Brainsight 2.5.3 is released for all users

We are happy to announce the release of Brainsight 2.5.3.

Before proceeding with this update, please read the following important information.

Minimum requirements:

  • macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <https://support.apple.com/macos/upgrade>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7 (Monterey), 13.6 (Ventura), and 14.3 (Sonoma).
  • Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.2:

  • Brainsight can now simulate the acoustic effect of transcranial focused ultrasound (fUS) at a target location. It does this by interacting with BabelBrain, a third party software that must be installed separately. The Targets window now allows invoking BabelBrain, wherein simulation parameters can be set. The resulting simulation appears overlaid in 2D and 3D images, and can be customized from the Inspector window.
  • When writing to our .txt file formats, we now use slightly different coordinate system names for NIfTI files, which may require updating code that reads these files. The coordinate system name now includes whether it’s from the file’s sform or qform. So, for example, where we used to use a string like “NIfTI:Scanner” we now use “NIfTI:Q:Scanner”. For this reason, exported .txt files increased from version 13 to 14, and .txt files created by streaming increased from version 6 to 7.
  • Improved performance when creating hundreds of samples. There should be noticeably less latency between the trigger that creates a sample and its appearance in the application.
  • Substantially improved accuracy of Vet Robot subject registration, thus improving accuracy results overall.
  • Fixed a bug, introduced only in 2.5.2, where selecting two or more samples was not showing the average waveform for EEG and NIRS views (but was for EMG views).
  • Fixed a bug where EMG waveform views sometimes did not show the visual indication (crosshatching) of when a waveform has exceeded the EMG pod device’s maximum range of 2.25 mV.
  • Fixed a bug in EMG views where the line indicating the EMG latency would sometimes not redraw after the time range was changed (with the green vertical bars).
  • Fixed a bug where electrodes could still be clicked in 3D views, even when all electrodes were hidden.
  • Fixed miscellaneous bugs.

Download:

  • Brainsight 2.5.3 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
  • You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.
  • You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.

Feedback:

  • Please report any and all bugs, feedback, suggestions, etc. to <support@rogue-research.com> or by phone at +1-866-984-3888 (Canada & USA) or +1-514-284-3888.

Brainsight 2.5.2 is released for all users

We are happy to announce the release of Brainsight 2.5.2.

Before proceeding with this update, please read the following important information.

Minimum requirements:

  • macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <https://support.apple.com/macos/upgrade>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.10 (Big Sur), 12.7 (Monterey), 13.6 (Ventura), and 14.0 (Sonoma).
  • Mac OS X 10.12 (Sierra) and earlier are unsupported.

Changes since version 2.5.1:

  • Added calculation and display of EMG latency using the SHTE algorithm (by Šoda, Vidaković, Lorincz, Jerković, and Vujović). The Perform and Review windows now have a new optional table column that can show the latency for each sample. In addition, waveform views now draw a vertical line at the latency time. This line can be dragged to adjust the automatically computed value if it seems incorrect. Latency can also be streamed to a .txt file from the Perform window, and exported to a .txt file from the Review window.
  • Each surface-type reconstruction can now be configured to participate in overlay blending or not. If the option is off, overlays will never be blended on that surface. If the option is on, overlays will be blended atop that surface, provided the overlay is enabled in the Inspector window (as usual). This option is off by default.
  • A tool calibration’s 4×4 matrix can now be exported to a MINC .xfm text file.
  • The Vet Robot can now be moved relative to the currently used tool.
  • The Session Polaris window now allows selecting the Polaris, and also has a button in bring up the Polaris Configuration window.
  • More windows now have the option of showing the crosshair’s numerical coordinates (at the bottom right).
  • Fixed a bug where some projects with corrupt NIRS data would fail to load.
  • Fixed a longstanding bug where the brightness/contrast slider did not work in the Curvilinear From Overlay and Surface From Overlay windows when an overlay was used as the source of the reconstruction.
  • Fixed a bug where Brainsight would not automatically connect to a Polaris, even if it was detected.
  • Fixed a bug where some image views would stop drawing after Brainsight was running in the background.
  • Fixed a crash creating motor maps on old Macs with Nvidia GPUs.
  • Improved performance creating motor maps on Macs with Apple Silicon processors.
  • Fixed several crashes that could occur when opening corrupt files of various formats.
  • Fixed miscellaneous bugs.

