Abstract: SNR test is one of the quality controls on Magnetic Resonance Imaging (MRI). This study used MRI 1.5T GE Signa Creator type and head coil phantom with variations of Echo Time (TE), Repetition Time (TR), voxel volume and flip angle. 16 data images were obtained from acquisition process. These images were analysed using image processing software by measuring pixel values in each image. The SNR value of the sample number produced four data distribution with the highest value of 36.98 and the lowest value of 32.64. The graphs of voxel volume versus SNR also formed four groups of data with overall value above SNR baseline value for daily operation.
Uji SNR merupakan salah satu kontrol kualitas pada MRI (Magnetic Resonance Imaging). Telah dilakukan uji SNR dengan modalitas MRI 1.5T merk GE tipe Signa Creator menggunakan head coil phantom dengan variasi TE, TR, voxel volume dan flip angle dan 16 sampel data. Citra hasil scan phantom dianalisa menggunakan software pengolahan citra dengan mengukur nilai pixel pada masing-masing citra. Nilai SNR terhadap nomor sampel menghasilkan empat sebaran data dengan nilai tertinggi sebesar 36.98 terdapat pada variasi sampel nomor sembilan, nilai terendah sebesar 32.64 terdapat pada variasi sampel nomor empat. Grafik hubungan voxel volume terhadap SNR juga membentuk tiga kelompok data dengan keseluruhan nilai diatas nilai batas untuk uji harian.
