World Radiography Day is celebrated every year on 8 November to mark the invention of X-ray by Wilhelm Roentgen in 1895. X-ray is one of the common imaging tests suggested by a medical expert to get a view of the internal body parts in a non-invasive way. The procedure helps to diagnose certain medical conditions and defects like infection, breakage, swelling and others.
To carry out the X-ray, a medical expert sends X-ray beams through the patient's body and record the result in the form of images on a fluorescent screen.
When the X-ray beams pass through the body, they get absorbed by different parts depending on its density. For example, muscles or fat will show up in grey, bones (or any dense material) will show up in white and air (especially in the lungs) will be seen in black colour. Likewise, any defect in the body part is diagnosed with the help of an X-ray.Types Of X-ray Imaging
