MARS Spectral CT: A new paradigm in medical imaging


Owheo G34 - 1:00 pm, Friday 27 May


Spectral Computed Tomography (Spectral CT) is an upcoming medical imaging modality which uses measurements of X-ray colour (energy) to determine an object's composition spread across a 3D volume. The colour information provided by this technology is expected to revolutionise the field of medical imaging by enabling new ways for diagnosing diseases and characterising treatment/drug effectiveness. This is illustrated in preclinical studies that range from diagnosing the early stages of cartilage degeneration to the targeted imaging of cancers.

This talk will provide a broad introduction to Spectral CT with a focus on MARS Spectral CT- a variant based on photon counting technology that is being developed in Christchurch, New Zealand in collaboration between the universities of Canterbury and Otago. The topics covered in this talk will include the differences between conventional and Spectral CT; and the problem of how we determine object composition from Spectral CT data.

Grew up in Napier, in the sunny Hawkes Bay (North Island, New Zealand). Came to Christchurch to study Mathematics and Physics at the same university that my brother was studying structural engineering at. Hobbies include vegetable gardening, growing exotic chillies, video games (playstation), violin, cooking, and I also did a spot of rock-climbing during my student years. I have lived in Christchurch since 2008 and have a partner and two cats.
