[ABSTRAK Dosimeter film Radiochromic XR-RV3 merupakan salah satu tipe dosimeter yangdapat digunakan untuk mengukur dosis pasien pada prosedur kateterisasi jantungdengan fluoroskopi sebagai pemandu. Namun, perlu dipastikan pengaruhkeberadaan film Radiochromic XR-RV3 terhadap kualitas citra. Penelitian inimenggunakan fantom Kat Ped sebagai representasi jantung dewasa danmembandingkan secara kuantitatif kualitas citra fantom yang dieksposi denganmenggunakan film dan tanpa menggunakan film GafChromic XR-RV3. Kuantitasikualitas citra yang digunakan sebagai pembanding adalah Signal to noise ratio(SNR) dan resolusi kontras tinggi. Signal to noise ratio (SNR) yang diperolehdianalisa menggunakan statistik t-test dengan confidence level 95%. Hasil analisamenunjukkan tidak terdapat perbedaan SNR yang signifikan dengan menggunakanfilm dan tanpa menggunakan film pada mode fluoroskopi low dose, normal dosedan high dose dengan diskrepansi SNR <10%. Pada mode cine 15 fps low dan 15fps normal, terdapat kenaikan SNR dengan menggunakan film dengan diskrepansi<13% sedangkan pada mode cine 15 fps boost dan 25 fps coronary tidak terdapatperbedaan signifikan SNR dengan diskrepansi rerata < 7%. Pada high contrastanalisa t-test untuk kedua mode fluoroscopy dan Cine tidak menunjukkan adanyaperbedaan signifikan dengan hasil non rejected pada confidence level 95%.ABSTRACT Radiochromic XR-RV3 film dosimeter is a type of dosimeter that can be used tomeasure patient dose on cardiac catheterization procedure with fluoroscopy as aguide. However, it is necessary to ensure the effect of Radiochromic XR-RV3 filmto image quality. This study used a Kat Ped phantom as a representation of theadult heart and quantitatively compare the image quality by using a phantom thatexposed with film and without using film GafChromic XR-RV3. Quantitation ofimage quality used for comparison is the signal to noise ratio (SNR) and highcontrast resolution. Signal to noise ratio (SNR) obtained statistically analyzedusing t-test with 95% confidence level. The analysis results showed no significantdifference in SNR using film and without using film on a low dose mode, thenormal dose, and high dose flouroscopy with SNR discrepancy <10%. In the cinemode of 15 fps low and 15 fps normal, there is an increased SNR by using filmwith discrepancy <13%, while in the cine mode of 15 fps boost and 25 fpscoronary there are no significant differences with mean SNR discrepancy <7%. Athigh contrast t-test analysis for both Fluoroscopy and Cine mode, result showed nosignificant difference with the results of non-rejected at the 95 % confidence level., Radiochromic XR-RV3 film dosimeter is a type of dosimeter that can be used tomeasure patient dose on cardiac catheterization procedure with fluoroscopy as aguide.
