Pulseq basics

The first lessons of the course: events, blocks and timing, from the two-event experiment that every later lesson extends to a slice-selective gradient echo.

Page	What it establishes
Free induction decay	A pulse and an acquisition window, the limits and rasters they are built against, and the file that is written.
Spin echo	A refocusing pulse and the crusher pair around it, and the shortest echo time the pair admits.
Gradient echo	Slice selection, phase encoding and an echo formed by the readout gradient, and where the echo lands when the prewinder is shortened.
