recommendations! Published in 2020 at "Medical physics"

DOI: 10.1002/mp.14340

Abstract: PURPOSE To achieve a superior balance between dosimetry and the delivery efficiency of intensity modulated proton therapy (IMPT) using as few beams as possible in a single fraction, we optimally vary beams in different fractions.… read more here.

DOI: 10.1002/mp.16009

Abstract: PURPOSE The combined use of Bragg peak and shoot-through beams has previously been shown to increase the normal tissue volume receiving FLASH dose rates while maintaining dose conformality compared to conventional IMPT methods. However, the… read more here.

DOI: 10.1002/mp.17798

Abstract: Spatiotemporal fractionation schemes aim at partial hypofractionation in the tumor along with more uniform fractionation in the normal tissue. This is achieved by delivering distinct dose distributions in different fractions, where each fraction contributes with… read more here.

DOI: 10.1016/j.compstruct.2017.02.061

Abstract: Abstract This study thoroughly investigated the flexural behaviour of phenolic cored sandwich beams with glass fibre composite skins in the horizontal and vertical positions. The beams have a shear span-to-depth ratio (a/d) varying between 0.5… read more here.
