In all machines, the x-ray tube output will tend to decrease over time as the tube ages. As the tube ages, metal evaporated from the filament tends to deposit or plate out on the inside of the glass envelope. This thin metal deposit absorbs low energy x-rays and tends to reduce the x-ray output. chrome pc indir

"WebWhere I is intensity and D is distance. Therefore if a dose of 1 gray (Gy) is measured at a distance of 2 m, a dose of 4 Gy will be found at 1 m, and 0.25 Gy at 4 m. Therefore changing the distance between the x-ray tube and patient has a marked effect on beam intensity. Such a change requires a corresponding modification of the kVp or " - How are low dose cabinet x-rays produced
