Evaluation of radiation attenuation properties on a various composition of polydimethylsiloxane (PDMS) for fabrication of kidney phantom

Chemical compounds such as polydimethylsiloxane (PDMS) and hydrogen silicone (HS) have been extensively used for fabricating medical phantoms due to its human tissue equivalency. This study aimed evaluate the mass attenuation coefficient, effective atomic number, other radiation properties of various samples verify best material that can be simulate kidney tissue. There are six polymers in total, which denoted S0, S1, S2, S3, S4 S5; these were 20/0/0, 16/4/0, 16/0/4, 12/4/4, 10/4/6 8/4/8, respectively with composition PDMS, HS water. The Photon Shielding Dosimetry (Phy-X/PSD) software (Phy-x.net) estimate properties, results compared theoretical values obtained from XCOM platform. linear PDMS S0 reported highest all samples, is based on 100% without any water HS. S1 sample, only contained 20% HS, was found higher than S2 had but Hence, significantly influences photon energy. Zeff soft different; their respective numbers differ a presence elements Si. reveals modified material, constructed 80% hydrophilic terms total CT number number.
