Or sequences from different subjects can be aligned for comparative analysis. For example, multiple sequences from the same subject can be aligned and compounded for improved visualisation of anatomy, (Funded by EPSRC grants EP/K030310/1 and EP/K030523/1)Īs well as intensity information, often image sequences are available, and it can be useful to align

The algorithm therefore attempted to find the registration that was most likely to have resulted in the observed ultrasound image. The technique incorporated into the registration a model of how the ultrasound images were formed. 'roadmaps' used for guidance) to intraprocedure ultrasound data. In this work a novel registration scheme was developed for aligning preprocedure segmentations (i.e. Ultrasound/MR Registration Using an Ultrasound Imaging Model King, ' Hierarchical Adaptive Local Affine Registration for Respiratory Motion Estimation from 3-D MRI', Proceedings ISBI, pp1237-1240, 2010.

An example of hierarchical local affine registration. The hierarchical nature of the algorithm, which employed multiple simple registrations rather than a single complex nonlinear registration, resulted in a computationally less complex algorithm than other comparable techniques.

A hierarchical local affine approach to intensity-based registration was developed, in which the hierarchical divisions took into account the image content, in order to ensure that regions of approximately affine motion were formed. In image registration the group has an interest in developing fast and efficient ways of estimating motion from imaging data.
