What is a digital x-ray how does it work?

X-rays are a type of ionising radiation that are produced by a machine to allow images to be taken of the body. These x-rays pass through the body in varying amounts depending on the type of tissue that they interact with. A digital detector receives the x-rays and converts them into an image. Screening or fluoroscopy uses these same x-rays. Instead of a single image being taken, the x-ray can be used for short periods of time to ‘screen’ and obtain real time x-ray images. Doctors and radiographers can then perform procedures using this information.

What involved in having a scan?

You will have to be positioned in front of the x-ray detector – either lying down on a table or standing/sitting. The x-ray unit will then be moved into the correct position and a light will come on to show the area to be imaged. The radiographer will then take the x-ray images. You may need to be changed into a gown for most x-ray procedures. Jewelry near the area to be imaged will need to be removed. Most x-rays procedures only take a few minutes to complete. Screening procedures can be a little more complicated and often involve some form of intervention i.e. injection or administration of contrast etc. Our staff will explain this to you in great detail so you are aware of how the test works. Screening procedures usually take around 30-40mins, but some can be longer.

What equipment do we have?

We have the new Siemens Luminos dRF state-of-the-art x-ray/screening unit. This equipment is very adaptive and flexible to suit all patients. The patient table can be lowered to 48cm from the floor allowing ease of access. The large coverage flat detector ensures we are able to get as much into our image in one shot as possible. This minimizes the need for extra views and reduces patient dose.

What kind of scans can we do?

At Garran Medical Imaging we perform a wide range of x-ray and screening procedures. This can range from chest and abdominal x-rays, spine, extremities, head, orbits, to other more specialised procedures. Screening procedures include barium studies and arthrograms, plus many more.
