1965. Python-Based
Console for Research/Metrology MRI Scanners
S. Russek, K. Stupic, K. Keenan, S. Ogier, E. Buchanan, E.
Emery
NIST, Boulder, United States
Impact: The open Python console wrapper will allow
easier development of new pulse sequences, assessment of
MRI-measurement biases, better integration of the scanner
with other required hardware, and provide a simple path to
Python-based image processing.

1966. DeepPlanner4Cardio:
an automatic multi-view planning tool for CMR
J. Santos, P. Osório, M. Henningsson, R. Nunes, T. Correia
Instituto Superior Técnico, Universidade de Lisboa, Lisbon, Portugal
Impact: DeepPlanner4Cardio effectively supports CMR
operators by providing an accessible, automated solution to
enable fast and reproducible cardiac view planning,
demonstrating great potential to be applied in a clinical
setting.

1967. In
vivo T1-mapping using Open-MOLLI in GE scanners
A. Gaspar, P. Hughes, J-F Nielsen, N. Stewart, J. Wild, T.
Correia, R. Nunes
Instituto Superior Técnico, Universidade de Lisboa, Lisbon, Portugal
Impact: The open-source myocardial T1 mapping
(Open-MOLLI) was successfully adapted and tested on a GE
Signa 3T PET-MR scanner. The sequence is now ready to be
applied in inter-scanner reproducibility brain studies.
Triggering will be added next for cardiac applications.

1968. SpinSight
– An educational open-source MRI simulator with joint
visualization of pulse sequence, k-space, and MR image
J. Berglund, K. Jain, J. Sousa, K. Hedman, M. Fahlström
Medical Physics, Uppsala University Hospital, Uppsala, Sweden
Impact: An open-source browser-based educational MRI
simulator was developed that jointly visualizes four levels
of the imaging process: acquisition parameters, pulse
sequence, k-space, and the MR image. Low latency enables
students to explore the interaction between these levels in
real time.
