MARS Bioimaging Ltd are a Christchurch health tech company breaking new ground in medical imaging. Co-founder and chief medical officer Anthony Butler discusses their vision, and why it makes sense to be based in Ōtautahi Christchurch.
How does MARS Bioimaging technology differ from traditional imaging methods?
We use a technique called spectral photon counting. Basically, we measure each individual photon in an X-ray beam and analyse its energy, wavelength, or colour. This helps us get more detailed information about the tissues we're imaging. Unlike traditional X-rays, which measure the entire beam in aggregate and don’t account for the energy of each photon, our method allows us to understand what specific types of tissues the X-rays pass through.
In what ways is this advancing the field of medical imaging?
Firstly, our technology provides extremely high resolution – about one and a half to twice as good as the best full body CT systems currently available. Second, it allows us to use a lower radiation dose due to the precise photon counting. Thirdly, we can analyse the energy of the X-rays to reduce image artifacts, like those from metal implants, and measure tissue properties, such as calcium concentration.
What are your next steps in terms of technology development and market expansion?
In New Zealand, we’re just weeks away from clinical practice with Reform Radiology in Christchurch. We’ve completed medical physics and radiation safety tests, and we expect to be operational there soon. In the US, we’re partnering with the Hospital for Special Surgery, the world’s largest orthopedic hospital, which is about to start a clinical trial.
What's the company's long-term vision?
We’re focused on providing the highest quality medical images at the point-of-care. Our first scanner is designed specifically for wrist imaging, which is crucial since a wrist injury can really impact your daily life – think about not being able to work or drive. But we’re not stopping there. We’re developing a range of scanners for different uses, like knees and ankles.
We’re also looking into applying our technology for things like stroke and head and neck imaging, and conditions like arthritis and gout. Essentially, we’re creating a series of specialised scanners using the same core technology but tailored for different needs.
