What is x-ray or Radiography?

Medical radiography is a broad concept that encompasses many forms of experiments that include the use of x-ray methods to image the internal sections of a body. The radiography means a technique for generating and recording an x-ray pattern in order to provide the user with a static image after the exposure has been terminated. It differentiates itself from the fluoroscopy, mammography, and computed tomography. Radiography may also be used when planning treatment with radiation therapy.

Radiography is specially designed to examine as well as treat patients through recorded images of the body’s internal structure to evaluate the presence or absence of disease, structural or anomaly damages, and foreign objects.
During an X-ray or radiographic procedure, a light beam is passed through the body. A portion of the x-rays or radiography are scattered by the internal structure,also the remaining x-ray pattern is transmitted to a detector so that an image of body parts can be recorded for later evaluation.

History of X-rays

X-rays were found in 1895 by the professor at the University of Würzburg in Germany, Wilhelm Conrad Roentgen. Roentgen found crystals around a high-voltage cathode-ray tube showing a fluorescent light, except though he covered them with a dark cloth, according to the “History of Radiography” of the Nondestructive Research Centre. The tube which penetrated the paper and caused the crystals to shine was producing some form of energy. Roentgen named “X-radiation” the unseen light. Tests revealed that this radiation could reach soft tissue, but not bone, which would create shadow effects on photographic plates.
Roentgen was awarded the very first Nobel Prize in Physics for this discovery, in 1901.

Usage of radiography

Radiography is used in certain kinds of tests and procedures where a static image archive is required. Certain examples include-:

  • Chiropractic examinations
  • Dental examination
  • Spot film or static recording during fluoroscopy
  • Examination of correct placement of surgical markers before performing invasive procedures
  • Orthopedic evaluations
  • Mammography


Radiography is a type of x-ray treatment that holds the same danger categories as other techniques for x-rays. Depending on the particular treatment, the radiation dosage the patient gets differs but is usually smaller than the one obtained during fluoroscopy and computed tomography.

Benefits of X-ray

  • Determining when surgery is needed
  • Reducing the need for investigational surgery
  • Effective detection and management of cancer
  • Reduces hospitalization time
  • Guidance on treating common conditions such as injury, heart disease, and stroke
  • Improving the placement of patients in appropriate care areas, like an intensive care unit.

The major risks associated with x-ray are the small potential of -:

  • Developing cancer that causes radiation or cataracts sometime later in life
  • Disturbance in the growth or development of an embryo or fetus (teratogenic defect) during pregnancy or childbearing.

Moreover, the advantage of radiography when a patient has a medical need much outweighs the slight chance of cancer associated with the treatment. And if the radiography is absolutely required, the lowest maximum sensitivity and the least amount of photos will be used.

    When do I contact the doctor?

    You need to consult the doctor immediately in case of seizures and blackouts. While some of these symptoms may be a result of other medical condition, it is always advisable to receive immediate medical attention. Repeated seizures can cause serious injury and must never be ignored.
