WHAT IS  CHARACTERISTICS OF  X-RAY IMAGE ??

   

•  The two dimensional likeness I(x, y) of the three dimensional distribution of the X-ray attenuating body tissue of the persevering can be described as a function of the primary photon intensity N of power E, the power absorption effectiveness of the image receptor  e E) (film) and the attenuation coefficients m  which have to be considered along the photon path in z-direction.

• As higher the attenuation coefficient, as bigger absorption, as lower the last power of the image.

• For skeletal part tissue the attenuation coefficient is substantially bigger than for soft body tissue, therefore bigger absorption.
