Abstract
This study evaluates the possibility of using polyvinyl alcohol (PVAL) composites as phantom material to simulate different densities of breast tissue for mammography based on their elastic properties. Three categories of PVAL gels were prepared by freezing and thawing 10 % water based PVAL (PVAL), ethanol and water based PVAL (PVAL/E) and a blend of PVAL with graphite powder (PVAL/G) solutions to mimic various breast densities. Young’s modulus (YM) of all samples was evaluated by puncture test using the texture analyser. The results recorded ranged from 0.93 to 4.79 kPa for all samples. The results indicate that the PVAL based phantoms examined could be used to simulate fatty and dense breast tissues based on the values of their densities and YM.
