Increasing the kVp in x-ray production raises the energy of electrons, resulting in a higher intensity of x-ray photons due to increased Bremsstrahlung radiation. This process generates a continuous spectrum of x-rays, while also enhancing the intensity of characteristic x-rays as more electron transitions occur. Despite this increase, only about one percent of the energy input is converted into x-rays. The discussion emphasizes the relationship between tube voltage and photon production, highlighting the efficiency of energy conversion in x-ray systems. Understanding these dynamics is crucial for optimizing x-ray imaging techniques.

Why does increasing the kVp in x-ray production increase the number of x-ray photons if the number of electrons produced by the cathode is unchanged? thanks

i think the increase in tube voltage accelerates the electrons to higher energy and radiation from accelerated/decelerated charge "Bremsstrahlung" increases thus increasing the x-ray intensity/number of photons-these radiations are of continuous nature and fall in the range of continuous x-rays. however the characteristic x-rays which are characteristic of the target -also increases in intensity as number of transitions increases - hardly one percent of the energy input gets out as x-rays.
