alignment accuracy and consistent solder volume transfer is critical for uniform solder reflow. Stencils are usually made of stainless steel. To enhance solder paste release, the walls of the apertures should be as smooth as possible. In addition, rounded corners and a trapezoidal cross-section enhance the release of solder paste from the aperture.

Depending on the number of surgical clips contoured, both matches require a best-fit approach to some extent. While matching to multiple surgical clips

The efficacy of radiotherapy can be compromised by improper placement of shielding blocks, shifting of skin marks relative to internal anatomy, incorrect beam alignment [1], and of course the movement of mobile tumours in the chest. The latter is caused by the patient positioning

Secondly, the location where accurate registration is needed may vary by surgical procedure, e.g., in brain atlas building, good alignment of the ventricle region is sought after, while in image-guided neurosurgery, surgeons are interested in accurate registration of the preoperative (p-) tumor boundary
