Specialists in Dental, Oral and Maxillofacial Radiology

The focus at Envision is not only providing high quality images using the latest technology and in truly minimizing the associated radiation, we are also the only practice in WA with three full time oral and maxillofacial radiologists onsite. Clinical Prof Bernard Koong, Dr Tom Huang and Dr Dayea Oh are highly respected and internationally recognised specialist Oral and Maxillofacial Radiologists and we encourage you to view their biographies. The Doctors are always available to clinicians to discuss specific cases, which can substantially contribute positively to diagnosis and outcome for patients. At Envision, we consider this to be an extremely important aspect of radiology.

Instant access to X-rays and scans

Our x-rays and scans can be viewed by the doctor very soon after the patient’s appointment with us. For urgent cases, one of our oral and maxillofacial radiologists can discuss the case immediately over the phone while the clinician is looking at the scan online.

Looking after patients

A key principle at Envision is in caring for patients.

We recognize that these visits can be stressful. All our radiologists, administrative and nursing staff, medical imaging technicians and assistants are dedicated to making all patient visits as comfortable and efficient as possible.

With regards to radiation, our motto is “Ultra low radiation dose levels for every patient, every time”. This is reflected in the technology that we use, the individual protocols prescribed by our radiologists and the knowledge and skills of the technicians carrying out the scans.

Much of the effort in optimizing your results occurs after your patient’s appointment. Our imaging specialists and their technical teams are meticulous in ensuring that all X-rays and scans are processed accurately and interpreted thoroughly.

Our Equipment

Our practice is equipped with state-of-the-art digital equipment including 1.5T MRI, 3T MRI, the revolutionary Force multislice CT with cardiac capability, ultrasound, and the latest in filmless digital reporting and image archiving and distribution to ensure the highest level of diagnostic service for patients.


Panoramic radiographs, more commonly known as OPGs (orthopantomograms), are a special panoramic picture of your jaws. OPGs can be used for a variety of purposes from impacted wisdom teeth, checking development of teeth in children and as general screening as part of your dental check-up. The Lateral Ceph and/or PA Cephs (or cepahlometry examination) are used for checking your facial bones and occlusion, often used in orthodontics. While many radiology practices are digital, all Envision OPG and Ceph machines use only direct capture sensor technology which are capable of producing some of the lowest radiation doses possible.

Ultra low radiation dose levels for every patient, every time

Cone Beam CT is a scan which allows 3D visualisation of the teeth, jaws and face. It is one of the more recent developments in dental imaging. It provides clinicians with much more information about these structures to help with optimal diagnosis and treatment or surgical planning. Envision has two of the leading Cone Beam CT scanners, the iCAT and Sirona Gallileos, at our Wembley and Booragoon rooms. We also have the only i-Cat Cone Beam scanner south of the river at our Booragoon practice. Both these machines are capable of ultra-low dose imaging, comparable to doses delivered in many common dental X-rays. More about Cone Beam
At Envision, the use of a hybrid scanner allows fusion with low-dose CT, allowing assessment of both structural and functional information in one study, greatly increasing accuracy and reducing scan times. More about Nuclear Medicine


Envision has two high quality, modern wide-bore MRI scanners (1.5T & 3T). This ensures better images and a far more comfortable experience for patients than many other scanners in WA. Countless patients have experienced the positive difference we provide - our team of caring MRI technicians puts them at ease, even if they are anxious or have had a bad experience in the past. Most importantly, the excellent image quality allows for accurate diagnosis by our specialist MRI Radiologists. More about MRI


Envision is the only private practice with the new state of the art Siemens CT Somatom Force.  Force mode scanning completes a study in less than a second, at even lower dose, providing better image quality.  In addition, the protocols are personally prescribed by our radiologists to ensure extremely low levels of radiation, while maintaining optimal image quality. What remains the same is the high quality interpretation by specialists who are experts in their field. The low radiation that you receive from our multi-slice CT scans is comparable to many common dental X-ray series. We choose Siemens CT scanners because they include control mechanisms that automatically adjust the radiation dose level to the patient’s anatomy, keeping dose to a minimum.  It is similar to a highly sophisticated camera’s automatic exposure mode and delivers optimum low dose with high quality images.
