BIMODAL ORGAN PHANTOM AND ASSOCIATED PRODUCTION METHOD

摘要

The general field of the invention is that of phantoms (F) for medical imaging instrumentation, comprising at least a first hydrogel matrix, said matrix containing additives for simulating the optical and acoustic properties of a living organ or tissue. In the phantom according to the invention, the additives are Indian ink or haemoglobin, silica powder and titanium dioxide powder. The phantom may contain a tumour simulator (T) in solid or liquid form. It may also comprise several hydrogel matrices (P, R, S), each matrix containing additives in different concentrations depending on the organ or tissue simulated. The method of producing the phantom includes several freeze-thaw cycles for optimizing the characteristics of the phantom.
