Delineation of tumor and organs at risk on each phase of 4D CT images is an essential step in adaptive radiotherapy planning. Manual contouring of the large amount of data is time-consuming and impractical. (Semi-) automated methods typically rely on deformable image registration techniques to automatically map the manual contours drawn in one image to all the other phases in order to get compl...

BACKGROUND Contouring of the arms that does not involve skin excision remains a difficult challenge due to the dependent nature and quality of the skin. Although brachioplasty remains effective, it requires a lengthy incision. Radiofrequency-assisted liposuction (RFAL) may improve skin retraction with a satisfactory aesthetic result without skin resection and the resultant scar. The purpose of ...

Background: Surgical treatments for obesity in adolescents were introduced in the 1990s, resulting in individuals undergoing bariatric surgery, and exhibiting weight loss and dys­ morphic body features. This produced a demand for plastic surgery in order to readjust the body contour. The aim of this study was to identify factors associated with morbidity and mortality for these corrective body ...

Model predictive contouring control is a new control scheme based on minimisation of a cost function which reflects the trade-off between the competing objectives of accuracy and traversal time. In this paper, model predictive contouring control is implemented in real time on an X-Y table. The controller automatically adjusts the feed rate to maintain accuracy along the desired path. By varying...

When the method of contouring an object surface by electronic speckle pattern interferometry is based on shifting the illumination beams, the shifted phase of the interference speckle pattern has a new relationship with the depth of the test surface. Therefore the contour interval as well as the fringe sensitivity of this method has new forms. The geometry of such a situation, which differs fro...

In this paper we suggest an approach to a completely automatic contouring the left ventricle (LV). We use the method of signatures to describe the shape of the contour. Analysis of contours performed manually enables us to conclude that the signature of any contour of any patient has the shape of the inverted letter "M". This allows reducing the contouring problem to the problem of signature re...
