Key Investigators
- BWH: Scott Hoge
- Utah: Nick Todd, Dennis Parker
Objective
Incorporate improved EPI Nyquist ghost correction techniques and on-line parallel imaging reconstruction modules into the multi-shot EPI sequence used by the HiFU project at Utah.
Approach, Plan
Our plan for the project week is to ...
- modify the multi-shot EPI sequence to include temporal encoding
- integrate fast imaging library calls into ICE image reconstruction chain
Progress
- Temporal encoding of single-shot EPI complete. extending to segmented EPI sequence.
- Functor created to reconstruct acquired data in Siemens ICE framework
- Modified Makefiles to link in NCIGT Fast Imaging Library
Background
- We have a new method for self-referenced EPI ghost correction (EPI-GESTE)
- Goal for the week: implement on Siemens, both pulse sequence changes and on-line recon
- temporal encoding of EPI data acquisition
- application of parallel imaging algorithms
