Tensor-Based Cortical Surface Morphometry via Weighted Spherical Harmonic Representation
Abstract--We present a new tensor-based morphometric framework that quantifies cortical shape variations using a local area element. The local area element is computed from the Rie...

Characterization of Flexible RF Microcoil Dedicated to Surface Mri
In Magnetic Resonance Imaging (MRI), to achieve sufficient Signal to Noise Ratio (SNR), the electrical performance of the RF coil is critical. We developed a device (microcoil) ba...
