Virtually all current x ray generators in radiology departments use three phase power supplies.
Three phase generator x ray.
Table 1 3 relative radiation intensity as a function of distance from the radiation source inverse square law a generator uses a transformer to increase the voltage that is applied across the x ray tube.
Three phase generators rectifier circuit inverts negative voltage sends highest of 3 phases to x ray tube to x ray tube input 3 phase voltage rectified 55.
In the development of x ray systems there are three major trends affecting the high voltage generator.
What is better for a three phase generator vs.
It has more efficient x ray production.
Three phase generators produces nearly constant potential much higher tube ratings than single phase more efficient than single phase shorter exposures high repetition rates.
Hf generator is found to be approximately two times more efficient has better reproducibility and produces sharper better quality images than single phase three phase generator.
The invention relates to a three phase x ray generator comprising a three phase transformer having secondary windings which are connected to the x ray source via a rectifier circuit the high.
Single phase three phase high frequency capacitor discharge mobile units battery operated mobile units not much used falling load where is the capacitor type generator used.
In order to obtain similar film optical density and or to obtain similar radiation dose the hf x ray generators require less exposure time nearly half to 2 3 rd as compared to single phase sp generators due to constant potential and radiation.
The discrete portion of the x ray emission spectrum would change position with a change in.
Requires less mas than a sigle phase full wave generator.
The x ray generator provides three things that are required to produce x rays and they are a source of electrons a means of acceleration and a target for interaction.
In the portable x ray machine.
The three main parts to an x ray generator setup are an x ray tube a high voltage power supply and a control unit.
Higher ratings for ma and kvp can set technique higher and exposure times are as short as 1 msec.
Because of this uninterrupted reliability three phase generators are much more powerful.
