Abstract

The delivery of radiation therapy to patients requires prior planning made by medical physicists to achieve radiotherapy goals. Radiotherapy has a plan to eradicate the growth of cancer cells by giving high doses and minimizing the radiation dose to normal tissue. Evaluation of planning is generally done based on dosimetric parameters, such as minimum dose, maximum dose, and means dose obtained from the DVHs data. Based on the same DVHs, data were evaluate dinterms of biological effects to determine the highest possible toxicity in normal tissue after the tumor had been treated with radiation using the NTCP model. The evaluation was conducted by selecting three DICOM-RT data of post-mastectomy right breast cancer patients who had been prescribed a dose of 50 Gy obtained from the Hospital MRCCC Siloam Semanggi database. All data were processed using open-source software DICOManTX to get the DVH and isodose information. Matlab-based CERR software was used to calculate the NTCP model. The results show that the three patients' DVH and isodose treatment planning result in a homogeneous dose distribution result because the PTV area obtains adose limit of ≥ 95%. Moreover, normalt issue still gets adose below the tolerance limit based on the standard from RTOG 1005 and ICRU 83. Analysis of NTCP shows a complication probability below 1% for each organ, suggesting that any organ which has been irradiated has a low likelihood of complications. Therefore, it can be concluded that the treatment planning which has been made in the three patients using the IMRT technique has achieved the objectives of radiotherapy, which is to minimize toxicity to healthy organs. |Keywords: DVH, isodose, NTCP, radiotherapy.

Abstract

THE ADVANCED ELECTRIC FIELD FROM QUAD-ELECTRODE MODE FOR BLOOD CANCER TRAPPING: SIMULATION STUDY. Blood cancer is a disease caused by the rapid cleavage of white blood cells (WBC), which increases in the human circulatory system. Furthermore, based on the original nature of WBC during cleavage, which is the same as ionic bonds, electric field filtering, and trapping is used to treat leukemia patients. The electric field generated by the electrode with an AC voltage source plays a role in the migration of the WBC to high electric field intensity. The Quad-electrode field distribution is conducted using the Finite Element Method (FEM), and an electric field gradient analysis is conducted to determine the effectiveness of each coordinate system. According to the simulation results, the second model with an input voltage of 0.68 V has the highest intensity of electric field distribution, with an effective depth at Z = 30 mm, and the best coordinate along the X-axis and Y-axis are 30 mm. In conclusion, the center of the Quad-electrode system center is the best location for placing filters and trapping leukocytes by utilizing electric field distribution on the electrode system for the development of blood cancer biomedical therapy technology.

Abstract

3D printing technology was capable of fabricating phantoms to enhance quality assurance in radiation therapy. The ideal phantom has properties equivalent to the real tissue. However, 3D Printing has the limits to mimicking the attenuation properties of various tissues because during 3D printing there can be only one type of material. The purpose of this study was to evaluate the effect of infill percentage and infill patterns of 3D printing technology to simulate various types of tissue. This study used 25 samples measuring 5 × 5 × 1 cm3 from PETG material. The 20 samples were printed using variations infill percentages from 5 - 100% and the infill pattern in lines. The five samples were then printed with the infill percentage constant at 50% and used the infill pattern triangles, grid, gyroid, octet, and concentric. We used Computed Tomography (CT) to determine the Hounsfield Unit (HU) value for each sample and evaluated the suitability of each sample for phantom applications in radiation therapy and radiology. However, none of the samples was able to simulate compact bone. As a result, we found that PETG material could simulate the properties of soft tissue, fat, lung, kidney, liver, pancreas, and spongy bone. Thus, the study had shown promising potential for the fabrication of the anthropomorphic phantom of radiation therapy.

Abstract

This study aims to evaluate the automated measurement of slice sensitivity profile (SSP) on the American Association of Physicists in Medicine (AAPM) computed tomography (CT) performance phantom for variations of slice thickness and field of view (FOV). The AAPM CT performance phantom was scanned using a Philips MRC 880 CT Scanner for variations of slice thickness and FOV. The slice thickness values were 1, 3, and 5 mm. The FOV values were 240, 300, 340, 400, and 440 mm. The automated SSPs and their fullwidth at half maximums (FWHMs) were automatically measured from the middle stair object of the phantom. To validate the automated measurement results, the FWHM values of SSPs obtained were compared to those from manual measurements. The differences between FWHMs from automated measurements and set slice thicknesses are less than 0.3 mm, while the differences between FWHMs from automated and manual measurements are less than 0.2 mm. The results from automated measurements are closer to the set slice thickness than those from manual measurements. This automated SSP measurement provides high accuracy and precision for both the slice thickness and the FOV variations.