Download:

  • Brainsight 2.5.2 can be downloaded from our website here: <https://www.rogue-research.com/downloads>

Brainsight 2.5 is released for all users

We are happy to announce the release of Brainsight 2.5.

Before proceeding with this update, please read the following important information.

Minimum requirements:

  • macOS 10.13 High Sierra is now the minimum requirement, increased from macOS 10.11 El Capitan in Brainsight 2.4. For a free update, visit <https://support.apple.com/macos/upgrade>. Contact us if you need to upgrade your Mac hardware.
  • This version of Brainsight was tested against macOS 10.13.6 (High Sierra), 10.14.6 (Mojave), 10.15.7 (Catalina), 11.7.4 (Big Sur), 12.6.3 (Monterey), and 13.2 (Ventura).
  • Mac OS X 10.12 (Sierra) and earlier are unsupported.

Important Compatibility Note:

  • The project file format has changed. Brainsight 2.5 can open documents created by older versions of Brainsight, but older versions of Brainsight cannot open documents created by Brainsight 2.5.

Changes since version 2.4.11:

  • Brainsight can now simulate the induced electric field due to a TMS stimulation at a target location. It does this by interacting with SimNIBS, a third party software that must also be installed. The Targets window now allows associating a TMS coil model and stimulation strength with each target. The resulting simulation appears overlaid in 2D and 3D images, and can be customized from the Inspector window.
  • 3D reconstructions (like the skin reconstruction) are now coloured by blending any enabled overlays atop the reconstruction’s own colour.
  • Overlays now support time series data (though only from NIfTI and MINC2 files, not other formats). The Overlays window and Inspector window now have a new slider to choose the time offset.
  • Very large datasets (with more than 2^31 voxels) can now be used.
  • Made various accuracy improvements to Vet Robot stereo calibration and subject registration, resulting in more accurate targeting during surgery.
  • In the Session Perform window, creating new samples is now disallowed if the relevant Polaris tools are not visible.
  • In the Session Perform window, the ‘stream to file’ feature now includes EMG waveform data and the coordinate system for selected targets and created samples.
  • In the Session Perform window, the ‘Sample Now’ button is now disabled if the required tools are not visible to the Polaris camera.
  • When working with the Axilum robot/cobot, a new ‘scalp offset’ distance can be specified to keep the TMS coil a few millimetres above the scalp to account for the thickness of an EEG cap for example.
  • EMG waveform views now visually indicate when a waveform has exceeded the EMG pod device’s maximum range of 2.25 mV.
  • Added support for the Cornell University (Johnson, Philippa J; Barry, Erica F) canine atlas.
  • Fixed various bugs with some DICOM datasets, where images would appear split in half, have gaps, or have missing slices.
  • Fixed a longstanding bug where reconstructions based on ROIs would claim that re-computation was necessary, even though the ROI hadn’t changed. (This was partly fixed in 2.4, but still occurred for re-opened projects.)
  • ROIs can now be created by importing from a medical image file (DICOM, NIfTI, MINC, etc.).
  • Fixed a bug in the ROI window where the pencil and eraser tools would not work correctly at the edge of view, especially when moving the mouse quickly.
  • NIRS waveforms can be imported from a .nirs file, thus allowing importing data from other manufacturers’ NIRS devices.
  • Fixed a bug (introduced in Brainsight 2.4.11) where the SD.SrcPos and SD.SrcPos3D fields in exported .nirs files were swapped.
  • Fixed a bug (introduced in Brainsight 2.4.5) where the SD.SrcPos field in exported .nirs files were in decimetres instead of centimetres. (The SD.SrcPos3D field was exported correctly in millimetres though.)
  • Assembly Lists and Cap Layouts can now be created by importing from a .nirs file.
  • Calibrating a TMS coil or other tool now allows for the tool tracker and calibration tracker to move together (relative to the camera), instead of failing if either tool moved relative to the camera.
