OpenVnmrJ is the Open Source variant of the highly successful VnmrJ 4.2 acquisition and processing software
This GPA originated from a collaboration with Jason Stockmann (MGH Harvard). The device can drive up to 4 channels with max 10 A. It is controlled via a single SPI galvanically isolated connection that is also used to read information from the current sensors. Sample code for an Arduino is given that…
The Anser project provides an open-source implementation for electromagnetic tracking (EMT) with particular application to image-guided interventions. This work provides implementation schematics for an EMT system which relies on low-cost acquisition and demodulation techniques using both National…
An MR-Compatible force sensor composed of cheap, off-the shelf components.
A repository that contains many Matlab scripts used to design gradient MR coils.
The spectrometer or software defined radio is capable of producing arbitrary shaped RF-pulses, un-/blanking the RFPA, recording acquired data and controlling a rotating
gradient field. Pulse length, amplitude, readout-length and –delay can be chosen freely.
The RFPA successfully amplied…
An affordable biomedical imaging system that allows to create images based on the electrical properties of tissues.
This modular system provides bias tees for first stage RF preamplifiers, second stage amplification, and programmable attenuation for use in MR scanners and other RF signal applications (at least up to several hundred MHz). Accommodates 32 channels and can be extended by daisy-chaining additional…
Hardware and software designs that enable performing Nuclear Magnetic Resonance experiments using the Earth’s magnetic field.
OCRA stands for Open-source Console for Real-time Acquisition. It is a low-cost, open-source console (hardware controller) for MRI. Conventional MRI consoles may be high cost, closed-source, and inflexible, in that it is not possible to change acquisition parameters once the scan is started. In contrast,…
A 3D Scanner based on structured light and stereo vision.
OpenICE is an initiative to create a community implementation of an Integrated Clinical Environment. The initiative encompasses not only software implementation but also an architecture for a wider clinical ecosystem to enable new avenues of clinical research. OpenICE seeks to integrate an inclusive…
Oscilloscope, Waveform Generator, Spectrum Analyzer, Logic Analyzer and Pattern Generator in one device.
The scanner design is a low-cost resource for demonstrating concepts like magnetic resonance, spatial encoding, and the Fourier transform in an educational setting. A significant part of the system design is open-source.
This project proposes a hybrid system based on a single‐element ultrasound transducer and an MR scanner to help boost temporal resolution in real‐time MRI.
An MRI compatible phantom that simulates the respiration of a human subject in an automated way. A pressure probe is used in order to communicate in continuous time to Matlab the evolution of the respiratory cycle of the subject.
A high‐performance Tx/Rx switch design is presented that supports high peak and high average power applications such as MR imaging, RF heating or thermal MR.
Open Spin Microscopy is an open-source platform to build digital Scanning Light Sheet Microscopes (SPIM/DSLM/OPT).
Customizable high-quality syringe pumps
EEZ H24005 is a power supply that provides features of middle and high range commercial devices.
Open-source brain-computer interface (OpenBCI) is an affordable bio-sensing system that can sample electrical activity of human body such as brain (EEG), skeletal muscle (EMG) and heart (ECG) activity.
echOpen: An open source ultrasound probe that can be connected to a smartphone, tablet or PC
OPENCORE NMR is an open-source toolkit for implementing an NMR spectrometer. This console has the size of a laptop computer, making it easy to transport. The cost of its parts is very low compared to the prize of commercial systems.
Low cost, open source, scalable, current feedback controlled coil driver circuit for matrix B0 shim coils and related applications.
Low cost, open source hardware platform for use in NMR relaxometry experiments. The platform is capable of a wide variety of relaxometry experiments comprising many magnet, coil, and sample combinations.
COSI Measure is an open source multipurpose 3-axis robotic system that allows submillimeter movements for applications such as static/dynamic field mapping, CNC machinery or 3D printing.
