Biography
Research theme: Health
Research program: Medical Physics
Research areas
-
BUA: Broadband Ultrasonic Attenuation for the assessment of Osteoporosis
Although recognised within the 100 Discoveries and Developments in UK Universities that have changed the World and being clinically utilised Worldwide, after 23 years we still do not fully understand its dependence upon density and structure. Professor Langton and his team are studying rapid-prototype replicas of bone samples using resins of varying material properties.
-
MRI: Magnetic Resonance Imaging of Bone Marrow Composition
Bone Marrow has become the ‘forgotten organ’ of bone remodelling research. The hypothesis is that its composition, quantified by magnetic resonance imaging, may predict bone loss and treatment response in osteoporosis, and also the risk of developing a metastasis. A multi-disciplinary scientific and clinical validation programme has recently been initiated.
-
FEXI: Finite Element Analysis of X-ray Images
The aim is to predict the mechanical integrity of the proximal femur utilising a single conventional 2D radiographic image input. Professor Langton has demonstrated that FEXI is superior to conventional bone densitometry for fracture load prediction. He is currently applying the technique to study functional adaptation of human and equine bone.
