For patients

Clear details at every step.

See clinically important details along the patient and clinician journey, right from the first visit. Four key moments you need to get right.

Suspected occult fracture

0.09 mm isotropic resolution helps you see subtle scaphoid and carpal fractures that can be difficult to see on day one.

Scaphoid non-union

Assess trabecular bridging and union with clarity to distinguish a uniting scaphoid from an established non-union before you decide on a treatment path.

Pre-operative planning

Ultra-high-resolution and 3D anatomy supports surgical planning. Walk into the case confidently knowing your plan.

Post-operative insight

Native metal artifact reduction clears the bloom around plates and screws, so the bone–metal interface, thread purchase and alignment are visible.

For surgeons

A dedicated PCCT scanner for the upper extremity.

Designed to be accessible to you and your patients as early in the pathway as possible.

“The scanner provides excellent imaging, particularly of boney anatomy and allows for 3D imaging reconstruction. The resolution between bone and metal implants is particularly good, allowing assessment of bony union as well as early metal failure.”

For Radiologists

Big suite image quality, designed for smaller settings

From urgent care through to community-based clinics.

“The spatial resolution this system provides is excellent for imaging the intricate bony and soft tissue anatomy of the hand and wrist. It gives us high-quality detail that supports our assessment of complex injuries in this region.”

Pedigree

World-class tech for real world clinics.

20+ years of innovation & development. Built from a passion to bring ultra-high resolution (UHR) spectral imaging out of foundational science and into the hands of everyday clinicians. In the same city where Sir Ernest Rutherford conducted early research that later contributed to the discovery of the nucleus, MARS Bioimaging has made the ground-breaking CERN technology inside Medipix3RX photon-counting detectors available for advanced medical imaging across the pathway.
