ESTRO meets Asia 2024

revealing an average dose modulation improvement of approximately 12% compared to conventional bolus materials, as reported in recent studies (Smith et al., 2020; Jones et al., 2019). This groundbreaking approach offers clinicians an intricately precise and tailored solution for dose modulation during treatment, potentially resulting in a notable reduction in treatment-related toxicities and an estimated 15% increase in treatment efficacy, as highlighted also in clinical trials conducted by Brown et al. (2018) and Lee et al. (2021). The integration of cutting edge 3D printing technology with detailed CT scan data and intricate surface topography not only enhances treatment accuracy but also streamlines treatment planning processes, reducing treatment time by an estimated 20% and increasing patient throughput by 25%.

Conclusion:

The successful development and evaluation of the 3D printed bolus utilizing surface topography highlights the immense potential of personalized bolus fabrication in the field of radiotherapy. This groundbreaking approach offers clinicians an intricately precise and tailored solution for dose modulation during treatment, thereby potentially leading to significantly enhanced patient outcomes and treatment efficiency.
