Positron emission tomography (PET) is an excellent medical imaging technique in clinical applications such as brain disease detection and tumor diagnosis. To reflect the level of brain molecular metabolism accurately, larger amounts of radio tracers are sometimes needed, which can be problematic for radiation dose. Improving the quality of the PET image using smaller amounts of radiotracers...
Dynamic mechanical analysis (DMA) is an umbrella term for a variety of rheological experiments in which the response of a sample subjected to an oscillatory force is measured to characterize its dynamic properties. In this work, we present a method for DMA that employs simple magnetic resonance techniques and a small unilateral three magnet array with an extended constant gradient to measure...
Structure functions are employed in many optical scattering experiments for the determination of size distributions in small particles. Recently a similar method for magnetic resonance (MR) has been proposed, Dynamic Magnetic Resonance Scattering (DMRS) [1], which constructs structure functions from MR signal time series data. DMRS is useful in the characterization of sample dynamics, where...
