T2 –T2 Exchange in Biofouled Porous Media
Recent two dimensional nuclear magnetic resonance (NMR) techniques access exchange in pore structures through surface relaxation and diffusion based relaxation [1-4]. This research applies these techniques to measure pore changes due to biofilm growth and the impact this growth has on diffusion transport. The porous media used in this study are model beadpacks constructed from borosilicate glas...
متن کاملBias and Unbias Comparison between Economic Statistical Design T2-VSI and T2-FRS Control Charts
The Hotelling's control chart, is the most widely used multivariate procedure for monitoring two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...
متن کاملMR Spin Behavior During RF Pulses: T2 vs. T2' Relaxation
Introduction: We investigate the behavior of the MR magnetization vector during RF pulses in the presence of rapid transverse relaxation. The transverse relaxation is divided into two separate mechanisms: Homogeneously broadened lines which resulting in irreversible T2 amplitude decay, and inhomogeneously broadened lines resulting in dephasing and in principle refocusable T2’. While the two dif...
متن کاملQuantitative OEF Determination by Separate T2 and T2* Mapping
measurement of oxygenation is of great interest, because tumor oxygenation is an indicator of aggressiveness and affinity to metastazation [1]. Moreover, the chance of success of a radiation therapy or chemo therapy depends on the oxygen partial pressure of the tumorous tissue [2]. That is the reason why hypoxia is a large obstacle to tumor therapy [3]. In this study, a model of static dephasin...
متن کاملRobust myocardial T2 and T2* mapping at 3T
PURPOSE Intramyocardial hemorrhage and area at risk are both prognostic markers in acute myocardial infarction (AMI). Myocardial T2 and T2 * mapping have been used to detect such tissue changes at 1.5T but these techniques are challenging at 3.0T due to additional susceptibility variation. We studied T2 and T2 * myocardial mapping techniques at 3.0T on a system employing B1 shimming and compare...
