BabelBrain: Planning software for Transcranial Ultrasound Stimulation Releases

GitHub_Releases Fix on mechanical index report (0.4.1)

spichardo@www.nitrc.org (Samuel Pichardo) — Tue, 17 Sep 2024 3:30:34 GMT

- **Fix** : Correcting Mechanical Index (MI) report in Step 3. We identified that a wrong mask was used to find the highest value of pressure used to report the MI. This error was only applicable to the MI. The fix now uses the same location as used for the maximal Isppa in the brain. Results from studies using versions of BabelBrain prior to 0.4.1 can retrospectively calculate the correct MI using the formula `MI=SQRT(Selected_Isppa * 1e4 * 2 * 1041 * 1562)/1e6/SQRT(Frequency_MHz)`, where `Sele ... <a href="https://github.com/ProteusMRIgHIFU/BabelBrain/releases/tag/0.4.1">see more</a>

GitHub_Releases Fix on CUDA voxelization (0.4.0-1)

spichardo@www.nitrc.org (Samuel Pichardo) — Wed, 11 Sep 2024 1:44:35 GMT

An update to binary installers is only necessary for Windows. For MacOS, please use R0.4.0.
- **Fix**: Filter for voxelization on CONDA reenabled.

GitHub_Releases UPDATED 0.4.0 - New transducers and ISI-type TUS delivery (0.4.0)

spichardo@www.nitrc.org (Samuel Pichardo) — Mon, 09 Sep 2024 21:05:25 GMT

ERRATA: We had to pull the release we made on Sep 7th, 2023, as a bug escaped our tests. Please accept my apologies.
If you downloaded that version, please delete/uninstall it. This updated version corrected that bug.

-----
- **New**: Information on recommended MRI sequences is available in the repository. The GE settings used at UCalgary are available in PDF, screenshots and tar format. Consult [MRI Sequences](https://proteusmrighifu.github.io/BabelBrain/MRISequences/MRISequences.html) in ... <a href="https://github.com/ProteusMRIgHIFU/BabelBrain/releases/tag/0.4.0">see more</a>

GitHub_Releases Adding advanced options (0.3.5)

spichardo@www.nitrc.org (Samuel Pichardo) — Tue, 09 Jul 2024 19:42:56 GMT

- New: Selection of mapping method for acoustic properties based on CT scanner model, kernel variant and resolution is now available when selecting the CT input in the first dialog. The selected scanner combination will be saved for future sessions. However, default values will be applied when changing the type from real CT, PETRA or ZTE. A reset button to restore default values is also available.
- New: Add advanced options for fine-tuning the processing. In this first iteration, these paramet ... <a href="https://github.com/ProteusMRIgHIFU/BabelBrain/releases/tag/0.3.5">see more</a>

GitHub_Releases Fix for large multipoints simulations (0.3.4-2)

spichardo@www.nitrc.org (Samuel Pichardo) — Thu, 23 May 2024 16:57:13 GMT

* Fix: Correct handling of cases with a large number of sonication points in Step 3 when using low duty cycle.
* Fix: Address hanging in Step 2 when running inside Brainsight with a large list of sonication points

GitHub_Releases Fix on export CSV file for BSonix devices (0.3.4-1)

spichardo@www.nitrc.org (Samuel Pichardo) — Sat, 20 Apr 2024 4:00:52 GMT

* Export CSV for BSonix transducers had a bug preventing the export.

GitHub_Releases Improved speed in Step 2 (0.3.4)

spichardo@www.nitrc.org (Samuel Pichardo) — Sat, 06 Apr 2024 4:43:35 GMT

- Improvement: Significantly faster calculations in Step 2. Improvements to the modeling of acoustic sources in r0.3.2 allowed the elimination of the two-step calculations used in previous versions. Computational cost savings should range between 48% to 40%. A large numerical study was executed to ensure the precision of calculations was not affected.
- Improvement. No more need for Blender. We finally found a native Python CSG library that is robust enough to perform the geometry tasks we hav ... <a href="https://github.com/ProteusMRIgHIFU/BabelBrain/releases/tag/0.3.4">see more</a>
