How the Aquilion ONE / INSIGHT Edition CT is making a difference to diagnostics at Royal Bournemouth Hospital

Royal Bournemouth Hospital in the UK was the first in Europe to receive the new Aquilion ONE / INSIGHT Edition CT scanner from Canon Medical Systems UK. Dr. Russell Bull, Consultant Radiologist and Lead CT at the Radiology Department of the Hospital explains how it has already brought about big changes.

The Royal Bournemouth Hospital is a general hospital in Bournemouth, Dorset, UK. It has approximately 600 inpatient beds and 123 day care beds. The hospital provides urgent and emergency care, medical care, surgery, critical care, end-of-life care, outpatient and diagnostic services. The Royal Bournemouth provides services for a population of around 550,000 local people – a number which rises during the summer months due to the attraction of the area as a destination for tourists. The hospital’s radiology department has collaborated with Canon Medical for many years. In addition to the new Aquilion ONE / INSIGHT Edition CT, the department has other Canon Medical CT scanners including an Aquilion ONE / GENESIS Edition and an Aquilion Serve SP.

Dr. Russell Bull was appointed as a consultant Radiologist at Bournemouth, UK, in 2000, initially working as a general cross-sectional radiologist and started a cardiac CT service at Bournemouth in 2004 using a Canon Aquilion 16. For the last 13 years he has worked almost exclusively as a cardiothoracic Radiologist with his time split between cardiac CT and MRI.

According to Dr. Bull, who is responsible for training a large team, The Aquilion ONE / INSIGHT Edition has already delivered many benefits to the 24-strong team of Radiologists and 30 Radiographers.

Dr. Bull commented, “It’s been very easy to train the radiographers on the Aquilion ONE / INSIGHT Edition due to the new efficient INSTINX workflow solution. It guides the Radiographers through the process logically and intuitively.”

Improved resolution

With the Aquilion ONE / INSIGHT Edition’s advanced Deep Learning Reconstruction (DLR), the hospital has benefited from enhanced image quality. Dr. Bull commented, “Generally, the Deep Learning Reconstruction has been very well accepted by our radiologists. The Aquilion ONE / INSIGHT Edition utilises two types of DLR, one of them is Advanced intelligent Clear-IQ Engine (AiCE), which we tend to use in the body, and Precise IQ Engine (PIQE), which we tend to use for the coronary arteries at the moment but is also available for body examinations.”

PIQE is a Deep Learning Reconstruction algorithm that maximises the inherent resolution of a CT to provide Super Resolution 1024 matrix images. PIQE images show sharper anatomical detail for better delineation of small anatomical structures for a more definitive diagnosis.

“The benefit of PIQE 1024 is that it gives us much higher spatial resolution without increasing radiation dose. As it improves spatial resolution, we can image coronary arteries with calcification and stents and we can reduce blooming artefacts. We’ve only had it five weeks, but we are much more confident in our diagnosis because the resolution is much higher,” Dr. Bull added.

High quality at very low dose

Dr. Bull and his team also use the SilverBeam Filter for high-quality images at very low dose. SilverBeam is a filter for Aquilion CT that incorporates silver to selectively optimise the beam energy. It removes low-energy photons from the beam spectrum, which do not contribute to image quality, but do increase dose and scatter. When combined with Canon Medical’s Advanced intelligent Clear IQ Engine (AiCE) technology, this beam-shaping energy filter can harness the power of AI to deliver high image quality and low noise for dedicated applications.

Dr. Bull commented, “We are not just going for low dose – we aim for high image quality at low dose. We are able to do that with SilverBeam. We don’t just use it for lung cancer screening, we use it for standard chest imaging. We also use it for bone imaging because we get much fewer artefacts and the dose is so much lower. If it’s a spine or if we are looking for a hip fracture, we will use SilverBeam.”

Better contrast enhancement

Dr. Bull and his team use 70kVp when they want better contrast enhancement. He commented, “We use 70-kVp to do delayed imaging of the heart to see if there is a blood clot in the left atrial appendage. We use 70-kVp because you get much better contrast enhancement. We also use it when we want to use a very small amount of contrast with patients who have poor kidney function. We have specific CTA protocols, like CTPA, set up in our scanner for these patients.

Smooth transition to new technology

Installing and integrating the new system at the hospital has been seamless, and with the support of Canon Medical, the department has been able to adopt the new technology.  Dr Bull concluded, “We had great support both from Canon Medical Systems UK, Canon Medical Systems Europe and Canon Medical Systems Corporation (Japan). All of these people supporting us has made a huge difference. It really helped us because the new technology is quite different. I think we are still learning, but we learned much faster because of the excellent support.”
