A conventional birdcage head coil at 7T is not well suited for certain applications such as motion control. We propose an original coil based on a birdcage with a wide lateral aperture that provides access to the object under examination. We show that a sufficiently homogeneous magnetic field distribution can be obtained by optimizing the current distribution of such an “Opencage”. That coil was optimized using a full wave simulation and tested experimentally. The performance of an Opencage coil was compared to a commercial birdcage coil. Eventually, the Opencage coil is shown as a tradeoff between field homogeneity and access.
