Medical Fields That Use X-Rays

X-rays are nothing but a part of electromagnetic radiations. However, radiowaves and lightwaves are also part of electromagnetic radiation. But, x-rays, unlike lightwaves, hold the potential to penetrate the body due to higher energy in them.
It has almost been a century when x-rays first got discovered to be used for medical diagnostic purposes. And these have continued to be an important diagnostic tool when it comes to diagnosis or treatment of different illnesses and injuries.
Varied fields that use x-rays:
 

Radiography

 
Radiography is one of the most common x-ray techniques, wherein an x-ray beam is produced using an x-ray machine. This beam is focused at the patient’s body part being tested and then at a special film with a purpose to form an image. Radiography tests are those tests that expose patients to minimum radiation dose, thereby protecting them against any risk.
Mammography is part of radiography, which is conducted in case of diagnosis of breast cancer. While the test poses the patient to a small risk, it helps in early detection of breast cancer, thus saving many lives.
