Abstract

Telah dilakukan penelitian tentang analisis nilai noise dari citra pesawat CT-Scan pada beberapa

rekonstruksi kernel dengan variasi slice thickness. Penelitian dilakukan dengan menggunakan fantom sebagai bahan pengganti pasien. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan rekonstruksi kernel terhadap nilai noise. Nilai noise ysng didapatkan dibandingkan dengan batas toleransi yang diizinkan oleh BAPETEN. Slice thickness terbaik akan ditentukan dari masing-masing rekonstruksi yang digunakan. Penelitian dilakukan pada arus 250 mAs dan tegangan 120 kV dengan menggunakan rekonstruksi kernel standar, lung, soft, edge, bone dan chest serta variasi slice thickness dari 1 mm – 10 mm. Hasil analisis menunjukkan bahwa perbedaan rekonstruksi kernel yang digunakan memberikan pengaruh berupa peningkatan nilai noise. Nilai noise yang didapatkan masih dalam batas toleransi yang diizinkan oleh BAPETEN. Slice thickness yang paling baik adalah dengan ketebalan 6 mm, karena pada ketebalan ini dihasilkan nilai noise yang paling sedikit. Penggunaan slice thickness yang tidak terlalu tebal akan membuat citra menghasilkan detail-detail gambar yang tinggi dan sebaliknya, untuk itu perlu adanya optimasi penggunaan slice thickness agar bagian tubuh yang menjadi objek pemeriksaan dapat didiagnosis dengan baik.
