Abstract
An optical phantom of a living body includes a multiplicity of phantom layers shaped to the contours of a target part of a living body. A space portion is provided at a prescribed location inside the phantom. Inlet and outlet conduits enable liquid phantom to be supplied to the space portion and removed therefrom. This arrangement enables the space portion to be used to simulate dynamic change of physiological states, and for such changes to be measured optically.
