 In 1895 an accidental invention made by Wilhelm Roentgen made the unimaginable possible: doctors for the first time were allowed to peer inside the human body without surgery or autopsy.

Since then X-ray has become a standard diagnostic imaging technique all over the globe.

X-ray is basically electromagnetic energy passed through the body. Some particles of the X-ray are blocked by dense structures of the body, for example bones, and will appear white. Metallic parts also appear white as a consequence of the electromagnetic waves being unable to pass through. On the other hand, structures containing air are seen black in the resulting film or image, while muscle, fat and fluid show as shades of gray.

How is the X Ray Scanner Used?

X-ray tests are performed in the radiology department of a hospital or other health care facility. The patient is positioned inside the x ray scanner depending on the type of test. For instance, chest x ray requires the patient to be lying in the back, and the x ray scanner will take images from neck to hips only. In some cases, several angles may need to be scanned.

It is important that you stay still during the x-ray, as movement can cause blurred images, just like in a photography camera. The radiologist in charge will ask you to hold your breath and avoid moving for a few seconds while the image is taken, otherwise the process will have to be repeated.

The inner X-ray landscape of the body is usually recorded on a film or in digital format.

Depending on the type of x-ray, the health care team will decide if pregnant women are allowed to have the test and if metal parts should be removed. The procedure does not involve any pain or discomfort.x-ray_Small

Some common risks associated with x-ray are related to radiation exposure. Children and babies inside the womb are highly sensitive to radiation. Depending on the type of scan (for instance in a chest x ray) the risk may be noteworthy and the procedure should be avoided.

Some Common Uses of X-Ray

X-ray is highly efficient at diagnosing and screening various conditions. Furthermore, surgeons use the x ray scanner during therapeutic procedures to help guide the equipment to the area to be treated.

X-ray can be used for diagnosing bone related problems, including:

  • fractures and breaks
  • problems with teeth
  • osteoporosis
  • osteomyelitis
  • scoliosis or abnormal curvature of the spine
  • bone tumors

Chest x ray is an efficient way to detect abnormalities in the heart, major arteries and lungs. X ray scanner can help diagnose:

  • Heart conditions
    • heart failure
    • congenital heart disease
    • pericarditis
  • Lund conditions
    • pneumonia
    • lung cancer
    • chronic obstructive pulmonary disease (COPD)
