A chaotic non-uniform magnetic field of 1000 ppm or more can be suppressed to about 10 ppm by using a single shim coil👀

Assuming manufacturing tolerances in the magnetization and angle of each individual magnet, this will still result in magnetic field inhomogeneities of 1000 ppm or more within the region of interest.👀🧲

This is an animation of the MRI RF pulse optimization process. Ensembles that follow the Bloch equations with different parameters are reconverged to the same point with the same RF pulse⚡

Today, I developed software to optimize the design of excitation pulses and refocusing pulses for NMR and MRI. Because it uses analytical solutions for gradient calculations, it can obtain optimal solutions very quickly🤤

This is Halbach array design software that can optimize a large number of magnets and achieves the latest/highest performance in the world by applying self-consistent calculations. Maybe!🤤

I am currently using a proprietary optimization algorithm to optimize Halbach array magnets for low-field MRI. I am currently planning to perform robust optimization that takes into account manufacturing errors🧲

日本の関西・大阪万博にて東北大学と共同開発のコンパクト低磁場MRIを展示しておりました。こちらは量子スピンセンサを用いた低磁場MRIで、従来の低磁場MRIのSN比の限界を越える可能性の調査での一つのマイルストーンです。

I am an electronic circuit related researcher in a Japanese company, but I build low field MRI as a hobby.I will participate in ENCISMAR2025, so if you see me, please let me know 🙏.

This is the state of development. The circuit board inside the case is removed and its behavior is observed.

This device operates on a very inexpensive and simple circuit, and can be freely modified by users. This device is useful as a first step to understanding NMR devices in detail.

This device works just by connecting USB-C, and pulse programming is possible in the Arduino language, making it extremely easy to use!

By-the-wind sailors, Velella velella. They are cnidarians that travel passively with the wind. If they wash up on the beach, they can’t get back into the water.
