AFNI at the NIH Scanners
¥ AFNI can take images in ÒrealtimeÓ from an external program and assemble them into 3D+time datasets slice-by-slice
¥ Recently (July 2005), Jerzy Bodurka (FMRIF) has set up the GE Excite-based scanners (3T-1, 1.5 T, NMRF 3 T, and 7 T) to start AFNI automagically when scanning, and send reconstructed images over as soon as they are available:
H For immediate display (images and graphs of time series)
H Plus graphs of estimate subject head movement
¥ Goal is to let you see data as it is acquired, so that if there are any big problems, you can fix them right away
H Sample problem: someone typed in the imaging field-of-view (FOV) size wrong (240 cm instead of 24 cm), and got garbage data, but only realized this too late (after subject had left the scanner and gone home) Ñ DÕoh!
