Abstract

Proton therapy modeling for treating craniopharyngioma tumors was conducted using a pencil beam collimator, and variations in beam directions were performed using MCNP6 software. The simulation was carried out on a head and neck phantom with the tumor cells modeled within a cubic irradiation area geometry with a 1.2 cm side length, divided into 27 small cubic voxels with a small voxel side length of 0.4 cm. The radiation source from the irradiation area's right, left, and top directions, with a diameter of 0.4 cm, was directed at each cubic voxel. Variation in radiation source directions indicated that irradiation from the right direction of the irradiation area is the most recommended approach, with a dose uniformity level of 83.47%. Healthy organs surrounding the irradiation area received lower doses than those obtained by tumor cells, and the majority remained below the Organ At Risk (OAR) threshold. Healthy organs received the highest dose, particularly in the brain region, at a relative 0.46% compared to the total dose received by tumor cells.

Abstract

ABSTRACT: The Rekso Pustoko Mangkunegaran Library has various types of historical manuscripts, covering history from ancient to modern periods. The existence of these collections is certainly very useful for writing history, especially the history of Java. Unfortunately, there are still many historical researchers in Indonesia who use colonial archival sources such as Besluit, Algemeen Verslag, Memorie van Overgave and documents such as Staatsblad, Rijksblad and Regeering Almanac instead of using existing historical manuscripts. This is due to the difficulties experienced by historical researchers in reading manuscripts which in terms of material are written by hand and use Javanese language and letters. To overcome this problem, it is necessary to catalog the manuscripts. The catalog of historical manuscripts in addition to containing the manuscript code number also contains a synopsis of the contents of the manuscript. This, in addition to making it easier for researchers to find manuscripts, also helps in understanding the contents of historical manuscripts from the Rekso Pustoko Mangkunegaran collection. The purpose of this service is to catalog the historical manuscripts of the Rekso Pustoko Mangkunegaran collection. ABSTRAK: Perpustakaan Rekso Pustoko Mangkunegaran mempunyai berbagai jenis manuskrip sejarah, meliputi sejarah dari periode kuno hingga modern. Keberadaan koleksi-koleksi ini tentu sangat bermanfaat bagi penulisan sejarah terutama sejarah Jawa. Sayangnya, masih banyak peneliti sejarah di Indonesia yang lebih banyak menggunakan sumber arsip kolonial seperti Besluit, Algemeen Verslag, Memorie van Overgave maupun dokumen seperti Staatsblad, Rijksblad dan Regeering Almanak dibandingkan memanfaatkan manuskrip sejarah yang ada. Hal ini dikarenakan kesulitan yang dialami peneliti sejarah dalam membaca manuskrip yang dari segi material ditulis dengan tangan serta menggunakan bahasa dan huruf Jawa. Untuk mengatasi masalah ini diperlukan upaya katalogisasi manuskrip. Katalogisasi manuskrip sejarah selain berisi nomor kode manuskrip juga berisi sinopsis dari isi manuskrip. Hal ini selain mempermudah peneliti dalam menemukan manuskrip juga sekaligus membantu dalam memahami isi manuskrip sejarah koleksi Rekso Pustoko Mangkunegaran. Tujuan dilakukannya pengabdian ini adalah untuk membuat katalog manuskrip sejarah koleksi Rekso Pustoko Mangkunegaran.

Abstract

The alpha therapy modeling was performed for the treatment of glioblastoma brain cancer using MCNP6 software. The simulation used a head and neck phantom geometry, with a spherical shape of the radiation direction of the cancer cells with a radius of one cm divided into 27 targets. One radiation source is directed to each target center of the cancer cells with five energy variations, namely (430, 425, 415, 410, and 400) MeV. The simulation results are in the form of a distribution of absorbed doses in all targets and healthy cells around them. The simulation results show an average dose distribution of (1.2902 ± 0.0024) 10-11 Gy/alpha with an isodose level of 69.75%. The healthy organ that receives the largest dose and secondary particle distribution after cancer cells is the brain, with an accumulative dose of (1.7446 ± 0.0033) 10-15 Gy/alpha. The dose distribution on cancer cells shows that the irradiation time to kill glioblastoma cancer cells is (1456±0.14) seconds with an alpha current of 1 nA.

