Hello OCRA, Tabletop and OSI² community, In this blog post I want to share our SAR Power Monitor µC Interface for the OSI² 2MHz Halbach MRI as part of the A4IM project. The PCB uses the ADL5511 RF-to-RMS IC to convert the applied RF power to a envelope RMS voltage. This voltage gets sampled with…
A4IM OSI² STM32L476RGT compute module
Hello OCRA, Tabletop and OSI² community, In this blog post I want to share my micro controller STM32L476RGT compute module for the OSI² 2MHz Halbach MRI as part of the A4IM project. The module will be used for the open-source SAR hardware monitor to sample the applied RF power, calculate the running averages and switch…
A4IM OSI² TR-Switch
Hello OCRA, Tabletop and OSI² community, In this blog post I want to share my Transmit-Receive (TR) switch design for the OSI² 2MHz Halbach MRI as part of the A4IM project. The A4IM OSI² TR-Switch is based on my OCRA Tabletop MRI System TR-Switch. The schematic is basically the same and only a few components…
