AbstractAbstract
[en] In Brazil, breast cancer is the most common malignancy among women, accounting for approximately 30% of cases. Adjuvant radiotherapy has a significant impact on the treatment of this disease. Studies point to the benefits of using techniques with respiratory control in the treatment of left breast cancer, with a potential reduction of doses of radiation in the lung and heart. This work presents the design development of a low-cost respiratory control system, to perform treatments using the voluntary deep inspiration technique (DIBH). Tests of linearity, constancy, response time, reproducibility, and accuracy, were performed to validate the proposed system. The linearity and accuracy tests showed R2 values of 0.9999 and standard deviation (SD) ±0.5 mm, respectively. In the constancy test, it was found an average value of 199 mm (nominal value of 200 mm) and SD of ±0.5 mm. The reproducibility test showed an average value of 199 (±0.8) mm (nominal value of 200 mm). System response time was less than 1 second. The results indicate that the system sensitivity is adequate, as the device was able to notice changes in the setup of 1.0 (±0.8) mm. The respiratory management system developed was proven promising to be used in radiotherapy of left breast cancer, using the DIBH approach. The technology is in the patenting phase, and further details cannot be included in this work. (author)
