UJI KESESUAIAN PESAWAT PANORAMIC CHEPALOMETRIC DI LABORATORIUM JURUSAN TEKNIK RADIODIAGNOSTIK DAN RADIOTERAPI, POLTEKKES KEMENKES SEMARANG (UJI MENGGUNAKAN FILM GAFCHROMIC)

Background: X-ray equipment used for radiographic examination according to Bapeten regulations must undergo a compliance test, both new installation and relocating. The Panoramic Chepalometry in the Department of Radiodiagnostics Radiotherapy Techniques Semarang is device has undergone relocation from initial installation. In addition, unique condition direct image processing or radiography, so special method needed testing x-ray collimation beams, namely using gafchromic films
 Methods: research experimental with one shot case study at Laboratory Radiodiagnostic Techniques, Poltekkes Kemenkes Semarang. object cephalometry device. measuring instrument was Raysave, test parameters measured were: beam, voltage accuracy, time linearity, reproducibility, HVL, tube container leakage. analysis results adjusted regulation no. 2 2018
 Results: Parameter obtained: beam still within normal limits, accuracy measurement obtained maximum error 2.73% (max. limit 6%), 7.8% 10 %), linearity not because mA value fixed, reproducibility CV 0.0012 radiation output 0.0006 (CV≤ 0.05), quality (HVL) 3.72 mm Al 80 kVp (HVL ≥ 2.3 Al), no leakage housing
 Conclusions: panoramic cephalometric Semarang, on 7 as whole are limits Perka no.2 2018