Abstract

Penulisan karya tulis dan karya ilmiah di bidang pendidikan merupakan salah satu bentuk pengembangan profesi dari seorang guru yang dapat berkontribusi pada peningkatan mutu pendidikan dalam proses belajar mengajar. Namun jumlah karya ilmiah yang dihasilkan oleh keprofesian guru masih berada di angka yang rendah. Salah satu kesulitan penulisan karya ilmiah yang dialami oleh para guru adalah pengembangan ide atau pemikiran menjadi sebuah tulisan karya ilmiah yang koheren dan padu. Untuk itu, perlu dilakukan pelatihan penulisan artikel ilmiah dalam bentuk laporan penelitian maupun penulisan artikel dalam jurnal ilmiah. Hal ini diharapkan dapat meningkatkan dan menambah kemampuan seorang guru yang fasih dalam keterampilan bahasa verbal menjadi terampil juga dalam menuangkan ide dan pemikirannya dalam bentuk tulisan. Sejumlah guru terutama guru muda yang mengajar di SMA A. Wahid Hasyim Tebuireng menjadi target utama dalam pelatihan ini. Pelatihan ini diharapkan dapat memberikan pemahaman mengenai metode penulisan artikel ilmiah yang baik dan berkualitas, meningkatkan motivasi guru dalam menulis artikel ilmiah, serta menghasilkan naskah/artikel oleh guru yang layak dipublikasikan.

Abstract

Undang-Undang Nomor 33 Tahun 2014 Tentang Jaminan Produk Halal telah berjalan. Namun sejumlah kebijakan dari produk hukum tersebut masih belum tersosialisasikan dengan baik, terutama bagi kalangan pelaku usaha di sektor makanan dan minuman UMKM. Begitu juga yang terjadi pada sebagian penggiat UMKM di Kabupaten Madiun yang belum tahu menahu mengenai kebijakan tersebut. Mereka kurang kesadaran bahwa mengurus perizinan dan sertifikasi halal terhadap produk mereka adalah suatu hal yang sangat penting dan tentunya akan memberikan banyak manfaat bagi keberlangsungan usaha mereka. Permasalahan muncul tidak hanya dari sisi sosialisasi kebijakan, namun juga dari sisi literasi pelaku UMKM dalam hal proses produksi halal yang masih rendah. Dari permasalahan tersebut, penulis mengusulkan solusi dalam bentuk sosialisasi, pembinaan, dan pendampingan kepada UMKM di Madiun terkait proses produksi halal dan sertifikasi halal. Dengan demikian, program-program tersebut diharapkan dapat membantu UMKM khususnya di Kabupaten Madiun untuk mendapatkan sertifikat halal bagi produknya sehingga mampu memberikan nilai tambah dan secara tidak langsung ikut mendukung berlangsungnya kebijakan jaminan produk halal.

Abstract

The purpose of this study was to evaluate the effect of rectangular region of interest (ROI) size on modulation transfer function (MTF), to develop the radial ROI, and to compare both ROIs performances for MTF measurement using a cylindrical polymethyl methacrylate (PMMA) phantom. The PMMA phantom used in this study was rotated 45°. Four rectangular ROIs and a radial ROI were created to measure the MTF value. The rectangular ROI sizes were 3×41, 21×41, 41×41, and 61×41 pixels; each was placed at upper phantom edge. The radial ROI’s length was 41 pixels and placed at several points in phantom edge. The MTF calculation was automatically conducted using MATLAB. The MTFs from rectangular ROIs and radial ROI were then compared. The comparison of the MTF measurement was also conducted using three different filters. The MTF which used radial ROI was smoother than those of rectangular ROI for all filters. This indicated that radial ROI was more resistant to noise than rectangular ROI. Rectangular ROI with the 41×41 pixels had similar 50% and 10% MTF values with the radial ROI. The MTF value which was obtained using radial ROI is more accurate and robust than those obtained using rectangular ROI.
