Quick answer
A digital X-ray is a low-dose imaging test that uses electronic detectors (instead of film) to capture images of bones, lungs and other internal structures in seconds. Compared to film X-ray, it offers up to 50% less radiation, sharper images and fewer retakes. Used for chest, spine, skeletal, abdominal and dental studies.

What is a digital X-ray?
Definition
Digital X-ray (digital radiography, DR)
A digital X-ray uses a small, controlled dose of ionising radiation that passes through the body and is captured by an electronic detector. The image appears on a high-resolution monitor within seconds, can be enhanced without re-exposure, and is stored digitally for future comparison.
How it differs from film X-ray
| Aspect | Conventional film X-ray | Digital X-ray |
|---|
| Image capture | Photographic film | Electronic detector |
| Radiation dose | Higher | Up to 50% lower |
| Image sharpness | Limited by film grain | Higher resolution |
| Retakes | Common for under/over-exposed films | Reduced via on-screen adjustment |
| Archiving | Physical film storage | Secure digital archive |
| Comparison with priors | Manual | Side-by-side on screen |
Digital X-ray studies offered
Chest X-ray
- Common indications: cough, breathlessness, chest pain, fever with respiratory symptoms, suspected tuberculosis.
- Other uses: pre-employment screening, pre-operative evaluation, follow-up of cardiac failure, COPD, pneumonia.
- Views available: postero-anterior (PA), antero-posterior (AP), lateral.
Spine X-rays
- Regions: cervical, dorsal (thoracic), lumbar, lumbosacral.
- Common indications: neck and back pain, post-traumatic injury, suspected disc disease, scoliosis.
- Views available: AP, lateral, oblique, flexion-extension.
Skeletal and extremity X-rays
- Areas covered: shoulder, elbow, wrist, hand, hip, knee, ankle, foot, pelvis, skull.
- Common indications: sports injuries, falls, joint pain, suspected fractures or dislocations.
- Detects: fractures, arthritis, bone tumours, developmental abnormalities.
Abdominal X-ray (KUB / erect / supine)
- Acute abdominal pain evaluation.
- Suspected intestinal obstruction.
- Perforation — looking for free air under the diaphragm.
- Renal calculi (KUB view).
- Confirming the position of feeding tubes, ureteral stents and indwelling devices.
Other specialised views
- Sinus — Water's view
- Caldwell view
- Mastoid views
- Soft-tissue neck
- Nasal bones
- Dental (where indicated)
Why digital X-ray is better for you
- Lower radiation dose — high sensitivity of digital detectors needs less radiation.
- Sharper images, fewer retakes — radiographer adjusts contrast and brightness on screen.
- Instant review — radiologist reads the image moments after acquisition; useful in trauma.
- Easy archiving — digital storage means previous studies are one click away.
- Eco-friendly — no chemical processing, no film waste, no darkroom.
Preparing for a digital X-ray
- No fasting required — eat, drink and take medications normally.
- Wear loose clothing without metal zips, buttons or hooks in the area being imaged.
- Remove jewellery, hairpins, necklaces, watches and metal objects.
- Carry your prescription, previous X-rays and a valid photo ID.
- If pregnant or possibly pregnant, inform our team — many non-essential X-rays can be deferred.
- For chest X-ray, you'll be asked to take a deep breath and hold briefly.
What to expect during the study
- VerificationFront desk confirms your identity, prescription and any pregnancy considerations.
- PositioningRadiographer positions you in front of the detector — sitting, standing or lying down depending on the view.
- ShieldingLead aprons protect areas not being imaged, especially in paediatric and reproductive-age patients.
- ExposureThe actual exposure lasts a fraction of a second; you may be asked to hold your breath for chest views.
- On-screen reviewRadiographer checks image quality immediately to avoid unnecessary retakes.
- Doctor sign-off & reportConsultant radiologist prepares the signed report; delivered on WhatsApp, email and as a printed copy.
Safety and radiation
- A single chest X-ray exposes you to roughly the same radiation as a few days of natural background radiation.
- We strictly follow ALARA — As Low As Reasonably Achievable.
- Lead aprons and gonadal shielding are routine, especially for younger patients.
- Tight collimation exposes only the area being studied.
- Paediatric-specific protocols use further-reduced doses.
- Pregnancy screening is performed before any abdominal, pelvic or lumbar X-ray.
For women of reproductive age: please inform our team about your menstrual cycle and any chance of pregnancy before the X-ray. We follow the "10-day rule" or use alternatives (such as ultrasound or MRI) where applicable.
