how x ray is done?

The machine sends a beam of radiation through your body. Your hard, dense bones block that beam, so they show up as white on the film below you. The radiation also goes through softer tissue like muscle and fat, which appear in shades of gray in the X-ray. The air in your lungs will look black in the image.

A radiologist or X-ray technician will perform the sinus X-ray. You may be asked to sit or lie down on an X-ray table. The radiologist next places a lead apron over your torso to help protect you from radiation. They then place your head in line with the X-ray machine.

An x-ray is way to create a picture of the structures inside of the body using a small amount of radiation. It can help the doctor find a tumor. For small bowel cancer, x-rays may be taken of the entire gastrointestinal system, including the esophagus, stomach, small bowel, large intestine, and rectum.

X-rays are high-frequency, and thus high-energy, electromagnetic radiation. They have wavelengths ranging from 0.01 to 10 nanometres, and thus frequencies from 3×1019 to 3×1016 Hz.

The X-ray usually takes about a minute per image. You may get more than one image during a visit.

X-rays are just like any other kind of electromagnetic radiation. They can be produced in parcels of energy called photons, just like light. There are two different atomic processes that can produce X-ray photons.

An x-ray examination uses an electrical device to emit (put out) x-rays and digital technology to create two-dimensional pictures of internal body structures. This test is particularly useful in diagnosing conditions or diseases that affect the bones and chest.

During the front view, you stand against the plate, hold your arms up or to the sides and roll your shoulders forward. The X-ray technician may ask you to take a deep breath and hold it for several seconds. Holding your breath after inhaling helps your heart and lungs show up more clearly on the image.

X-rays are a very energetic form of electromagnetic radiation that can be used to take images of the human body. 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.

Chest x ray. 5. ... A PA radiograph is obtained with the x-ray traversing the patient from posterior to anterior and striking the film. Similarly an AP radiograph is positioned with the xray traversing the patient from anterior to posterior striking the film.

Radiology is a medical specialty that uses imaging to diagnose and treat diseases seen within the body. ... The radiology department may also be called the X-ray or imaging department. It is the facility in the hospital where radiological examinations of patients are carried out, using the range of equipment listed above.

X-ray technology is one of the oldest and most common forms of medical imaging used by doctors. X-rays are a form of electromagnetic radiation that send small waves through the body, which are then absorbed in different amounts depending on the materials they pass through.

X-rays produce high-resolution, two-dimensional images and provide a quick, low-cost means of assessing bone and joint disease and soft-tissue calcification. Radiography is still the first imaging tool used to assess suspected bone pathology, before other imaging modalities such as MRI or CT.

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 process itself usually takes around 10 minutes. Once the x-rays have been taken, the film will be then processed in less than half an hour, and the images passed on to your vet. Digital x-rays are generally ready for viewing instantly.

X-rays work just like visible light (in fact they're just a higher energy form of light) in that they are able to pass straight through some materials (just like light passes through glass) but not through others (just like light doesn't get through walls).
