What are the main components of an X-ray machine?
An X-Ray machine consists of two main components – X-Ray generator and an image detection system. An X-Ray tube essentially is a high-vacuum diode consisting of a Cathode and Anode. X-ray tube operates by generating a stream of electrons by heating up a cathode (tungsten) filament.
What voltage does an X-ray machine use?
220 volt
In most clinics and hospitals, a standard 220 volt current supplies power to the x-ray machine. The transformer raises the voltage to 100,000’s of volts, the amount of energy necessary to produce x-rays. When the x-ray technologist selects a certain kVp setting, the transformer adjusts the current accordingly.
What are XRAY parameters?
The four main exposure parameters are tube potential (kV), tube intensity (mA), exposure time (s) and focus to detector distance (cm). Exposure time and tube intensity could be a unique exposure factor (mAs).
What is the size of an X-ray machine?
Larger panels are typically 14” × 17” while smaller panel detectors come in four common sizes—11” × 14”, 8” × 12”, 24 cm × 30 cm, and 25 cm × 30 cm. Although it is possible to use both larger and smaller panels in conjunction with one mobile X-ray unit, doing so will increase the price of the unit dramatically.
What is Xray control panel?
X-ray control panel means a device which controls input power to the X-ray high-voltage generator and the X-ray tube. It includes equipment such as timers, phototimers, automatic brightness stabilizers, and similar devices, which control the technique factors of an X-ray exposure.
How many watts is an xray?
–X-ray generators use up to 100 kW of electrical power, or the power required for ~30 U.S. households. FIGURE 1.1 At the negatively charged plate, the electron has potential energy of 1 eV, which is converted into a kinetic energy of 1 eV as the electron is accelerated from the cathode to the anode.
What is the kVp?
kVp stands for kilovoltage peak. 116,117. This is the highest voltage (measured in thousands of volts) that will be produced by the x-ray machine during an exposure. For example, if 60 kVp is selected, 60 kilovolts (60,000 volts) is the maximum strength of x-rays produced in this exposure.
