by ADMIN 115 views

Introduction

Radiotherapy is a crucial treatment modality in cancer management, where high-energy radiation is used to destroy cancer cells. However, the effectiveness of radiotherapy depends on the accurate delivery of radiation doses to the tumor tissue while minimizing damage to surrounding healthy tissues. Bolus radiotherapy is a technique used to increase the dose of radiation to tumor tissue by creating a physical barrier that absorbs radiation and directs it towards the tumor. In this study, we aim to characterize silicone rubber, alginate, and wood sawdust as a radiotherapy bolus in 8 MeV and 10 MeV energy.

Background

Bolus radiotherapy has been used for decades to enhance radiation doses to tumor tissue. The process of making radiotherapy bolus involves filtering wood sawdust powder through a 200 mesh filter and mixing it with other materials such as silicone rubber, alginate, and bluesil catalyst. The resulting mixture is then printed into a specific size and dried in an oven at a temperature of 30°C. The melting method of intercalization is used to produce radiotherapy bolus.

Materials and Methods

The materials used in this study include silicone rubber, alginate, wood sawdust, and bluesil catalyst. The production of radiotherapy bolus involves filtering wood sawdust powder through a 200 mesh filter and mixing it with other materials. The resulting mixture is then printed into a specific size and dried in an oven at a temperature of 30°C. The physical properties of the radiotherapy bolus, including density, porosity, and water absorption, were measured using a density meter, porosity meter, and water absorption meter, respectively. The mechanical properties, including tensile strength, modulus of elasticity, and extension, were measured using a tensile testing machine. The performance properties, including relative electron density and surface dose absorption, were measured using a relative electron density meter and surface dose absorption meter, respectively. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to analyze the structure and chemical composition of the radiotherapy bolus.

Results

The results of the physical properties show that the optimal density value is 1.80 g/cm³, 20% porosity, and 12.5% water absorption. The mechanical properties show optimal tensile strength of 0.85 MPa, modulus of elasticity of 0.66 MPa, and extension of 198.24%. The performance properties show relative electron density of 1.26 and surface dose absorption of 113.27% and 113.48% in 8 MeV and 10 MeV energy, respectively. SEM analysis shows an average pore diameter of 21.25 μm. FTIR analysis shows the peak at 3384.97 cm⁻¹ in accordance with the O-H function cluster, 2962.8 cm⁻¹ for the C-H function cluster, 1256.64 cm⁻¹ for the CO function group, 1014.01 cm⁻¹ for the Si-O-Si function cluster, and 790.14 cm⁻¹ for the Si-CH functional cluster.

Discussion

The results of this study indicate that the combination of silicone rubber, alginate, and wood sawdust has the potential as an effective radiotherapy bolus. The optimal density, porosity, and absorption of water indicate the ability of the material to absorb radiation doses efficiently and distribute them correctly. Tensile strength, optimal modulus of elasticity, and extension indicate that this radiotherapy bolus has a good resistance to deformation and can maintain its shape during the therapy process. Relative electron density and optimal surface dose absorption indicate the ability of materials to absorb radiation energy effectively and distribute them to tumor tissue appropriately. SEM and FTIR analysis provides further information about the structure and chemical composition of radiotherapy bolus, which is important for understanding the mechanism of radiation absorption and interaction with tissue.

Conclusion

The results of this study indicate that the combination of silicone rubber, alginate, and wood sawdust has the potential as an effective radiotherapy bolus. This material has optimal physical, mechanical, and performance properties to absorb radiation doses efficiently and distribute them to tumor tissue precisely. Further research is needed to test the performance of this radiotherapy bolus in clinical conditions and validate its potential as an alternative to radiotherapy bolus that is more affordable and easily accessible.

Limitations

This study has several limitations. The production of radiotherapy bolus was limited to a specific size and shape, which may not be representative of the actual clinical conditions. The physical and mechanical properties of the radiotherapy bolus were measured using a limited number of samples, which may not be representative of the entire population. The performance properties of the radiotherapy bolus were measured using a limited number of samples, which may not be representative of the entire population.

Future Directions
