Abstract: The present inventors have recognized that fall times between high-kV to low-kV levels (during a “dual energy” or “fast-kV” energy scan) are linked to the discharge of HV (high voltage) capacitance. In an embodiment of the invention, a high voltage generator may be activated during fall transitions from first to second energy levels in order to substantially maintain a predetermined fall transition time. Accordingly, substantially equal energy distributions between high-kV and low-kV levels may be achieved.

Abstract translation: 本发明人认识到，在高kV至低kV电平之间（在“双能量”或“快速kV”能量扫描期间）的下降时间与HV（高电压）电容的放电有关。 在本发明的一个实施例中，高压发生器可以在从第一到第二能级的跳变转变期间被激活，以便基本保持预定的下降转变时间。 因此，可以实现高kV和低kV电平之间的基本上相等的能量分布。
