Exhibition at Annual OHBM Meeting in Montreal, Canada

If you are attending this years Human Brain Mapping conference in Montreal, Canada, please visit our booth (#206) and you'll meet BrainVoyager experts answering your questions! We are thrilled to show you several new applications and major updates of existing software, including BrainVoyager 23 with an amazing new volume renderer (see figure below). For the first time, BrainVoyager natively supports Apple Silicon hardware with Metal GPU performance that enables energy-efficient reproducible analyses of large datasets, beautiful real-time renderings and integration of native (arm64) Python as well as accelerated deep learning using TensorFlow. Because of the similarities between M1/M2 iPads and M1/M2 laptop and desktop Macs, desktop-quality BrainVoyager software will also be released for tablets - at our booth we demonstrate, for example, the beta version of BrainViewer for iPad with a touch-driven user interface. Like the recently released Brain Tutor 3D app, BrainViewer not only runs on all major desktop and mobile platforms but it also comes as a WebApp (based on WebAssembly) allowing to launch the app from most web browsers without installing anything. The BrainViewer app not only supports BrainVoyager files but also NIfTI and GIfTI files in a powerful app that can be used to visualise volume and surface datasets with overlaid regions, maps and invoked time courses. The app is so general that it can be used by BrainVoyager users as well as users of other software packages to inspect datasets and to create beautiful publication-ready figures and movies.

We also highlight our latest open source contributions to the software LayNII for state-of-the-art laminar and columnar fMRI analysis. We also present Turbo-BrainVoyager 4.4 that now supports multi-slice DICOM files (used increasingly by SIEMENS) and NIfTI files (used by PHILIPS). TBV 4.4 also comes with a new real-time data simulator that is also included in the Turbo-BrainVoyager 4.4 EDU version. Our EDU products are the ideal tools to teach (e.g. in courses) and (self-)learn how to analyse and visualise structural and functional neuroimaging data from basic to advanced tools including scripting and programming using Python. In our partnership with NIRx (booth #202), we are excited to present the latest version of our real-time fNIRS software Turbo-Satori and a major new version of our fNIRS offline software Satori that now integrates calls into Python tools, for example, in graphically designed data processing workflows.


Brain Tutor 3D Web App

Brain Tutor 3D is now available as a Web App - try it out here! Brain Tutor 3D is the first app that we put on the web, which is made possible by the impressive WebAssembly (Wasm) infrastructure that allows to compile C++ (and other languages) to a cross-platform highly efficient byte code that runs in all major desktop and mobile web browsers. Wasm supports WebGL/OpenGL, which is ideal for BrainVoyager related software that is based on efficient 3D graphics rendering. There are also limitations. As opposed to an installed app, the app is downloaded each time when visiting the page on the web (it is usually kept in memory by the web browser as long as the respective browser page is not closed). While the whole software is packaged in a small wasm file of about 60 MB, it will take a few seconds until the file is downloaded and the web app is running. If one uses an app more than a few times, it may be a better option to download the corresponding desktop or mobile app. Wasm apps are also 32-bit programs (the desktop and mobile versions are 64-bit apps) posing restrictions on handling very large datasets. Wasm apps can be employed easily on the Web, which has the advantage that it runs by clicking on a link instead of downloading and installing different applications compiled for specific operating systems. On the developer side, web employment is easy avoiding creation of platform-specific installers as downloadable packages or as apps for App Stores that come with many extra requirements. Despite avoiding approval from App Stores, WebAssembly apps are secure to use since they run in a sandbox of the browser. This makes it more challenging to use files from the local file system for processing or visualization. This is, however, possible as long as the user explicitly selects (and thereby approves) files from the local system for uploading into the sandbox. This will allow our next web app, Brain Viewer, to process your custom BrainVoyager files but also NIfTI, GIfTI and other files in a powerful web application - stay tuned!
