrate and the second substrate. The first and second substrates comprise dielectrics and a discharge gas is contained between the first and second substrate. A microcavity structure comprising microcavities is coupled to the second substrate. An anode electrode is coupled to the first substrate and a cathode electrode is coupled to the microcavity structure on the second substrate. The detector further includes pixels defined by a microcavity and an anode electrode coupled to a cathode electrode, and a resistor coupled to each of the cathode electrodes. Each pixel may output a gas discharge counting event pulse upon interaction with ionizing-radiation. The detector further includes a voltage bus coupled to each of the resistors and a power supply coupled to at least one of the electrodes.

A detector arrangement for detecting at least one of rays, ions and particles includes a plurality of detectors. Each detector has a respective anode output and the detectors are arranged with the respective anode outputs being in an electrical series. The arrangement includes a plurality of resistive elements interspersed in the electrical series. The arrangement includes a first measurement point at a first end of the electrical series and a second measurement point at a second end of the electrical series. The arrangement includes electrical circuitry, electrically connected to the first and second measurement points for receiving electrical signals/pulses from the first and second measurement points, and for using the electrical signals/pulses from the first and second measurement points to determine which of the plurality of detectors made the detection utilizing a division of charge that exists between the first and second measurement points.
