ANALISA KUALITAS RADIORGRAF TERHADAP NILAI INDEKS EKSPOSUR STUDI PADA PASIEN PEDIATRIK PEMERIKSAAN BABY GRAM

Abstract

A child's body is still growing, making it more radiation-sensitive. Radiographic examinations such as baby gram X-rays in children must pay attention to the ALARA principle (as low as reasonably achievable). The radiograph results will produce good quality and pay attention to the child's radiation dose. This study aims to analyze the exposure index's value in selecting exposure factors for babygram radiographic examination. An assessment is also carried out on the radiograph's noise value to assess the image's excellent quality in the study. This research is quantitative with an experimental design. The analysis was carried out at Arifin Achmad Regional Hospital, Riau Province. The research method is to produce two radiographs from a baby gram X-ray examination with a predetermined exposure factor. The assessment is done by looking at the exposure index and noise values produced on each radiograph. Exposure factors influence sensitivity values, dose values, and noise values. The sensitivity value can determine the value of the dose released. Sample 1, with exposure factor setting kV 65 and mAs 2.5, obtained a sensitivity value of 76 and produced a dose value of 2,631 mR. Sample 2, with exposure factor setting kV 45 and mAs 4, got a sensitivity value of 241 and a dose value of 0.828 mR. Noise value is lower in sample 2.
