Claim:
A method for manufacturing a phantom, comprising the steps of: disposing an exudate network with interconnecting at least a first channel and at least a second channel in a container in a manner that the first channel is transversely disposed for an exudate to flow laterally in the container and the top portion of the second channel is longitudinally disposed for the exudate to flow vertically in the container; forming a plurality of solid layers by stacking one on top of another while enabling the first channel to be disposed at the bottommost solid layer and the top of the second channel to be disposed either inside the topmost solid layer or exposed outside the top of the topmost solid layer as the bottom of the second channel is connected to the first channel and extending therefrom upward to the topmost solid layer; and forming a recess in the topmost solid layer in a manner that the bottom of the recess is connected to the second channel.
