Improving heating uniformity of pathological tissue specimens inside a domestic microwave oven.

A 3D coupled electromagnetic thermal model was developed using COMSOL 4.0 to predict the electromagnetic field distribution and temperature profile in pathological tissue samples immersed in a reagent inside the oven cavity. The effect of the volume of reagent on the mean heating rate and heating uniformity within the tissue sample was investigated.

Accuracy and reliability of cone-beam computed tomography measurements: Influence of head orientation.

Introduction: The purpose of this research is to determine the accuracy and reliability of measurements obtained from 3-dimensional (3D) cone-beam computed tomography (CBCT) for different head orientations.

Methods: Stainless steel wires were fixed to a dry skull at different places. The skull was scanned by using CBCT in the centered and 5 other positions.

Three dimensional approach for realistic simulation of facial soft tissue response: a pilot study.

Facial attractiveness is ranked as a principal priority among patients seeking orthodontic treatment or combined surgical orthodontic therapy. A successful treatment planning process necessitates an accurate prediction of the postoperative facial profile. In this manuscript, the simulation procedure on a real clinical case using virtual volumetric 3D mesh through different scenarios of orthognathic procedures was done.

Methods for managing 3-dimensional volumes.

The introduction of 3-dimensional (3D) volumetric technology and the massive amount of information that can be obtained from it compels the introduction of new methods and new technology for orthodontic diagnosis and treatment planning. In this article, methods and tools are introduced for managing 3D images of orthodontic patients. These tools enable the creation of a virtual model and automatic localization of landmarks on the 3D volumes.
