  • PyPulseq: Included a sequence template to add sequences with PyPulseq named sequenceTemplate.py
  • PyPulseq: .seq files are saved into the session directory
  • PyPulseq: runBatches method added to mriBlankSeq to run batches with PyPulseq

  • MSE_PyPulseq: Fixed minor bugs in the sequence
  • MSE: Deleted the echo index inherited from RARE that is useless for MSE

October 09, 2024 - v0.6.0 Release

New Features:

  • Sequence template: Added sequence template to create sequence with PyPulseq compatible with MaRGE

Bug Fixes:

  • Console: Fixed issue in the console when switching between main and post-processing window
  • Main Window: Fixed issue in title of main windows when showing the repo version
  • MSE PyPulseq: Fixed some bugs in MSE coded with PyPulseq
  • PulseqReader: Fixed issues in PulseqReader and mriBlankSeq to run .seq files

September 19, 2024 - v0.5.0 Release

New Features:

  • Multi Spin Echo (MSE): A new MSE sequence has been coded in PyPulseq by Prof. Dr. Maxim Zaitsev.
  • Session Management: The session window remains accessible after closing the main GUI, allowing users to create a new session without fully exiting the application.
  • PyPulseq 1.4.2 Compatibility: The GUI is now compatible with pulse sequences coded in PyPulseq 1.4.2. You can download the interpreter from Benjamin Menkuec's GitHub repository, branch pulseq_1.4.
  • Enhanced Console: The console now provides dynamic feedback, including warnings, errors, and statuses, with color-coded indicators for different events.

Bug Fixes:

  • RabiFlop Sequence: Corrected the units for the time axis in the plots.
  • Noise.py: The Larmor frequency is now included in the raw data.
  • Auto-Calibration: Improved the performance of the auto-calibration feature.

August 29, 2024 - v0.4.1 Release

  • FixGain Sequence: Added enhanced error management.
  • ConsoleController: Resolved text management issues.

28/08/2024 - v0.4.0 Release

New Features:

  • FixGain Sequence: Introduced a sequence for adjusting the gain of the RF chain.
  • LarmorPyPulseq Sequence: Added a sequence using PyPulseq to find the Larmor frequency with a spin echo.
  • hw_config.py Updates: Now includes three new parameters:
    • rf_min_gain: Specifies the minimum gain for the receiving RF chain.
    • rf_max_gain: Specifies the maximum gain for the receiving RF chain.
    • rp_max_input_voltage: Sets the maximum voltage for the Red Pitaya's RX channel, with a 225 mV amplitude.

Bugs:

  • Modified the Larmor sequence to address issues with FixGain.
  • Updated the RARE sequence to ensure standalone operation.
