Click here to download Matlab GUI files for running the labs used in MIT 6.S02.
Description of GUIs
The GUIs let students acquire data, view the Fourier transform of the data on-screen, vary basic pulse sequence parameters (such as TE and TR), and save the raw data to a Matlab .mat file.
FID_GUI
The FID GUI lets students acquire a free induction decay and see the Fourier transform (lineshape). The GUI also lets students run a flip angle calibration to find the 90 deg and 180 deg RF pulses amplitudes. The shim can be set either using the "auto shim" tool or by hand using the slider bars or text fields.
SE_PROJ_GUI
The spin echo/projection GUI shows the evolution of the spins in a two-pulse experiment with and without dephase/rephase gradient lobes. Students can see the effect of shimming on the shape of the spin echo. They can also see how applying gradient lobes along each direction creates a 1-D projection of the object instead of a narrow lineshape.

PAST BUG FIXES / REVISIONS
PENDING BUG FIXES / REVISIONS
- create a launchpad with buttons for quickly opening all of the GUIs
- allow user to use "stop" button during auto-shimming
- add gradient echo sequence (FLASH)
- add slice-select pulse sequence
- clean up any remaining timing errors in spin echo and RARE sequences
