Digital X-Ray

X-ray remains the first-line examination in modern radiology.

EastMed Radiology uses the latest digital X-ray technology available, that allows instantly produce crisp-clear images of the requested body region, utilising a much lower radiation dose to patients than conventional units.
The images are available instantly and are then stored in our PACS system (electronic database).

Digital X-Rays

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.

Your X-ray will be performed by a qualified Medical Radiation Technologist.
Once your X-ray is completed it will be reviewed by a Radiologist and forwarded to your referring practitioner via secure HealthLink e-mail or fax.


Wilhelm Rontgen

X-Rays were discovered in 1895 by a German physicist – Wilhelm Röntgen.
There was a lot of speculation in regards to the events that led to the discovery of the X-Rays, as Röntgen had requested for his lab records to be burned when he died. It is believed that in November 1895 he was studying the effects of passing an electrical current through gases at low pressure.

He was using an electron discharge tube, which he had covered with black cardboard to block the distracting glow caused by electrons striking the tube’s glass walls. At one point he noticed that a fluorescent screen, that was more than a meter away from the tube, also started to glow. Röntgen then tried to block the tube with a variety of materials, such as aluminium and copper, but the mysterious rays were still capable of passing through. He labelled them “X”-Rays, for unknown and they were highly energetic electromagnetic radiation, capable of penetrating most solid objects. When Röntgen held a piece of lead in front of the electron discharge tube, it managed to block the rays, but, to his surprise, he saw his own flesh glowing around his bones on the fluorescent screen behind his hand. He then placed photographic film between his hand and the screen and captured the world’s first X-ray image.

Six weeks later, Röntgen published his work and mailed his colleagues a photograph of the bones of his wife’s hand, showing her wedding ring on her fourth finger. In this way an extraordinary discovery had been made: that the internal structures of the body could be made visible without the necessity of surgery.

Dr John Macintyre

By 1896 an X-Ray department had been set up at the Glasgow Royal Infirmary, one of the first radiology departments in the world. The head of the department, Dr John Macintyre, produced a number of remarkable x-rays: the first x-ray of a kidney stone; an x-ray showing a penny in the throat of a child, and an image of a frog’s legs in motion.

In the same year Dr Hall-Edwards became one of the first people to use an x-ray to make a diagnosis – he discovered a needle embedded in a woman’s hand. Shortly after, an American physiologist used X-rays to trace food making its way through the digestive system. Bone, which contains calcium, does not let much radiation through and results in white images on the scan. The lungs, which are filled with air, allow nearly all x-rays to pass through the body resulting in a black image.

The public also embraced the new technology—even carnival barkers touted the wondrous rays that allowed viewing of one’s own skeleton in theatrical show. In the first twenty years following Roentgen’s discovery, X-Rays were used to treat soldiers in the battlefields, finding bone fractures and embedded bullets.


Today x-ray is used to diagnose a wide range of medical conditions:


Cardiovascular Imaging

Computed Tomography


Radiation Therapy


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.

Referring doctors have direct access to our database and can view their patients’ images on their computers. Advanced digital technology allows the medical team to collaborate and, if necessary, compare previous exams with current ones, providing accurate and fast results to the referring medical professional.
Often, X-ray examinations of the joints are combined with Ultrasound to get a full understanding about soft tissue conditions, such as tendons, ligaments and muscles.


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.

X-rays and Gamma rays are electromagnetic radiation of exactly the same nature as light, but of much shorter wavelength. Wavelength of visible light is on the order of 6000 angstroms while the wavelength of X-Rays is in the range of 1 angstrom and that of gamma rays is 0.0001 angstrom.

This very short wavelength is what gives X- and Gamma rays their power to penetrate materials that light cannot. These electromagnetic waves are of a high energy level and can break chemical bonds in materials they penetrate. This makes it a type of ionizing radiation, and therefore harmful to living tissue. The breaking of chemical bonds in the living tissue may result in altered structure or a change in the function of cells. A very high radiation dose over a short amount of time causes radiation sickness, while lower doses can give an increased risk of radiation-induced cancer. In medical imaging this increased cancer risk is generally greatly outweighed by the benefits of the examination.

The beam produced at the tube, contains both low and high energy X-Rays. Low energy (also called soft) X-rays are completely absorbed by the body and do not contribute to the image while increasing the radiation dose. Therefore these rays are filtered out by the aluminium sheet to ensure only the higher energy rays reach the patient and an adequate image is produced, which also contributes to lowering the dose.

Medical Radiography

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.

Organs and tissues such as lungs (filled with air) also show up clearly on the X-Ray because of their very low attenuating properties, creating a shadow that is opposite to the one produced by bones. However, tissues with similar densities and biological composition that are located close to one another are hard to differentiate on the X-Ray.

Generally, radiographs assist in detection of skeletal pathologies as well as some disease processes in soft tissues. A good example would be a common chest X-Ray, which can be used to identify lung diseases such as pneumonia, lung cancer or pulmonary oedema. Abdominal X-Ray can detect bowel obstructions, free air or fluid in the peritoneal space. Gallstones and kidney stones can also often be diagnosed with plain X-Ray imaging. When it comes to visualising soft tissues such as the brain or muscles, general X-Rays have very limited diagnostic value.


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.

He found that to acquire the image, the hand received a radiation dose 1500 times greater than today’s dosage – which explains why many people who were X-rayed or who worked with the original machines suffered from radiation burns and loss of hair. There was also a marked difference in the exposure time required: it took Kemerink 90 minutes to image the hand using the 19th-century machine, compared to 20 milliseconds using modern X-ray machines.
