Summer undergraduate research presentation

 The two-month summer vacation is almost over, and on Friday 8/21 Seok-Jin Yeo, an undergraduate junior who worked in the Lab, presented his summer research to the GBME colleagues and senior students. Mr. Yeo had successfully calculated the convolution kernels for computing the static magnetic field vectors induced by an object magnetized in an arbitrary direction, and extended gSVC -- generalized susceptibility voxel convolution -- to arbitrary orientations. The results were presented with appropriate levels of details. The students had a pizza lunch after the presentation. Good job Seok-Jin!

RF vector field mapping

 

The multi-orientation B1 mapping method successfully created a first-ever radio-frequency 3D vector magnetic field map in a liquid phantom using MRI. Hard work by Hyeong-Seop Kim to interface a custom-made surface coil with a commercial 3T scanner, unaffected by large orientation changes of the RF coil, paid off to conduct experiments reproducibly. The results are nicely visualized above in a spinning 3D GIF animation created from within Matlab.