  • Polaris tool visibility status now uses a larger coloured area, making it more visible from father away.
  • The enabled/disabled state of Polaris tools in the Polaris Configuration window are now remembered across quit/relaunch.
  • Landmarks, targets, electrodes, and samples can now be clicked in 3D image views to select the corresponding item in the related table view.
  • Targets can now be exported to a text file from the Targets window (export was previously possible, but only from the Session Review window).
  • In the Targets window, if a reconstruction is chosen in the ‘optimize traj. to’ popup menu, clicking in 2D views no longer reorients crosshairs.
  • Exporting curvilinear reconstructions in the PLY format now includes the voxel values in greyscale, whereas previously no colour was exported, only the shape.
  • When exporting reconstructions as STL, VTK, and PLY you can now choose between the ASCII and binary variants of these file formats.
  • When importing a reconstruction from file, the object can now be placed relative to a chosen target (useful for placing chambers for example).
  • The crosshairs in 2D image views now have a small gap in the middle so as not to obscure the very thing being targeted.
  • Wherever 4×4 matrices can be imported from a file, a new file format is now supported namely plain text files with 16 numbers within.
  • The crosshairs offset slider now allows a large range.
  • When opening a project file, if there are referenced external files (datasets, CAD files) that can’t be found, the dialog that asks to find them now (by default) disables files with different names, thus making it much easier to find the correct file.
  • A new preference allows changing the colours of the bullseye views, especially useful for colour blind users.
  • A new preference allows changing the font size of the bullseye views.
  • A new preference allows specifying default EMG baseline and trial durations that will be used when creating new sessions.
  • Native support for Apple Silicon processors.
  • Improved support for macOS 11 Big Sur, macOS 12 Monterey, and macOS 13 Ventura.
  • Various performance improvements:
    • Exporting DXF files is now much faster, especially for large reconstructions.
    • Updating an atlas space template overlay is now much faster.
    • Reorienting the anatomical dataset is now much faster.
    • Creating curvilinear reconstructions is now much faster.
    • Creating skin and other surface reconstructions is faster.
  • Fixed miscellaneous bugs.

Download:

  • Brainsight 2.5 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
  • You might also need to download the latest “Support Files Human” and/or “Support Files Vet” if you have an older version. Brainsight will warn at launch if that’s the case.
  • You’ll need your serial number, which you can get from Brainsight itself from the Brainsight menu > ‘Enter/View Serial Number’.

Important Compatibility Note:

  • If you are already using the Brainsight 2.5 beta, don’t install this version. A new 2.5 beta is coming out shortly.

Changes since version 2.4.8:

  • There is a new checkbox in the Session > IOBox step to indicate if you want to save or discard the live/full EMG waveform. It’s usually not necessary to save it, because samples contain a copy of the EMG waveform just before and after the TMS pulse, and as it can grow very large it slows performance, especially saving and opening project files.
  • Resuming a session no longer overwrites any existing live/full EMG waveform, instead it now appends new data to the end.
  • Fixed a bug where the EMG pod was sometimes not detected between closing and resuming sessions or when disconnecting and reconnecting its USB cable.
  • Fixed a bug where exporting .nirs files would fail if the project did not contain any NIRS Aux data.
  • When stopping an Axilum session, we now perform an extra movement to make sure the robot arm stays in the working space.
  • Fixed miscellaneous bugs.

Download:

  • Brainsight 2.4.9 can be downloaded from our website here: <https://www.rogue-research.com/downloads>
