How do X rays work
This beam travels through the air, comes into contact with our body tissues, and produces an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them. Dense materials inside our bodies, like bones, absorb the radiation.
How to produce an x ray image
For medical applications, x-rays are usually generated in vacuum tubes by bombarding a metal target with high-speed electrons and images produced by passing the resulting radiation through the patient’s body on to a photographic plate or digital recorder to produce a radiograph, or by rotating both source and detector
Advantages and disadvantages of X rays
One advantage of X-rays is that they are cheaper than similar medical procedures. If a patient requires a medical scan, an X-ray costs health insurance plans less than a MRI or a CT scan. It is also cheaper for a hospital or a doctor’s office to maintain a X-ray machine than an MRI or CT scan machine.
One disadvantage of X-rays is that they do not give detailed images of the body. MRI or CT scans are excellent tools if the doctor is trying to find a medical issue with organs, bone, the brain, and tissues. X-rays do not give any sort of medical data for organs or tissues, only an image of bones.
