Abstract

Salah satu prosedur penting dalam perencanaan radioterapi eksternal (Treatment Planning System) adalah penentuan area kanker primer (Gross Tumor Volume / GTV) dan penyebarannya. Penentuan kanker dilakukan secara teliti melalui prosedur Treatment Planning System. Penelitian ini melakukan segmentasi area kanker primer berdasarkan nilai bilangan CT (BCT) yang diidentifikasi dari hasil citra CT–Scan pasien. Rentang nilai BCT kanker ditentukan dengan teknik analisa statistik deskriptif dari data numerik yang diperoleh dari file DICOM (Digital Imaging and Communications in Medicine) CT–Scan. Hasil penelitian menunjukkan bahwa nilai BCT = +31 HU sampai dengan +38 HU mengindikasikan lokasi tumor astrositoma di bagian kiri otak pasien PX–1. Nilai BCT = +7 HU sampai dengan +45 HU pada pasien PY–1  menunjukkan area hipodensitas pada GTV kanker serviks. Sedangkan nilai BCT = +6 HU sampai dengan +49 HU pada pasien PX–2 menunjukkan densitas yang relatif homogen pada area CTV (Clinical Target Volume) kanker serviks. Kata Kunci : Bilangan CT, DICOM, CT–Scan, astrositoma, kanker serviks, radioterapi eksternal

Abstract

The implementation of Patient-Specific Quality Assurance (PSQA) is crucial for ensuring the accuracy and safety of Intensity-Modulated Radiation Therapy (IMRT). This study evaluates the application of AAPM TG-218 recommendations in PSQA for thoracic region treatment using the IMRT technique. The study compares two PSQA methods, Perpendicular Composite (PC) and Perpendicular Field-by-Field (PFF), using Electronic Portal Imaging Device (EPID). Measurements were conducted on 10 IMRT patients using a Varian TrueBeam Linac and Eclipse TPS. The Gamma Index (GI) analysis with criteria 3%/3 mm, 3%/2 mm, and 2%/2 mm was used to assess dose distribution accuracy. The results indicate that the average Gamma Passing Rate (GPR) for 3%/2 mm criteria exceeded 95%, which is appropriate with AAPM TG-218 standards. However, stricter criteria (2%/2 mm) did not reach the minimum recommended values. The study suggests that PSQA using EPID with the PFF method under rotational gantry conditions is the most suitable approach for thoracic IMRT treatment verification. The local standardization recommendations from the results of this study can be used as a reference for determining methodological standards in cases of the thoracic region in the IMRT technique to increase efficiency in clinical applications with similar PSQA dosimetry.
