- Tracing vocal fold vibrations using level set segmentation method
Tailong Shi, Hyun June Kim, Thomas Murry, Peak Woo and Yuling Yan
Article first published online: 17 APR 2015 | DOI: 10.1002/cnm.2715
We introduce a new approach that combines the use of level set segmentation method and motion cue to segment videokymogram (VKG) images and exact vocal fold displacements for further analysis. This approach is applied to VKG-form image, obtained from a sequence of laryngeal images captured by the HSDI. The performance of the proposed approach is evaluated using clinical datasets representing both normal and pathological voice conditions.
- Focal cartilage defect compromises fluid-pressure dependent load support in the knee joint
Yaghoub Dabiri and LePing Li
Article first published online: 14 APR 2015 | DOI: 10.1002/cnm.2713
A small cartilage defect could cause 25% reduction in load support in the knee associated with compromised fluid pressurization in the tissue. A defect also increased shear strains at the cartilage-bone interface. Load bearing characteristics of the joint deteriorated with the defect depth. The altered mechanics of the knee were also influenced by the sites of defects and the contact conditions in the defect regions. The fluid pressure load support in a defect joint was highlighted.
- Finite element evaluation of the effect of fingertip geometry on contact pressure during flat contact
Gregor Harih and Mitsunori Tada
Article first published online: 10 APR 2015 | DOI: 10.1002/cnm.2712
The study utilises the finite element method to evaluate the effect of physiological factors on the variations of pressure discomfort and pressure pain threshold in the hand between different subjects while grasping a flat surface. Numerical results show that underlying anatomical structure and geometry, especially of the bone, significantly affect peak contact pressure and contact pressure distribution, which explains the differences in pressure discomfort and pressure pain threshold existing from subject to subject.
