bOVOC: 200 Hz balanced One-Voxel-One-Coil MREG at 9.4T

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.
