In a radiation therapy system, therapeutic X-rays are delivered to a target volume, while imaging X-rays are also delivered to the target volume for generating image data of the target volume. That is, during an imaging interval during which imaging X-rays are delivered to the target volume, one or more pulses of therapeutic X-rays are also delivered to the target volume. In each pixel of an X-ray imaging device of a radiation therapy system, image signals are accumulated during portions of an imaging interval in which only imaging X-rays are delivered to a target volume, and during pulses of therapeutic X-rays, image signals are prevented from accumulating in each pixel. 在放射疗法系统中，治疗X射线被递送到靶标体积，同时，成像X射线也被递送到靶标体积以用于生成靶标体积的图像数据。即，在成像X射线被递送到靶标体积的成像间隔期间，治疗X射线的一个或多个脉冲也被递送到靶标体积。在放射疗法系统的X射线成像设备的每个像素中，图像信号在成像间隔的各部分期间进行累积，在成像间隔中，只有成像X射线被递送到靶标体积，并且在治疗X射线的脉冲期间，图像信号被防止在每个像素中进行累积。
