What is a constant potential generator?
Constant Potential sources use a cathode which includes a filament, whose temperature controls the flow of electrons to the anode. Unlike with pulsed generators, this technology very precisely focalizes the electron beam, which reduces the size of the area emitting X-rays, called “focal spot”.
What are the 2 main functions of the X-ray generator?
An X-ray generator is a device that produces X-rays. Together with an X-ray detector, it is commonly used in a variety of applications including medicine, X-ray fluorescence, electronic assembly inspection, and measurement of material thickness in manufacturing operations.
What are the types of X-ray generator?
Generator types used in fluoroscopy include single phase, three phase, constant potential, and high frequency.
What is the function of the high voltage generator in an X-ray imaging system?
The High Voltage Generator of an x-ray machine is responsible for increasing the output voltage from the auto transformer to the kVp necessary for x-ray production. On High Voltage generator, some heat is generated in the high voltage section and is conducted to oil. The oil is used primarily for electrical insulation.
What is filament boost?
Filament Boost: When an X-ray tube is not producing X-rays (i.e. there is no high voltage applied to the cathode and anode) its filament is in the so called idle (or preheat) mode. It has current running through it but it is below the emission point where tube current would be drawn.
What is high tension generator?
A High Voltage (HV) generator is designed to be a powerful Diesel electricity source, with a high output voltage. A High Voltage generator is the perfect type of Diesel generator for providing electricity in prime, continuous or standby modes across larger construction sites or outdoor areas.
How does a 3 phase generator work?
An AC three-phase generator is simply three AC single-phase generators. These generators run sequentially with an offset of 120° between them taken two at a time. Thus, the generator produces three waves of AC voltage in one cycle facilitating the consistent supply of constant voltage.
What is kVp in radiology?
kVp. The kilovoltage peak (kVp) is the difference in potential applied to the X-ray tube.[11][14] kVp is directly proportional to the average energy of the X-ray spectrum produced, referred to as X-ray quality.[14] kVp plays a role in adjusting the amount of penetration and exposure in an acquisition.
What is the difference between 1 phase and 3-phase generator?
Single-phase generators produce and rely upon one AC flow with one up-and-down cycle, while 3-phase produce and cycle three simultaneously.
Why is there 400V between phases?
Because each phase is phased out by 120°, the voltage between any two phase is 400V.
What is the relationship of kVp and mAs?
The first experiment showed that, when the film density is kept constant, the higher the kVp, the lower the resolution and image contrast percentage; also, the higher the mAs, the higher the resolution and image contrast percentage.
What is a Bucky tray?
A bucky is typically used for table or wall mounted x-ray systems and holds the x-ray cassette and grid. A bucky, is a device found underneath the exam table, a drawer like device that the cassette and grid is slid into before shooting x-ray.
What are mAs and kVp?
The three main components of any x-ray exposure are kVp, mA, and time. * kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. Understanding Technique.
Do I need a single-phase or three-phase generator?
It All Comes Down To Power Needs Single-phase systems are less complex and less costly. They are more common in residential or rural applications where the loads are relatively small. Unsurprisingly, 3-phase systems are more costly to install and maintain, but depending on your power needs, they may be a necessity.
What is a constant potential X ray generator?
LITEX™: Constant Potential X-Ray Generator LITE X™ is a compact, lightweight generator that is also very robust, does not use a radioactive source, has low/no maintenance compared to pulsed x-ray generators and has a much smaller focal spot size, which affords resolution heretofore unavailable in portable systems.
Is Lite X™ a pulsed X-ray generator?
LITE X™ is not a pulsed x-ray generator; rather it is a constant-potential (CP) generator. This affords smaller focal spot, dramatically reduced maintenance and much longer useful life. The LITE X™ generators do not have a fixed duty cycle.
Why choose the Lite x™ constant potential generator?
Because of the characteristic of the LITE X™ constant potential generator and the small focal spot sizes, image resolution is dramatically better than that achieved with a pulsed generator. At FFI Tactical we have consultants and advisors around the world, ready to help you with solutions for your security measures.
What is the difference between Concon constant potential and pulsed generators?
Constant Potential sources use a cathode which includes a filament, whose temperature controls the flow of electrons to the anode. Unlike with pulsed generators, this technology very precisely focalizes the electron beam, which reduces the size of the area emitting X-rays, called “focal spot”.
