1. Imaging in Idiopathic Normal Pressure Hydrocephalus : The value of structured radiological evaluation
Sammanfattning : Background: Idiopathic normal pressure hydrocephalus (iNPH) is a neurological condition where the symptoms include disturbed gait, balance, cognition and continence. The diagnostic guidelines are based on typical symptoms combined with imaging showing enlarged ventricles. LÄS MER
2. Manipulation of Light with Transformation Optics
Sammanfattning : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. LÄS MER
3. Shining Light on Benzothiadiazoles and Indolines : Photophysical Properties and Cancer Cell Imaging
Sammanfattning : Fluorescent molecules, also called fluorophores, play an important role in life sciences. As crucial tools in fluorescence microscopy, they can be used to study biological processes on a cellular level, which is a fundamental aspect of cancer research. LÄS MER
4. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures
Sammanfattning : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. LÄS MER
5. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions
Sammanfattning : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. LÄS MER
