Replace DWI with CS-DSI #8

Closed tsalo closed 2 months ago

tsalo commented 7 months ago

Elements we'd like (@mattcieslak can you expand?):

  1. Magnitude + phase reconstruction
  2. Reverse phase-encoded b=0 scans with magnitude+phase reconstruction enabled as well.
mattcieslak commented 7 months ago

this is a GOOD IDEA

mattcieslak commented 7 months ago

we should use the HASC sequences from Hamsi's paper. If possible, an AP and PA version would be incredible, but we can fall back to just some reverse PE direction b=0s

tsalo commented 7 months ago

The CS-DSI OpenNeuro repo has HASC55 and HASC92. Is the difference just the number of directions? In which case I assume 92 is better than 55.

mattcieslak commented 7 months ago

I think it's only marginally better. What's neat is that there are 2 HASC-55 scans that sample unique coordinates in q-space, so we could do one of them in AP and another in PA, resulting in a total of HASC-110

tsalo commented 7 months ago

Ah, gotcha! So the priority list would be:

  1. AP HASC 55 + PA HASC 55
  2. AP HASC 92 + PA B=0
  3. AP HASC 55 + PA B=0

this sounds good, we may also be able to get a PA scan of just the low-b parts of the first HASC-55 that way we can use the drbuddi multimodal method. I bet we could get that into less than 3 minutes
