#Two types of grids in radiology generator

In computed tomography (CT scanning), an X-ray source and its associated detectors rotate around the subject, which itself moves through the conical X-ray beam produced.

The generation of flat two-dimensional images by this technique is called projectional radiography. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). A certain amount of the X-rays or other radiation are absorbed by the object, dependent on the object's density and structural composition.

To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. Similar techniques are used in airport security, (where 'body scanners' generally use backscatter X-ray). Applications of radiography include medical ('diagnostic' radiography and 'therapeutic') and industrial radiography. Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.
