Scattering Radiation

Radiographic images are maps of radiation absorption, the highest bone, lungs or the air in the lowest absorption sağlar.Radyoloji expert, the contrast between different tissue types must be brought to the highest level.Because of the scattered radiation from the patient, increasing the contrast makes the complex, as a result, disrupt the quality of the image.



Unwanted hair be removed to the Grid Use for narrow and closely built, and among low-absorbing materials as a series of lead tape oluşur.Yalnızca X-ray tube display to the recipient (film or an image intensified Builder) in a straight line reaching radiation, this grid of (grid) is geçebilir.Grid in the lead, on the grid at the rate of incoming radiation will weaken.

The depth of grid strips are only 1 mm and up to 25 centimeters have been compressed into two concentrations.Grid alternative to an air gap kullanmaktır.Bu method, approximately 10-20 cm air gap with the patient image buyers among yerleştirilir.Bu distance, low-energy scattered radiation and image receivers interact with before get rid of him enabling tanır.Hava gap method lung shots widely used .
