Abstract

This study aims to obtain Quality Control information on the quality of the photon beam and radiation field used for the maximum depth value (Zmak) from the results of Percentage Depth Dose measurements as well as the symmetry and flatness values ​​from the results of profile dose measurements using symmetric and asymmetric radiation fields of (10x10) cm2 and (15x15) cm2 with AAPM TG-40 standards. The results of Quality Control carried out on the LINAC show that the greater the photon beam energy and the area of ​​the field given, the greater the maximum depth value (Zmak) obtained. In the profile dose measurement, the largest symmetry value was obtained in the 1 cm offset section of 2.8% for 6 MV energy using the (10x10) cm2 field and the largest flatness value in the 3 cm off-set section of 1.9% while for 10 MV energy the largest symmetry value in the 3 cm off-set section was 4.3% and the largest flatness value in the 1 cm off-set section was 2.3%. In the field area (15x15) cm2, the largest symmetry values ​​of 6 MV and 10 MV energy were obtained at the 3 cm off-set section of 3.7% and 4.3%, and the largest flatness values ​​of 6 MV and 10 MV energy were found at the 3 cm off-set section of 2.3% and 2.1%. Therefore, the symmetry and asymmetry fields (1 cm off-set) on the LINAC are reliable enough to be used in cancer therapy treatment.

Abstract

Nobita Hill is one of the areas being developed as a tourist attraction in the city of Padang. Above Nobita Hill is a beautiful view, and you can see the picture of Padang City. However, the hilly topography with steep slopes makes this area prone to landslides. This activity aims to map the potential for landslides on Novita Hill. Activities start from preparation, implementation in the field, and evaluation. Field activities are carried out in two stages. The first stage is an experiment to map the landslide potential. The second stage is socialization. The target audience for this activity is the Village Head of Jua Nan XX Village and its officials and the community around Nobita Hill. The results of the study and mapping were disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area, which was carried out on November 16, 2022. The result of tourist objects often changes land use and cover. However, mitigation of the potential for landslides in this area has never been done. Therefore, the Andalas University Physics Department team mapped the potential for landslides on Novita Hill for six months, using microseismic and geoelectric methods. This activity obtained a map of the distribution of dominant frequencies, a map of the distribution of amplification, and an identification of slip planes concerning the potential for landslides on Nobita Hill. Furthermore, the results of the mapping and mitigation efforts have been disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area. This activity was carried out well. The landslide potential distribution map obtained from this activity is input for the community and stakeholders in developing the Buki Nobita tourist attraction that is safe from disasters.

Abstract

This study aims to compare the results of Monte Carlo simulations using PRIMO software with the results of experimental measurements in the QA process of a 6 MV Varian Clinac CX Linear Accelerator (LINAC) photon beam based on the parameters of Percentage Depth Dose (PDD), dose profile, and gamma index. Dose distribution measurements were performed using a water phantom at a Source to Surface Distance (SSD) of 100 cm with field sizes of 4×4 cm², 10×10 cm², and 40×40 cm². Monte Carlo simulations were performed using PRIMO software by modeling the geometry of the Varian Clinac CX LINAC head and water phantom according to the experimental conditions. The simulation and measurement results were analyzed through PDD curves, dose profiles, and quantitative evaluation using the gamma index with a tolerance criterion of 2%/2 mm. The results showed that the simulated PDD curves were in good agreement with the measurement results. The gamma passing rate values obtained were 97.98% for the 4×4 cm² field, 97.43% for the 10×10 cm² field, and 87% for the 40×40 cm² field. The decrease in conformity in large fields is influenced by an increase in the contribution of lateral scattering. The dose profile analysis results show conformity in the central area of the field, while greater differences occur in the penumbra and shallow depths due to steep dose gradients and detector resolution limitations. PRIMO-based Monte Carlo simulation can be relied upon as an independent verification instrument in the routine quality assurance of 6 MV photon beams from the Varian Clinac CX LINAC

Abstract

The aim of this study is to verify the adequacy of the surface radiation dose calculated by the Treatment Planning System (TPS) using 3DCRT and IMRT technique with the dose measured by the TLD-100, referring to the report of the American Association of Physicists in Medicine Task Group No.219 (AAPM-TG No.219). This research process began with annealing the TLD-100 at the Research Center for Safety Technology Metrology and Nuclear Quality of the National Innovation Research Agency (PRTKMMR-BRIN), followed by scanning the TLD-100 on the surface of the phantom plate using a CT simulator. In addition, the TLD-100 was calibrated with different radiation doses (0; 20; 50; 80; 100; 150; 200; 250; 370) cGy. Verification of the surface radiation dose was performed by calculating the TPS surface dose by Patient Specific Quality Assurance (PSQA) and comparing it with the dose measured by the TLD-100. The result is Radiation techniques such as IMRT are more conformal than 3D-CRT because they precisely control dose intensity, making the TLD dose in IMRT closer to TPS. Differences in detector types such as TLD also affect the results of radiation dose measurements. Continuous assessment of patient dose is important for the safety of radiation therapy.

Abstract

The manufacture and characterization of beeswax bolus with various petroleum jelly mass compositions using a thermal mixing method has been carried out. Boluses measuring 10×10 cm with a thickness of 1.0 cm were characterized based on physical properties (density and water absorption), mechanical (tensile strength, strain, and elastic modulus), Relative Electron Density (RED), and absorbed dose. The results showed that the mass composition significantly influenced the bolus characteristics. The sample with a composition of 90:30 had a density of 0.966 g/cm³ which was closest to soft tissue, while the water absorption was in the range of 7.22– 8.54% with the lowest value at the composition of 85:35. Increasing the petroleum jelly content decreased the tensile strength and elastic modulus (1138–2251 MPa), indicating that the material became more flexible. Measurement of the absorbed dose at electron energies of 6 and 9 MeV and RED analysis of CT images showed that the dosimetric response was influenced by the mass composition, with certain RED values equivalent to breast tissue. Overall, the 85:35 composition provides the closest characteristics to human soft tissue and has the potential to be used as a radiotherapy bolus.
