CT-Scan, CT-Number, ROI dan keseragaman noise.Abstract
Telah dilakukan penelitian tentang analisis sensitivitas dalam deteksi homogenitas ROI pada pengukuran kualitas citra pesawat CT-Scan. Penelitian ini bertujuan untuk memperoleh verifikasi metode baru untuk mengevaluasi homogenitas citra CT-Scan dengan cara mencari nilai CT-Number pada 12 titik (posisi arah jam 1 sampai jam 12) dengan analisis 6 area ROI berupa grafik atau histogram serta membandingkan hasilnya dengan metode pada umumnya yaitu pada hasil citra pesawat CT-Scan di area ROI pada posisi arah jam 12, jam 3, jam 6, jam 9 dan pusat fantom sehingga dapat mengetahui tingkat sensitivitas kedua metode tersebut dalam mendeteksi homogenitasnya. Pengambilan data yaitu data sekunder dari hasil citra fantom air pada CT-Scan sebanyak 30 citra yang diperoleh dari Pusat Riset Teknologi Keselamatan, Metrologi dan Mutu Nuklir-Organisasi Riset Tenaga Nuklir-Badan Riset dan Inovasi Nasional (PRTKMMN-ORTN-BRIN). Hasil pengukuran menunjukkan bahwa nilai keseragaman noise dari 30 data sampel terdapat 21 data sampel memenuhi batas toleransi yaitu ≤ 2 HU. Hasil ini memenuhi standar perka BAPETEN No. 2 Tahun 2018 tentang uji kesesuaian pesawat sinar-X radiologi diagnostik dan intervensional. Perbandingan sensitivitas dalam mendeteksi homogenitas ROI pada pengukuran kualitas citra pesawat CT-Scan menunjukkan bahwa metode ROI pada penelitian ini mampu menghasilkan sensitivitas yang lebih baik dalam mendeteksi homogenitasnya.
