Purpose: This study aims for output verification and to validate the dosimetric performance of Varian vertical-type surface applicators using a Farmer-type ion chamber for high-dose-rate (HDR) 192Ir brachytherapy. Materials and Methods: Varian’s vertical-type surface applicators are used at two different dwell positions (d.p) with the source center located at -10 mm and at -15 mm from the centre of first nominal dwell position. Measurements are performed using a Farmer-type ion chamber at 5 mm depth and compared with vendor data and TPS generated values. Relative dosimetry using gafchromic film was performed at 4 mm depth in phantom. The therapeutic area was determined as a full width at 90% dose level. Results: For d.p -15 mm, the measurements showed 9% agreement with vendor data and 5% with TPS calculations. The smallest applicator, SA10, showed poor agreement (percent difference ~14%) compared to vendor data. For the d.p -10 mm, the result reveals the reduced agreement; 13% with vendor data and 6% with TPS calculations. The results from full width measurement at 90% dose level agreed within 2 mm with vendor data and 3 mm with TPS values. The PDD curves showed good agreement for both the vendor data and TPS predictions. Conclusion: This study demonstrates an easy, simple and independent way to verify the output dose measured with Leipzig-style, Varian vertical-type surface applicators. The results validate the performance of these applicators for accurate dose delivery and the treatment of skin cancer, ultimately improving the quality of work and patient care.
