A status report is presented about the Nanoplasmonic Laser Induced Fusion Experiment (NAPLIFE). The goal to investigate and verify plasmonically enhanced phenomena on surfaces of nanoantennas embedded in a polymer target at laser intensities up few times 1016 W/cm2 pulse durations 40–120 fs. first results crater formation for Au-doped targets are shown, SERS signals typical CD2 ND bound vibrati...

PURPOSE To compare dose reconstruction accuracy with different oblique beam angles when 2d detector arrays are used for small field IMRT QA. METHODS 2D detector arrays are convenient to use but their low resolution limits the number of sampling points inside small radiation fields. In this study, we demonstrate that with oblique beam incidence, more points can be measured and 3D dose volume c...

Abstract In computed tomography (CT) reconstruction, ring artifacts emerge from incorrectly normalized or defective detector elements. Correction algorithms often introduce blur do not correctly accommodate the behaviour of those artifacts. Normalization errors stem noise in images during normalization process and are always present to some degree. We propose a method for correcting elements si...

Larynx is part of the upper respiratory tract composed of cartilaginous skeleton, muscles and mucus lining inside. This structure keeps larynx open for air passage and is one of the important factors in producing voice. A good knowledge of larynx dimensions is neccessary to obtain better results in the treatment of laryngeal disorders. The size of larynx and its dimensions are subject to sex, r...
