Abstract: Systems and methods for generating X-rays. The systems comprise: a voltage generator configured to generate a waveform comprising a plurality of pulses; a plurality of X-ray tubes that are each configured to emit pulses of X-rays responsive to the waveform; and a plurality of connectors that are each configured to be coupled to the voltage generator and communicate the waveform from the voltage generator to the X-ray tube. A dose and/or voltage of the pulses of X-rays is/are tunable in the field by adjusting at least one of (i) a line impedance of the system via an interchange of a first connector with another second connector of the plurality of connectors and (ii) a load impedance of the system via an interchange of a first X-ray tube with another second X-ray tube of the plurality of X-ray tubes.
