Figure 1.
The timing diagram of the flat panel and the x-ray pulses. During each frame the flat panel is ready for x-ray exposure for about 18 ms (E), then, there is a 15 ms interval (R) for readout of the flat panel. The low (L) and high (H) energy x-ray pulses are synched with the flat panel to avoid x-ray exposure during the readout of the flat panel.
