The Motion Modelling and Analysis group (MMAG) is an academic research group based within the School of Biomedical Engineering and Imaging Sciences of King's College London. The group is based at St. Thomas' Hospital in central London.

The primary focus of the MMAG's research is on the imaging, modelling and estimation of repetitive motion. Organ motion due to respiration and the beating of the heart is approximately periodic, so measurements of this motion made from imaging data can be used to construct mathematical models of the periodic motion and its variability. Such models can be applied to update guidance information in image-guided interventions or to correct acquired imaging data for the corrupting effects of motion. The group has an interest in applying such models in a range of applications, but predominantly in the context of image-guided cardiac interventions and PET-MR imaging.

As well as seeing motion as a problem that must be overcome, another research theme of the group is the analysis of motion with the aim of extracting clinically useful biomarkers. Here, work focuses mainly on cardiac cycle motion, in which changes in heart function will manifest themselves as subtle changes in the observed motion of the heart as it beats. By learning distinctive motion signatures it is possible to derive clinically useful information purely by measuring motion patterns.
