<h3>Purpose</h3> In this study, we aimed to test the usability of nitinol, a shape memory metal, in brachytherapy treatment. <h3>Materials and Methods</h3> In order to achieve the aim of the study, we designed a tandem that will be made of polyamide 12 for the straight part (4 and 6 centimeters for both sides) and nitinol for the angled part (4 centimeters). Afterward, we placed the produced tandem into the bolus and measured the dose using different dosimetry methods such as treatment planning system (TPS), Gafchromic film dosimetry, and MOSFET dosimetry. Three different measurements were made with the same irradiation dose for each measurement method, and the average results were recorded. This project was supported by the Scientific and Technological Research Institution of Turkey (TUBITAK) as Project number: 220S572. <h3>Results</h3> The Euclidean distance between source and measuring point was 34.0 millimeters for the Polyamide 12 part, and 32.8 millimeters for the Nitinol part. The calculated irradiation time was 284.9 seconds for the Polyamide 12 part, and 268.2 seconds for the Nitinol part. Dosimetry results are presented in Table 1. Considering the irradiation times and source distances, the calculated difference between nitinol and polyamide 12 was 1.15%. This difference was 1.0%, 1.87%, and 2.08% for TG43, MOSFET, and Gafchromic film dosimetry, respectively. <h3>Conclusion</h3> In this study, we showed that nitinol did not have a negative effect on the dose distribution, and we think that these results should be supported by several studies including other dosimetry measurements.
