Balanced OVOC is a variant of the FLASH-based
One-Voxel-One-Coil (OVOC) method introduced by Jrgen in
2006. It aims to measure functional responses at a very
high temporal resolution as no or just one spatial
encoding direction is applied. Measurements of
functional responses to visual checkerboard stimulation
at a temporal resolution of 5 ms and one-dimensional
resolution of 1 mm using a small surface coil of 3 cm
are presented. With an echo time of 2.5 ms for bOVOC
signal changes are mostly related to T2 and diffusion
changes.
