1. A method for performing a dual energy subtraction imaging process on a fluoroscopy imaging system, the method comprising the steps of:
a. operating a radiation source of the fluoroscopy imaging system to obtain a number of high energy (HE) frames;
b. forming an HE image from the number of HE frames;
c. operating the radiation source of the fluoroscopy imaging system to obtain a number of low energy (LE) frames;
d. forming an LE image from the number of LE frames; and
e. employing the HE image and the LE image in a dual energy subtraction imaging process,
wherein the step of operating the radiation source of the fluoroscopy imaging system to obtain the number of HE frames comprises operating the radiation source of the fluoroscopy imaging system in a pulsed manner to obtain the number of HE frames, and wherein the step of operating the radiation source of the fluoroscopy imaging system in a pulsed manner to obtain the number of HE frames further comprises reading a detector between pulses to obtain the number of HE frames.
