The aim of the present study was to determine the frequency of atlanto-axial rotatory subluxations (AARS) in multi detector computed tomography (MDCT) performed on human corpses for forensic purposes and to investigate whether these are a physiological postmortem finding or indicate a trauma to the neck region. 80 forensic cases examined with MDCT from November 2003 to March 2007 were included ...

In this study, a novel method is proposed to represent the three dimensional angular position of the body segment in space with least singularity adopting the new definition of the axial rotation. Firstly, the orientation of the axis of the body segment is defined by the geographical coordinate system (ISO 31-11). Secondly, the axial rotation of the body segment is defined by the rotation offse...

The use of the constant-deviation prism for producing monochromatic light introduces the problem of image shifts that result from rotating the prism when changing from one spectral line to another. The magnitudes of both the lateral and the axial components of this shift, for a given rotation of the prism, depend upon the position of the axis about which the prism rotates. A position for the ax...