Abstract

This study was conducted with simulation modeling on alpha therapy for the treatment of craniopharyngioma tumors using the reference head and neck phantom geometry from Lazarine (2006), which was equipped with spherical target cell geometry. The target cell geometry with a radius of 1.05 cm contains 27 partitions located at the base of the brain close to the spine. This simulation was performed using pencil beam scanning which has a beam size of 0.35 cm and was irradiated from the left direction as far as 25 cm from the skin surface by giving 5 variations of energy ranges 425, 430, 440, 445 and 450 MeV. The results of the simulation obtained an average absorbed dose of (1.30 ± 0.01) x 10-9 Gy/α with an isodosis rate of 62%. In addition, this study also takes into account the dose received by healthy cells around the tumor. The brain organ received the largest dose of (2.69 ± 0.01) x 10-13 Gy/α, when compared to the brain tumor cells received a dose of 0.021%. From the dose distribution to tumor cells, the irradiation time for craniofaringioma tumors is (13.3 ± 0.01) s with an α particle current of 1nA.

Abstract

Abstract. A brain tumor (Glioma Cerebri) is an abnormal growth and division of cells in the skull cavity. There are many tumor therapies, namely surgery, chemotherapy, and radiotherapy. Gamma knife is effective radiotherapy in brain tumours and requires a careful Treatment Planning System (TPS) regarding the absorbed dose. This study reports the results of simulations using software MCNP6 by modelling tumour cells in the shape of a ball with a diameter of 1 cm and located in the centre of the brain. The source of the -radiation is the isotope Co-60, emitting from the source point with isotropically, the distance from the source to the phantom surface (SSD) is 40.1 cm. The phantom is a head and neck containing material that makes up soft tissue and bone. The proton beam guiding collimator has a size according to the helmet collimator diameter, namely 1.25 mm, 2.5 mm, 4.25 mm, and 5.3 mm. The simulation resulted in the absorbed doses in tumour cells (6.17±0.37) mGy, (10.73±0.45) mGy, (10.87±0.45) mGy, and (10.89±0.45 ) mGy. The amount of scattered dose outside the tumour cells has been measured, and the enormous value is in the brain organ with a hefty dose (25.60±1.96) mGy, (122.29±1.41) mGy, (398.20±7.75) mGy, and (597.65±6.18) mGy. Evaluation of the organ dissipated dose is in the safe category. The total irradiation time required is (40.5±2.4) minutes, (23.4±1.0) minutes, (23.0±1.0) minutes, and (22.9±0.9) minutes.Abstrak: Tumor otak (Glioma Cerebri) merupakan suatu pertumbuhan dan pembelahan sel yang tidak wajar pada rongga tengkorak.

Abstract

Abstract:. Proton characteristics in simulation of proton therapy in nasopharyngeal carcinoma were performed using MCNP6 software simulation. The nasopharyngeal carcinoma cell was modelled as a sphere with a diameter 1,56 cm. The proton beam energy used was 103 – 109 MeV fired at the carcinoma cell from two different directions, right and left. From the simulation result, the equivalent dose of cancer cells was (0,247 ± 0,002) Sv with a dose distribution in the facial skeleton, soft tissue, skin, skull, spine, and brain. The results were still within the safe limits of Organ At Risk (OAR). With the current used of 10 nA, the total duration of three treatment time for therapy was (8,10 ± 0,01) minutes.Abstrak: Karakteristik proton untuk simulasi terapi proton pada karsinoma nasofaring dilakukan dengan simulasi perangkat lunak MCNP6.
