Systems and methods for a high voltage generator of an interventional imaging system

An imaging system, comprising:

• a high voltage generator configured to supply voltage to an X-ray tube including a gridding electrode;
• and
• a controller storing instructions in memory executable by one or more processors of the controller to:
• receive a command signal specifying a respective time at which the high voltage generator is to be activated to initiate each of a plurality of X-ray pulses, including a first time to initiate a first X-ray pulse of the plurality of X-ray pulses and a second time to initiate a second X-ray pulse of the plurality of X-ray pulses following the first X-ray pulse;
• activate the high voltage generator at the first time, and initiate the first X-ray pulse by commanding the gridding electrode to open after the first time;
• close the gridding electrode and deactivate the high voltage generator upon completion of the first X-ray pulse;
• and
• activate the high voltage generator at the second time, and initiate the second X-ray pulse by commanding the gridding electrode to open after the second time.

A method for an interventional imaging system including a high voltage generator configured to supply voltage to an X-ray tube, the X-ray tube including a gridding electrode, the method comprising:

• performing a first X-ray pulse of a plurality of X-ray pulses of an imaging procedure, including activating the high voltage generator before opening the gridding electrode to initiate the first X-ray pulse and closing the gridding electrode to terminate the first X-ray pulse;
• deactivating the high voltage generator upon completion of the first X-ray pulse;
• and
• reactivating the high voltage generator and then opening the gridding electrode to perform a second X-ray pulse of the plurality of X-ray pulses, wherein the second X-ray pulse is performed after the first X-ray pulse with no other X-ray pulses between the first X-ray pulse and the second X-ray pulse, and wherein the high voltage generator is reactivated one or more times between the first X-ray pulse and the second X-ray pulse to maintain a voltage of the high voltage generator above a lower threshold.
