The eye is a complex structure composed of several interconnected tissues acting together, across the whole globe, to resist deformation due to intraocular pressure (IOP). However, most work in the ocular biomechanics field only examines the response to IOP over smaller regions of the eye. We used high-field MRI to measure IOP induced ocular displacements and deformations over the whole globe. ...
The success of parallel reconstruction methods and their impact on image encoding has sparked a great deal of interest in using the spatial distribution of transmit coils in an analogous fashion. Namely, by breaking down the transmit field into multiple regions each controlled by a separate transmit channel, spatial degrees of freedom are created that allow the spatial information in the array ...
The relevance of cortical grey matter pathology in multiple sclerosis has become increasingly recognised over the past decade. Unfortunately, a large part of cortical lesions remain undetected on MRI using standard field strength. In vivo studies have shown improved detection by using higher magnetic field strengths up to 7 T. So far, a systematic histopathological verification of ultrahigh-fie...
