What is the significance of impulse response in DXR systems?

In DXR (Digital X-Ray) systems, the impulse response is crucial because it characterizes how the system reacts to an instantaneous input signal or a transient event. This response effectively illustrates the system's ability to detect and render brief changes in the incoming X-ray signal, which is vital for accurately capturing high-frequency detail in the images. By measuring this response, one can derive important parameters such as the system's bandwidth and overall fidelity, which influence image clarity, sharpness, and contrast. Thus, the impulse response is deeply tied to the performance of the imaging system in terms of how well it can respond to rapid fluctuations in exposure, ultimately affecting the diagnostic quality of the images produced.
