The IEEE Engineering in Medicine and Biology Magazine of December 1990
contains a number of interesting articles: next to a series of papers
on 3-D Medical Imaging, there is a review of David Winter's Biomechanics
and Motor Control of Human Movement (2nd Edition, Wiley, 277 pp, US $ 50,00,
ISBN 0471-50908-6) and of Children and Exercise XIII (Human Kinetics Pu-
lishers, Champaign, IL 1989, US 45,00, ISBN 0-87233-188-5).

Starting with Gabor T. Herman's "A Survey of 3D Medical Imaging Methodolo-
gies", other papers are concerned with Architectures for Volume Rendering,
3D Image Understanding in Radiology, and Simulation for Craniofacial Surge-
ries based on 3D Image Processing. The final paper, "Future Trends in Three
Dimensional Medical Imaging" comes from authors at the Universit'e de Rennes
in France and at Southeast University, Nanjing, P.R. China.

While the imaging papers are largely concerned with stationary imaging, the
cover graphics show CAD-CAM type models of running humans. Thus, imaging and
movement are getting together, as discussed in the Rennes/Nanjing paper. Yet,
Biomechanics of Human Movement is likely to remain an isoteric activity in
the imaging and radiology field, at least within the foreseeable future.

Furthermore, the IEEE Transactions on Biomedical Engineering of October 1990
contains an interesting article on 3-D tooth movement measurement using four
small magnetic sensors. Within 200 microns, position resolution was better
than 3 microns, and rotational resolution was better than 0.05 degrees.
