Synopsis

A custom built single sided magnetic resonance system, generates an external region of homogeneous B0 = 0.2T field, a sweet spot, from which signal can be detected. The device is capable of relaxometry, diffusion and perfusion measurements and was used to continuously monitor progress of an MCA occlusion in a ovine sheep stroke model. The data from the device was compared to image data acquired on a clinical 3T MRI system.
