X-ray Generators

The X-ray Generators delivers the electrical power to energize the x-ray tube and permit the section of x-ray energy, X-ray quality, and exposure time and dissipation rates specific to a generator and x-ray tube target housing.


An x-ray generator is a device that helps to produce x-ray, together with an  x-ray detector, it is commonly used in a variety of applications including Medicine, x-ray, electronic assembly inspection, and measurement of material thickness in a manufacturing operators.

Types Of X-ray Generators 
• Single Phase Generators 
• Three Phase Generators 
• High-frequency Generators 
• Constant Voltage Generators 

- Single Phase Generators: - (also known as single alternator) is an alternating current electric generator that produce a single, continuously alternating voltage.

- Three Phase Generators: - work by producing three separate waves of AC power that operate in a sequence ensuring that there is always a continuous flow of energy and that’s the power level never dips as it does with single phase generator. Because of this uninterrupted reliability, Three phase generator are much more powerful.

An AC Three Phase Generators 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.

Three Phase Generators: – uses a transformer to the voltage that is applied across the x-ray tube The generator also rectifies the waveform from Alternating Current AC to Direct Current DC.

- High-frequency Generators: - Fully rectify AC current and supply the tube with DC current (High frequency means measuring even up-to 100KHZ instead of standard supply frequency of 50KHZ) The present HF X-ray generators use the frequency inverter-rectifier technology, to produce near constant potential.

Constant Voltage Generators: - Achieve a DC high voltage with minimal ripple through the use of a closed loop linear voltage Controller (e.g. High voltage triodes) in series with the tube, High frame rates and voltage are achieved,
- Constant potential generator use a complex technology with high cost investment and operation, and consequently have lost popularity.

HAND X-RAY

The basic projections are P.A and Lateral , ➢ Postero anterior (Dorsi-palmar P.A):- The patient is seated along side the table, the forearm is placed pronated on the table with the palmar surface of the hand in contact with the cassette. With the fingers slightly separated and extended to ensure that they remain in contact to the cassette. Centering point: - Center to the head of the third metacarpopalangeal joint. ➢ Dorsi-palmar oblique: - From the PA position the patient will now rotate his/her hand approximately 45° degrees, ➢ Another modified 15° degrees, Centering point: - Center to the 4th metacarpal bone. Essential image characteristics, The image should demonstrate the bones clearly and soft tissue outline no rotation or motion. References: MIT. Abdussalam A.

DARKROOM ILLUMINATION

 Darkroom Illumination: - dividend into 2 ordinary white light and safe light. White light is important because of the following  • To inspect and maintain cassette and screens • Cleaning of all work surfaces and floors  • And to services the processors  Sitting of the white light  * Sited close to the ceiling (to avoid casting strong shadow) * Moderate in intensity (60W tungsten or 30W fluorescent) (accommodation easier after safe light) * Centrally place or otherwise  All films get fogged when exposed by the white light  Safe Light  A safe light is a red light bulb situated in a darkroom at a distance of 1.2m (4 ft) off the working surface and use for a processing purpose. And a colored lighting which provides sufficient illumination by which one can handle, manipulate and process film with no significant fogging occurring,  These ensure loading and unloading of x-ray cassette much easier and provides pleasant working condition for the pers...

WRIST X-RAY

The basic projections are P.A and Lateral  ➢ Postero anterior (P.A):- The patient is seated along side the table with the affected side in contact with the cassette. Flexed the elbow joint and the arm is abducted, so that the anterior aspects of the forearm and the palm of the hand should be in contact with the cassette. The fingers are slightly separated to bring the anterior aspects of the wrist in contact to the cassette. Centering point: - Center mid way between the median and lateral styloid process.  ➢ Lateral: - from the postero anterior the wrist is rotated externally to bring palm of the hand vertically, the hand is rotated externally slightly further to ensure that the radial and styloid process are superimposed. Centering point: - Center to the lateral styloid process. Radiological consideration, The radiograph should demonstrate the all of the carpal bones clear and part of the metacarpal and forearm.
