磁石ホルダーの設計をしています👀

By creating your own MRI simulation, you can intuitively understand the process by which the magnetization vector transitions from its initial state to steady-state free precession.🧲

実現可能性を精査しています👀

これめっちゃ楽しいよ！🤤👍

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.👀🧲

明日は磁石のバラつきを仮定した不均一磁場のシミュレーションデータを生成して、それをシムコイルで正確に補正できるかの数値実験をします。

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🤤

まずはこれくらいのを作りたい👀

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!🤤

We are currently developing an application that will allow anyone to design a main magnet for generating B0 in a Halbach array🧲

😎👍

nanoNMRのGUIを作りました👀

ハルバッハ配列の最適化設計の手法を実行しました。非常に良好な最適解を高速に計算できる様になりました。ISMRMで発表したいです🤤（お金がないので出来ませんが

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🧲

Absolutely thrilled to share that I've been awarded a €1.8M 𝐄𝐑𝐂 𝐬𝐭𝐚𝐫𝐭𝐢𝐧𝐠 𝐠𝐫𝐚𝐧𝐭 to develop an AI-driven technology for low-field MRI!

Exciting times ahead!

For students/postdocs - my lab has 𝒐𝒑𝒆𝒏 𝒑𝒐𝒔𝒊𝒕𝒊𝒐𝒏𝒔! 🌟

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。

nanoNMRのPC用のユーザーインターフェースを作り始めました✅
nanoNMRはUSB-Cを接続するだけでTD-NMRの測定ができます。

That's a great idea! I was thinking of publishing it in an easily accessible paper or something!

This is a hobby project so I don't have a specific build plan, but the only specifications I have decided on are a spectrometer that can measure up to 200MHz, a 5W power amplifier, and a temporary 60mT magnet.🦌🧲

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!
