Metro North Health faced a significant challenge. The Australian health service’s clinical imaging was fragmented across more than a dozen departmental systems, creating information silos that hindered a complete patient view.
With 4 billion images and 1.3 petabytes of data, Metro North Health — the largest of 16 hospital and health services in Queensland — needed a scalable, unified solution. Metro North implemented a comprehensive enterprise imaging strategy featuring Hyland Acuo, NilRead and PACSgear to transform its imaging landscape.
The health service now provides almost 18,000 users with secure, real-time, zero-footprint access to a complete patient imaging record from any device — anywhere. This has streamlined clinical workflows and paved the way for advanced AI integration and improved diagnostic capabilities.
With 15 hospitals, 19 campuses, 900 clinics and 26,000 users, tedious processes and imaging silos were significant challenges for UNC Health. With Hyland’s help, the health system simplified its imaging portfolio and generated significant benefits. Explore key learnings, results and benefits from the enterprise-wide initiative.
Metro North Health serves 20% of Queensland’s population across seven hospitals and numerous community facilities. Historically, its clinical imaging was managed in silos.
With at least 12 picture archiving and communication systems (PACS) for specialties such as radiology, cardiology and ophthalmology, clinicians lacked a unified view of a patient’s imaging history.
“I’m not interested in radiology images. I’m interested in the 10,000 images I get every year for burn patients from Torres Strait down to Lismore,” Metro North Chief Digital Health Officer Dr. Jason Brown said.
This fragmentation created significant issues:
“We needed a universal viewer which can be accessed from wherever you are quickly with high quality diagnostic imaging. This is the Netflixing of medical imaging,” Brown said.

Metro North Health embarked on a five-year journey to modernize its imaging infrastructure, partnering with Hyland to implement a solution centered on three core technologies:
Hyland’s vendor neutral archive (VNA) solution became the central repository for all clinical imaging — consolidating data from every specialty. Acuo ingests and manages images from radiology, cardiology, oral health, ophthalmology, digital operating theaters and more.

To solve the access problem, Metro North deployed Hyland’s zero-footprint universal diagnostic viewer. NilRead allows clinicians to securely stream any image from the VNA to any device —desktop, tablet or mobile — without downloading large files.
For nontraditional imaging such as endoscopy and wound care photos, Hyland's image capture workflow engine provides encounter-based workflow generation, ensuring even visible light images are captured and stored with the correct patient demographics.
A critical success factor was tackling the challenge of patient identity. Metro North Health’s imaging solution integrates with the statewide enterprise master patient index (EMPI), which contains records for more than 10 million individuals. This links the 150-plus patient identifiers, creating a “one patient, one imaging” solution and ensuring a complete, accurate record for every individual, Brown said.
The ecosystem is hosted across two data centers with solid-state drives for instantaneous recall and a secure DMZ for authorized external access.

The enterprise imaging solution has delivered transformational outcomes for Metro North Health, empowering clinicians and creating new opportunities for innovation.
More than 17,900 users across 26 sites have anywhere, anytime access to a complete patient imaging record via a single interface.
Imaging from eight major clinical service areas, including statewide cardiology and stroke services, is centralized in the VNA. Radiology now accounts for only a quarter of the total imaging footprint.
Unified data has enabled the integration of AI tools such as Harrison.ai Radiology. In the first three months, the tool helped identify missed incidental lesions on chest X-rays, prioritizing reviews that might have otherwise taken weeks.
Specialty departments such as ophthalmology have connected more than 18 modalities, providing a complete view of a patient’s journey across multiple sites. Digital operating theaters can capture and store video and stills directly in the patient record.
The system manages 4 billion images, 13.5 million studies and 1.3 PB of data with high performance and reliability, growing at 193 TB per year.
“Every image has the potential to deliver future clinical value. Deleting them not only carries hidden costs; it risks losing insights that could support diagnoses, research and improved patient outcomes,” Metro North Health Lead Architect David Anderson said. “By treating images as vital assets, we ensure they remain available — a decision that is both clinically smarter and more cost-effective than discarding them.”
The top goals of healthcare leaders are often at odds with their current reality. Explore interesting insights from HIMSS Market Insights’ annual survey — including why unstructured documents and images remain a significant concern (the numbers tell quite a story).
Metro North’s enterprise imaging platform provides a foundation for continuous innovation. Next, the health service plans to extend the value of its rich data repository.
