Automatic Exposure Control

Penelitian ini bertujuan untuk membandingkan nilai dosis radiasi dan kualitas gambar pada pemeriksaan CT Scanurologi non kontras dengan perbedaan teknik Automatic Exposure Control(AEC) dan teknik fixed mA. Desain penelitian ini adalah kuantitatif analitik. Penelitian ini dilakukan di Instalasi Radiologi RS Swasta di Jakarta Utara pada bulan Agustus – Oktober 2019. Jumlah sampel dari penelitian ini adalah 40 orang dengan empat perbedaan perlakuan dan masing-masing perlakuan berjumlah 10 pasien yang dipilih berdasarkan kriteria inklusi dan eksklusi. Metode pengumpulan data yang digunakan berupa observasi dan dokumentasi. Instrumen penelitian yang digunakan yaitu lembar kerja untuk mencatat data selama penelitian berlangsung dan komputer AdvantageWorkstation Computed Tomography ( AWCT) untuk mengukur nilai atau kualitas citra gambar CT Scan.Pengolahan dan analisis hasil data menggunakan program komputasi. Hasil dari penelitian penggunaan teknik Automatic Exposure Control(AEC) dapat memberikan dosis radiasi yang optimal dengan kualitas gambar CT Scan yang lebih baik dibandingkan dengan teknik fixed mA. Meskipun teknik fixed mA100 dapat memberikan nilai dosis radiasi yang lebih kecil dibandingkan teknik AEC tetapi menghasilkan kualitas gambar yang kurang baik

Reduced Dose

The CT Scan is the most significant contributor to radiation dose on radiological examination, although the frequency of the examination is far below other modalities. In order to control this radiation dose, manufactures of CT Scan have equipped their units with built-in software called Automatic Exposure Control (AEC). This study aims to analyze the effect of AEC software, CARE Dose 4D, on image quality, and CTDIvol. Objects used in this study were three water phantoms, each with a diameter of 165 mm, 230 mm, and 305 mm. The image quality-analyzed was CT Number and noise. Measurement of image quality was carried out following Bapeten's provisions. Noise Power Spectrum (NPS) graphics were also used to further observes noise texture. The CT Number accuracy, CT Number, and noise uniformity obtained with and without CARE Dose 4D, on the three phantoms were still within Bapeten's threshold. This indicates that the use of CARE Dose 4D can still image a homogeneous object accurately. The results of the NPS curve showed that the two modes, in three phantoms, were having the same noise texture. The NPS curves also showed that the use of CARE Dose 4D produces higher noise than the non-CARE Dose 4D mode. Meanwhile, there were significant differences from the CTDIvol obtained from the two modes. The use of CARE Dose 4D software reduced dose of up to 54.34%. From this, the use of CARE Dose 4D software can reduce the radiation dose while maintaining image quality.
