Thanks for the correction and sorry for the mistake!!
I "miswrote" this morning.
Actually, i meant echo spacing when i wrote TE. The echo spacing is of
course not 30ms but much shorter, 0.53ms.
To summarise:
I have an EPI sequence [Siemens MAGNETOM Trio (TIM System)] with
following unwarping-relevant parameters:
- echo spacing = .53ms
- number of in plane lines in the reconstructed epi image = 64
- acceleration factor = 2
- number of in plane reference lines = 24
My questions:
What do I have to enter as the echo spacing for b0 field unwarping with
feat/fugue?
(a) .53ms/2 (echo_spacing*#lines_in_images / acceleration factor)
(b) .53*64/(32+24) (echo_spacing*#lines_in_images/(#lines_in_images +
#reference_lines))
(c) something else ...
