are used to diagnose a wide range of illnesses and injuries, including musculoskeletal injuries, chronic joint disease, cancer, abdominal abnormalities, sinus disease, spinal problems and other abnormalities. It is a quick and safe procedure allowing to make an initial diagnosis before the treatment, or more complex and expansive examination. The X-rays are performed with you either standing, sitting or lying on the examination table, depending on the area being imaged. Patients are requested to bring their referral form and give it to the receptionist before their examination.
Today x-ray is used to diagnose a wide range of medical conditions:
What are the benefits and risks of a digital X-ray?
There is little reason to worry about the small amount of radiation you will be exposed to when you receive a digital X-ray. The radiation from modern digital X-ray equipment is significantly lower than it is used to be on a conventional analogue equipment. Immediate image viewing helps with efficient diagnosis and patient care.
X-Rays are produced inside the x-ray tube, when electrons strike a metal target.
The electrons are accelerated from the heated filament and directed by a high voltage towards the metal target (usually tungsten). The collision of the accelerated electrons with the atoms and nuclei of the tungsten target results in production of X-Rays.
A radiograph is an image obtained by placing a part of the patient in front of an X-ray detector and then illuminating it with a short X-ray pulse. Calcium, which is contained in the bones in high quantities, has a relatively high atomic number and is able to efficiently absorb X-Rays. The X-Ray beam that is attenuated by the bones produces a shadow, making them visible on the radiographic image.
It has been recognised that frequent exposure to X-Rays could be harmful, and today special measures are taken to protect the patient and doctor. More than 100 years after Röntgen’s first X-ray experiments, Gerrit Kemerink, a medical physicist at the Maastricht University Medical Center in the Netherlands, discovered an X-ray machine from the 1890’s very similar to Röntgen’s original one and used it to X-ray a hand specimen from his hospital.
