Multilayered Tissue Phantoms, Fabrication Methods, and Use

摘要: A method for producing a multilayer tissue phantom involves successively forming at least two layers, each layer formed by depositing viscous flowable material over supporting element or previously of the supported element, selectively redistributing while is solidifying to control thickness distribution layer, and allowing solidify sufficiently apply next layer. The supports in 2 3 directions effectively molds lumen tissue. neighboring layers are different composition chosen provide desired optical properties mechanical phantom. may have selected attenuation backscattering mimic tissues coherence tomography imaging.
