Penelitian ini bertujuan untuk menghitung nilai dosis efektif (DE) Computed Tomographt Scanning Paru-Paru Menggunakan Software IndoseCT v20b. Data perhitungan yang akan dibandingkan dengan perhitungan seacara matematis sebanyak empat data DICOM dianalisis dengan lima slices per pasien. Metode yang digunakan pada penelitian ini adalah metode perhitungan secara matematis dan software IndoseCT v20b. Hasil menunjukkan bahwa nilai DE dari software lebih rendah dan konsisten dibandingkan secara matematis, dengan rata-rata perbedaan sebesar ±43,3% dengan rentang antara ±35%–61,5%. Dosis radiasi Software IndoseCT v20b didapatkan masih dibawah standar BAPETEN, sehingga direkomendasikan digunakan untuk menghitung pengelolaan dosis radiasi pasien.

The effective dose (ED) of lung computed tomography (CT) scans was calculated using IndoseCT v20b software and compared with values obtained through manual mathematical calculations. A total of four DICOM datasets were analyzed, with five image slices evaluated per patient. The methode used in this case is calculated with mathematics and software IndpseCT v20b. The findings revealed that the ED values generated by the software were consistently lower and more uniform than those obtained mathematically, with an average percentage difference of ±43.3%, ranging from ±35% to 61.5%. Additionally, the radiation dose estimates provided by IndoseCT v20b remained below the reference limits established by BAPETEN. These results support the use of IndoseCT v20b as a reliable tool for estimating and managing patient radiation exposure in clinical CT imaging.
