During which period does a generator in "pulse progressive fluoroscopy" mode produce usable x-ray photons?

In "pulse progressive fluoroscopy" mode, the generator produces usable x-ray photons during the duty cycle. This refers to the portion of the cycle where the x-ray exposure is actively generated for imaging purposes. The duty cycle is the time during which the x-ray tube is energized and producing radiation, allowing for the capture of images in a pulsed format.

This mode is beneficial as it allows for the reduction of patient exposure to radiation while still capturing necessary images. It contrasts with other phases of the pulse sequence, such as the extinction phase, interrogation phase, and recovery phase, where the x-ray production is either not occurring or is in preparation for the next pulse. Focusing on the duty cycle is crucial in understanding the effective imaging intervals and ensuring safety and efficiency in fluoroscopic procedures.
