Purpose An optoelectronic surgical navigation system was used to detect small but
measurable translational motion of human hip cadavers in high-range passive motions …

I would like to thank my supervisory team, Dr Colette Ridehalgh, Professor Jeremy Lewis
and Professor Emerita Ann P Moore, for their expertise and continued reassurance …

This paper will present a novel movement invariant approach for overlaying surgical
navigational data on to a live, and moving patient. A pico projector class image projector …

Directional data can be represented as unit vectors. This representation defines a nonlinear
geometry, in which directions can be considered as points on the unit sphere. A consistent …

The hip joint is often described as a ball and socket joint, which has two key implications:
congruent interacting bony joint surfaces and purely rotational relative motion. This model …
