Knowing the orientation of the head is important in many fields,including medicine. Many methods and measuring systems exist, but usually theyuse different markers or sensors attached to the subjects head for head orientationdetermination. In certain applications these attachments may represent a burden ora distraction to the subject under study which may have an unfavourable impact onthe measurement. We propose a non-contact optical method for head-to-trunkorientation measurement that does not require any attachments to the subjectunder study.

COBISS.SI-ID: 13136667This article presents a new system for 3D foot-shape measurements during walking. It is based on the laser-triangulation, multiple-line-illumination and color-modulation techniques. It consists of a walking stage and four measuring modules that simultaneously acquire the foot shape from the top, bottom and side views. The measuring speed is 30 fps. Custom-developed software makes it possible to analyze the foot's dimensions at an arbitrary cross-section by means of the width, height, girth and section orientation. Six subjects were measured during bare and shod walking, and the bare foot and the outside dimensions of the footwear during the entire stance phase are presented. The relative measurement repeatability of a single subject is 0.5% for bare foot and 1% for shod foot. This means that it is possible to study the differences between various influences on the foot-shape dynamics, such as a bare/shod foot, different loading conditions and the shoe's stiffness condition.

COBISS.SI-ID: 13377563Aesthetically pleasing and symmetrical breasts are the goal of reconstructive breast surgery. Sometimes, however, multiple procedures are needed to improve a reconstructed breast s symmetry and appearance. In order to avoid additionalcorrective procedures, we have developed a new method that uses a reverse engineering technique to produce what we call a new breast replica cast (NBRC). The NBRC is a mould of the contralateral healthy breast, designedaccording to preoperative laser 3D images. During surgery, the mould is used to help shape the new breast. With this method, we are able to achievebreast symmetry in terms of volume, projection, contour, and position on the chest wall more accurately, more quickly, and more safely than before.
