Hydrogel fantoms in sono diagnostic
Koňaříková, Anna ; Jugl, Adam (referee) ; Hurčíková, Andrea (advisor)
As part of the practical part of this diploma thesis, an internship took place in the Danish company Dansk Phantom Service, which is engaged in the production of ultrasound phantoms. The purpose was to better understand the ultrasound devices used to characterize these phantoms. Part of the phantom material was provided for measurements on ultrasound devices occuring at the faculty of chemistry of BUT to compare results provided by these devices. The follow-up task was to put into operation a digital oscilloscope, which is used to characterize phantoms, and to create a standart operating procedure. Furthermore, the material of the american company Humimic Medical was characterized and the possibilities of its use for the requirements of the Phillips company were assessed, with the subsequent addition of carbon fibers to the material for the modification of phantom properties. The possibility of preparing a viscous phantom from a mixture of agar, glycerol and water with subsequent charakterization of experimental samples was also investigated. It was found that the values from different ultrasound devices are comparable, differing only in small deviations. Humimic’s Medical material has potencial for specific applications, as does carbon fiber for property modification. A basic mixture of viscous phantom was created that would potentially meet the requirements. However, this basic mixture need to be further modified.
