Analisis Indeks Paparan Radiografi Digital Pada Pemeriksaan Radiologi Thoraks Postero Anterior Sebagai Upaya Peningkatan Proteksi Radiasi Pasien

ABSTRACT Backgound: Digital radiography is an easy method of radiological examination, so many radiology technicians often use high exposure factors because they are considered to speed up when processing images, this can increase the risk excessive radiation doses in patients, currently index (IE) feedback for optimal images and low patients. Objective: evaluating Fujifilm (S-Value) entrance surface dose (ESD) thorax posterior-anterior as effort patient protection using ALARA principle, Method: Data taken from samples with parameters 64 kVp 16 mAs 94 2 mAs, ESD measured thermoluminescent dosimeter (TLD) chip Fujifilm's direct device. Result: The relationship between S-Value has exponential trend graph. rise will be followed by sequence. With BAPETEN reference value 0.40 mGy, minimum S-value must achieved that patient's does not exceed S-532 at 0.39. Conclusion: results study indicate allows it used evaluation values received patients protection. Keywords: Exposure (S-Value), ESD, chest radiography,
