理由
This year will be planned to implement the stage (３) Integration of gEIT and clinical trial in Chiba
University Hospital. The research plan are:
(a) Fabrication of gEIT suit for human clinical trial in Chiba University Hospital.(b) Accuracy evaluation of gastric content volume visualization between gEIT and Abdomen Ultrasound.(c) Accuracy evaluation of gastic emptying process between gEIT and 13 C Breath Test.
We already finished the plan (a) Fabrication of gEIT suit for human clinical trial in Chiba University Hospital and (b) Accuracy evaluation of gastric content volume visualization between gEIT and Abdomen Ultrasound. the results is published in [1] K. Sakai, P. N. Darma, P. A. Sejati, R. Wicaksono, H. Hayashi, and M. Takei, “Gastric functional monitoring by gastric electrical impedance tomography (gEIT) suit with dual-step fuzzy clustering,” Sci Rep, vol. 13, no. 1, p. 514, 2023. Corresponding Author.
part of the result will be presented in 23rd international conference of Bio Electrical Impedance Tomography (BIO EIT 2023) in Aachen Germany

| 今後の研究の推進方策 |
Now, we are focussing on (c) Accuracy evaluation of gastic emptying process between gEIT and 13 C Breath Test in collaboration with Chiba University Hospital. Furthermore we will prepare the presentation for 23rd international conference of Bio Electrical Impedance Tomography (BIO EIT 2023) in Aachen Germany from 12th-14th June 2023 and The 4th International Conference and Exhibition on Powder Technology Indonesia in Bali Indonesia from 21-22 August 2023. We will also visit t2i Lab at University of Bergen Norway to talk about research collaboration to combine gastric EIT and Virtual/Augmented Reality. We hope, from the conferences we will obtain meaningful feedback from the experts over the world.We are also preparing JST A-Step proposal in collaboration with Prof. Matsumura and Prof. Hayashi from Chiba University Hospital in order to commercialized the gastric Electrical Impedance Tomography. Furthermore, we are also making a JSPS international proposal in order to propose gastric EIT to solve social problem in indonesia. related with this JSPS international proposal we are trying to collaborate with medical department of gadjah mada university (UGM) Indonesia, we are planning to visit indonesia in August 2023.
