Hello OCRA and Tabletop community, in this blog I will share the actual development status of the OCRA Tabletop MRI System hardware and the OCRA/Relax2.0 software. The 2024 OCRA Tabletop MRI System hardware development was mainly driven by the AgriPETMRI project at the Research Campus STIMULATE, were I work as leader for the MR System…
Gradient Coils for the OCRA Tabletop MRI System
Hello OCRA and Tabletop community, In this blog post I want to share our gradient coil design for the OCRA Tabletop MRI System. Gradients fields are necessary to encode spatial information to the spin signal. As the origin of the spin signal is the homogeneous magnetic field (B0) it is possible to variate this field…
Relax2.0, a graphical user interface for OCRA
Hello OCRA and Tabletop community, In this blog post, I will share the news about the first GitHub publication of my Relax2.0 graphical user interface (GUI) for OCRA. Relax2.0 is based on the original OCRA server for the Red Pitaya by Thomas Witzel and the PyQt GUI Relax by David Schote. Relax2.0 can be downloaded…
RF-Coil for the OCRA Tabletop MRI system
Hello OCRA and Tabletop community, In this short blog I will share my radiofrequency (RF) -coil design for our OCRA Tabletop MRI system. The coil is a simple solenoid design. To make it sensitive to the measurement (Larmor) frequency it is built as an electrical resonator with parallel capacitance. To match its impedance to a…
