| contents | <p>Background: the aim of this study is to develop synthetic bones from several variations of calcium carbonates and polyester resins for the ANSI chest phantom dosimetry. Material and method: eight samples of synthetic bones from calcium carbonate and polyester resin have been synthesized. The bonding material used was unsaturated polyester resin. The unsaturated polyester resin for each sample was 10 ml and the hardener was 6 drops. The calcium carbonate powder was mixed with unsaturated polyester resin. Degassing was carried out on 8 samples to reduce the bubbles that arise due to the mixing and stirring process. The samples were then put into a mold. The samples were scanned using a siemens somatom definition as CT scanner. Average ct numbers and their homogeneities were measured from their CT images. Result: the results of the eight samples constituted of 0, 10, 20, 30, 40, 50, 60, and 70% calcium carbonate and their CT numbers were +173, +309.1, +321.6, +591, +781.8, +982, +1180, and +1450.3 hus, respectively. However, for 70% calcium was very difficult to be molded. Therefore, the synthetic bones from 10% to 60% calcium carbonate percentages represent human bones from a cartilage (i.e. Hu < +400) to hard bone (i.e. Hu > +1000). For all synthetic bones, the homogeneities are more than 98%. Conclusion: the synthetic bones could be used as human bone in the ANSI chest phantom rather than aluminum sheet. Cartilage is used for young phantom and hard bone is used for adult phantom.
