Gelatine as a hydrogel is a proper material for imitation of biological tissues since human body is mostly formed by water what is a prerequisite for acoustic and mechanical quality. Besides that, this natural biopolymer can be available for low costs. The goal was to find suitable combinations in proportion to gelatine, crosslinker, plasticiser, and preservatives in order to create material for ultrasound brain phantom with optimal time of solidification and similar acoustic property of brain in terminal stage. The emphasis was also put on temperature and microbiological stability requirements. For this purpose, there were arranged set of samples of 5%, 7,5% and 10% of gelatine with different proportion of... |
