TomoEDGE is an advanced delivery form of tomotherapy which uses a dynamic secondary collimator. This plan comparison study describes the new features, their clinical applicability, and their effect on plan quality and treatment speed. For the first 45 patients worldwide that were scheduled for a treatment with TomoEdge, at least two plans were created: one with the previous "standard"mode with ...

Background: The lack of lateral electronic disequilibrium (LED) becomes a main problem in small field. This factor affects the dose in target volume cannot predict correctly. In addition, utilization of high-energy linear accelerator (10 MV) can emit some unwanted particles (electron contamination). Therefore, the aim of this study was to characterize head linear accelerator (linac) Varian Clin...

Introduction: Penumbra is an important property of the radiation beam to obtain a suitable margin surrounding the target volume. Therefore, the precise penumbra width determination in stereotactic radiotherapy is necessary for treatment planning. This study aimed to compare the obtained results of penumbra width by in-house and standard circul...

STATEMENT OF PROBLEM In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood. PURPOSE The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions...

The goal of the study was to analyse statistically the survey of measurable parameters distinguishing human facial skeleton as well to construct mathematical model describing foetal facial skeleton selected features. The material consisted of 112 foetuses (44 females – 39.29% and 76 males – 60.71%) in the CRL: 83-245 mm, aged 4-7 months of foetal life. The whole of the examined material origina...

Gender determination of Muscovy duck as early possible is essential for the efficiency and effectiveness production. This study aimed to determine morphometric differences in prepubertal male female (Cairina moschata) predictors gender. used a split-plot design, with observed variables cranium length, width height, mandibular rostrum length width. total 80 samples heads consisting 40 heads, ten...

Logvinenko [Perception 31, 201 (2002)] asserts that Adelson's wall-of-blocks illusion [Science 262, 2042 (1993)], where identical gray-cube surface tops appear to differ in brightness, arises when the surfaces surrounding the cube tops are shadow compatible, creating a concomitant illusion of transparency. We replicated Logvinenko's main findings in the chromatic domain across three experiments...
