Title:
INFORMATION PROCESSING SYSTEM, PROGRAM, AND INFORMATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/106387
Kind Code:
A1
Abstract:
[Problem] To provide an information processing system which is capable of detecting the position at which a focal excitation wave is produced. [Solution] One aspect of the present invention provides an information processing system. This information processing system is equipped with an acquisition unit, a derivation unit, a detection unit and a generation unit. The acquisition unit acquires a first image sequence which expresses a change in membrane potential in biological tissue. The derivation unit derives a second image sequence which expresses a change in membrane potential by using a circulation variable on the basis of the first image sequence and a first derivation formula. The detection unit detects the position in the biological tissue at which the focal excitation wave is produced on the basis of the second image sequence and a first detection formula. The generation unit generates position information pertaining to the production position.
