Research
Anthony Butler's research is at the interface of clinical medicine and the technical sciences of physics and computing. His current focus is the development of MARS imaging and its translation from high energy physics to clinical medicine. The MARS technique provides 3D colour (spectral) X-ray images of biological tissue. These images provide significantly more clinical information than those modalities currently used in hospitals and laboratories. This enables researchers and clinicians to study diseases in new ways.
Currently he and his collaborators are applying MARS to problems in heart disease, cancer, drug development, and bone health. MARS technology research spans particle detector development, design of imaging equipment, medical mathematics, and data visualisation. In addition, his other interests include the using mobile computing and virtual reality within hospitals.
