Plotting

Figures of a sequence, of its ADC sampling locations in k-space and of its RF pulses. Each figure is a function of the object it draws. plot() and paper_plot() are also pypulseqpp.Sequence methods, for scripts written against upstream PyPulseq; the other figures are functions only.

Sequence views

plot() requires SeqEyes, an optional viewer installed with pip install 'pypulseqpp[plot]'.

Object	Input	Returns	Purpose
plot	Sequence, arguments of Sequence.plot	SeqEyes viewer process	Interactive view of the sequence.
paper_plot	Sequence, arguments of Sequence.paper_plot	Matplotlib Axes	Publication diagram of one repetition over the others.

Colormaps

The colormaps the figures on this page are drawn with, for figures drawn beside them.

Object	Input	Returns	Purpose
SAMPLING	Normalised value in [0, 1]	RGBA colour	Acquisition order, first to last.
MAGNITUDE	Normalised value in [0, 1]	RGBA colour, transparent at zero	Magnitude from zero.
SIGNED	Normalised value in [0, 1]	RGBA colour, transparent at 0.5	Signed quantity about zero.

k-space and RF profiles

Object	Input	Returns	Purpose
plot_kspace	Sequence, range, projection plane, color_by	Matplotlib Figure	ADC sampling locations in k-space (1/m), after each block’s rotation.
plot_rf	Sequence, module or RF event; pulse; profile axis or plane	Matplotlib Figure	RF envelope beside its magnetisation profile.
