X-Ray Medical Imaging

X-ray is  one of the major diagnostical tools in medicine since its breakthrough by Wilhelm Roentgen. (1895).


*  X-rays cannot be deflected by electric area or magnetic area.

*  X-rays journey in directly lines.
*  Photographic film is blackened by X-rays.
*  X-rays have a high penetrating power.

*  Photoelectric emission can be made by X-rays.
*  Fluorescent materials blaze when X-rays are directed at them.


The radiographic likeness of the X-ray exposure is very resolute by the interaction of the X-rays which are transmitted through the persevering with a photon detector.


Plane film  (bony trauma , car crash..) X-ray charts the total attenuation of X-rays along a route through the body, giving a projection likeness. Nice result for skeletal part structure in accidents.


Production of X-rays 

X-rays are made when quickly going electrons that have been accelerated through a promise difference of alignment 1 kV to 1 MV hits a steel target.(metal).

Electrons from a warm component are accelerated up on a target anode.

Less than % 1 of the power provided is converted into X-radiation throughout this process.
