20140360408 | ALKYD RESIN COMPOSITION COMPRISING SILICA - Disclosed is an oxidatively drying alkyd resin composition and a method for preparing said composition. Said composition is obtained by admixing an aqueous silica sol into a substantially 100% alkyd resin being in a liquid state either at ambient temperature or at an elevated temperature. Said silica sol is added in an amount of 0.1-10% by weight calculated as 100% silica on 100% alkyd resin. The use of a said composition is in a further aspect disclosed. | 12-11-2014 |

20100177872 | Method and Device For Online IMRT Verification - A method is provided for monitoring and/or signalling errors of a radiation therapy apparatus during delivery of a radiation treatment to a target, the radiation therapy apparatus being configurable for a given radiation treatment by means of a beam shaping device. The method includes providing a radiation array detector between the beam shaping device and the target, capable of providing a measured detector response of the radiation treatment; determining a predicted detector response for successive times of the radiation treatment; measuring the measured detector response caused by the radiation beams for corresponding successive times of the radiation treatment; performing a comparison between the measured detector response and the corresponding predicted detector response; signalling in a short reaction time, an error when the comparison results in a difference which exceeds a given threshold. The disclosure also relates to a device comprising electronic 2-dimensional detectors, processor device and a main software. | 07-15-2010 |
20100215147 | Method and Device For IMRT Verification - The present invention relates to a method and device for verification of the quality of a radiation beam in conformal radiation therapy, and in particular for IMRT (Intensity Modulated Radiation Therapy) applications. | 08-26-2010 |
