Abstract

This local biological tissue evaluation device includes a phase angle variation amount measurement unit including a sensor having a plurality of electrodes placeable on skin of a subject spaced apart from each other, and configured to inject a current or a voltage between ones of the electrodes in a state in which each of the electrodes is in contact with the skin, to measure a voltage based on a current-injection voltage-measurement pattern when the current is injected, to measure a current based on a voltage-injection current-measurement pattern when the voltage is injected between the electrodes, and to measure a feature amount obtained based on a variation amount of a phase angle for the current-injection voltage-measurement pattern or the voltage-injection current-measurement pattern, a phase angle Jacobian matrix creation unit configured to create a phase angle Jacobian matrix based on the current-injection voltage-measurement pattern or the voltage-injection current-measurement pattern, and an image reconstruction unit configured to image a phase angle distribution inside of a living body of the subject using a phase angle difference and the phase angle Jacobian matrix.
