An X-ray machine is a medical imaging device that uses X-rays to create images of the inside of the body. X-rays are a form of electromagnetic radiation that can pass through most materials, including the body. When X-rays pass through the body, they are absorbed by different tissues to different degrees. The more dense the tissue, the more X-rays it absorbs.
The images produced by an X-ray machine show the different tissues in the body as shades of gray. The darker the shade, the more X-rays the tissue has absorbed. Bones appear white on X-rays because they are very dense and absorb a lot of X-rays. Soft tissues, such as muscle and fat, appear gray. Air appears black because it absorbs very few X-rays.
X-ray machines are used to diagnose a wide variety of conditions, including broken bones, tumors, and pneumonia. They are also used to guide procedures, such as inserting needles or catheters.
X-ray machines are a safe and effective imaging tool, but they do expose the patient to radiation. The amount of radiation exposure is usually very low, but it is important to talk to your doctor about the risks and benefits of having an X-ray.
