About the Event
MRI scanners essentially collect samples of the 2D Fourier transform of the magnetization of the object being scanned. For some types of scans the samples can be misaligned, leading to undesirable aliasing artifacts called "Nyquist ghosts" if uncorrected. This talk will show how physics and signal processing can be combined for ghost busting. Joint work with Antonis Matakos and Jon Nielsen, but any bad jokes are entirely the responsibility of the speaker.
