Neurotech Development Kit: an open-source software library designed to enhance accessibility to cutting-edge neurotechnology

Welcome to Neurotech Development Kit

The Neurotech Development Kit (NDK) is an open-source software library designed to enhance accessibility to cutting-edge neurotechnology. Featuring an easy-to-use API and pre-built examples, the NDK provides a seamless starting point for users. Moreover, the NDK offers educational resources, such as interactive simulations and notebook-based tutorials, catering to a diverse audience including researchers, educators, engineers, and trainees. By lowering the barrier of entry for newcomers and accelerating the progress of researchers, the NDK aims to be a versatile and invaluable tool for the neurotech community.

The initial set of target users for the NDK are ultrasound simulation trainees – individuals with backgrounds in technical or neuroscience-related fields who are learning to perform ultrasound simulations. Our goal is to help users familiarize themselves with ultrasound simulation, understand the importance of input parameters, and streamline the process of running and visualizing simulations. In the future, we plan to expand the NDK's features to incorporate additional functionality and modalities, catering to a broader range of users, including ultrasound researchers, product developers, machine learning engineers, and many more.

The initial release of NDK provides support for transcranial functional ultrasound stimulation, with a focus on providing comprehensive documentation, API flexibility, and visualizations. The Neurotech Development Kit is actively developed and we welcome feedback and contributions.

Running

Local installation

neurotechdevkit requires Python >=3.9 and <3.11 to be installed. You can find which Python version you have installed by running python --version in a terminal.

If you don't have Python installed, or you are running an unsupported version, you can download it from python.org. Python environment managers like pyenv, conda, and poetry are all perfectly suitable as well.

You can install the neurotechdevkit package using:

pip install neurotechdevkit

You also have to install stride, it can be done running:

pip install git+https://github.com/trustimaging/stride

devito, a dependency of neurotechdevkit, requires libomp. On MacOS it can be installed with:

brew install libomp

the output of the command above will look like this:

For compilers to find libomp you may need to set:
export LDFLAGS="-L/usr/local/opt/libomp/lib"
export CPPFLAGS="-I/usr/local/opt/libomp/include"

devito requires the directory with libomp headers to be accessible during the runtime compilation, you can make it accessible by exporting a new environment variable CPATH with the path for libomp headers, like so:

export CPATH="/usr/local/opt/libomp/include"

You will also have to set an environment variable that defines what compiler devito will use, like so:

export DEVITO_ARCH=gcc

the supported values for DEVITO_ARCH are: 'custom', 'gnu', 'gcc', 'clang', 'aomp', 'pgcc', 'pgi', 'nvc', 'nvc++', 'nvidia', 'cuda', 'osx', 'intel', 'icpc', 'icc', 'intel-knl', 'knl', 'dpcpp', 'gcc-4.9', 'gcc-5', 'gcc-6', 'gcc-7', 'gcc-8', 'gcc-9', 'gcc-10', 'gcc-11'

Docker

You can run NDK inside a docker container with a couple of steps:

1. Install docker

2. Execute docker run -p 8888:8888 ghcr.io/agencyenterprise/neurotechdevkit:latest

The output of the command above contains the URL of a jupyter notebook server, you can open the URL in your browser or connect to it using your IDE.

Usage

import neurotechdevkit as ndk

scenario = ndk.make('scenario-0-v0')
result = scenario.simulate_steady_state()
result.render_steady_state_amplitudes(show_material_outlines=False)
