The low energy you desire might not be high enough to penetrate the object you want to image, either a weld to inspect, the blacksmiths bespoke object or the human. For imaging human tissue you want high energy for less radiation dose in the patient. That’s why x-rays are filtered by some mm of aluminum before imaging a patient. These filtered lower energy photons would be absorbed in the patient anyways.

1. Perhaps variable power with unintended backscatter emissions detection would be useful to make it safer and more robust.

2. With more sensitive sensors, the imaging power needed can be reduced. This has been the trend in dental X-ray machines. (Orders of magnitude more power were used in developed film-style apparatus.)
