X-ray machine is the equipment of producing X-rays and it is mainly consists of X-ray tube and x-ray machine power. X-ray tube includes cathod, anode and vacuum glass tube. But x-ray machine power can deliver into high voltage power supply and filament power, among of them, filament power use fiber filament to heat and high-pressure output terminal of high voltage power supply is installed on both ends of the filament anode and cathode. You must provide a high-pressure electric field and make active electronic of filament accelerate to flow to the anode target and form a high-speed currents

After hitting anode target surface, the 99% electronic transfer to heat and the 1% tuen into X-rays because of compton effect

 The four factors of affecting image effect

 Density-mAs

Contrast-kVp

Sharpness-motion

Distortion- position

X-ray machine application field: X-ray machine is widely applied in every field of medical health, science education and industry, such as current advanced medical equipments, Digital Radiography, High Frequency Radiography Unit can help doctors diagnosis disease better; In industry, it can use in nondestructive inspection.
