What do you see on an x ray
X-rays are types of electromagnetic radiation probably most well-known for their ability to see through a person's skin and reveal images of the bones beneath it. Advances in technology have led to more powerful and focused X-ray beams as well as ever greater applications of these light waves, from imaging teensy biological cells and structural components of materials like cement to killing cancer cells. X-rays are roughly classified into soft X-rays and hard X-rays. Soft X-rays have relatively short wavelengths of about 10 nanometers a nanometer is one-billionth of a meter , and so they fall in the range of the electromagnetic EM spectrum between ultraviolet UV light and gamma-rays.

What Irregularities Can an X-Ray Detect?
X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white.
This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black. The most familiar use of x-rays is checking for fractures broken bones , but x-rays are also used in other ways.
For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer. When you have an x-ray, you may wear a lead apron to protect certain parts of your body. The amount of radiation you get from an x-ray is small. For example, a chest x-ray gives out a radiation dose similar to the amount of radiation you're naturally exposed to from the environment over 10 days.

X-rays and Other Radiographic Tests for Cancer
X-rays are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body. One type of x-ray detector is photographic film, but there are many other types of detectors that are used to produce digital images. The x-ray images that result from this process are called radiographs.
X-rays and other radiographic tests help doctors look for cancer in different parts of the body including bones, and organs like the stomach and kidneys. Contrast studies may require more preparation ahead of time and may cause some discomfort and side effects, depending on what kind you are having. For names of contrast studies, see Table 1. Radiographs, most often called x-rays, produce shadow-like images of bones and certain organs and tissues. X-rays are very good at finding bone problems.

Type a minimum of three characters then press UP or DOWN on the keyboard to navigate the autocompleted search results. An x-ray examination creates images of your internal organs or bones to help diagnose conditions or injuries. A special machine emits puts out a small amount of ionising radiation. This radiation passes through your body and is captured on a special device to produce the image. The dose of radiation you will receive depends on the area of your body being examined. Smaller areas such as the hand receive a lesser dose compared to a larger area such as the spine. On average, the dose of radiation is roughly the same as you would receive from the general environment in about one week. Tell your doctor if you are pregnant or think you may be pregnant.
Tour of the Electromagnetic Spectrum
X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation.
Learn about our expanded patient care options for your health care needs. X-rays use invisible electromagnetic energy beams to make images of internal tissues, bones, and organs on film. Standard X-rays are performed for many reasons. These include diagnosing tumors or bone injuries.
Radiologists often use X-ray technology to take pictures of the organs inside your body. Your doctor will have ordered that X-rays be taken of a certain area of your body so they can evaluate a particular health issue. This is the most commonly used form of imaging for diagnostic purposes.
X-rays As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength. This is partially because X-rays have very small wavelengths. It is also because X-ray light tends to act more like a particle than a wave.
What Are X-Rays?
X-rays are a type of high-energy radiation. An X-ray machine can produce short bursts of X-rays. The rays pass easily through fluids and soft tissues of the body. However, dense tissue such as bone will block some of the X-rays. Density means how much of something there is in a certain amount of space.
Most of us know what the basic purpose of an X-ray is. In reality, X-rays can be used to detect and monitor conditions ranging all the way from a minor bone chip to advanced stages of cancer. This radiation can pass through the skin instantly, but is absorbed in different ways once it gets inside the body and starts contacting other objects. Bones or other thick materials contain the most density, and they appear white and opaque in an X-ray. Air in the lungs appears black, and medium-density areas like muscles and tendons appear gray.

Back to Health A to Z. They can't be seen by the naked eye and you can't feel them. A detector on the other side of the body picks up the X-rays after they've passed through and turns them into an image. Softer parts that X-rays can pass through more easily, such as your heart and lungs, show up as darker areas. X-rays can be used to examine most areas of the body.
