Abstract
This study was conducted, to compare ImageJ and Verisoft softwares in EBT2 Gafchromic film dosimetry in High Energy Electron Beam. Film was cut into 3 cm x 3 cm dimension. 6 MeV and 9MeV energy use under Siemens Primus (LINAC), for calibration purpose, the film was exposed to dose 0 cGy to 600 cGy and for measuring FDD and beam profile, another film was irradiated with 400MU monitor unit. The irradiated films were scanned with Epson Expression 10 000XL flatbed scanner. The percentage depth dose (PDD) and beam profile of 6 MeV and 9 MeV electron beams were analyzed by using ImageJ and Verisoft software. Result of this study shows, the discrepancy (% of error) of ImageJ towards Verisoft for all depth are 4.05 % and discrepancy (% of error) comparison between ImageJ software with Ionization Chamber reading are 29.4 %. The highest beam flatness of Verisoft and ImageJ software are 5.88 % and 8 % respectively, the highest penumbra size for Verisoft and ImageJ software are 4 cm both. In conclusions, ImageJ software can be use as software in electron beam dosimetric analysis since it has less percent of error compare to Verisoft software and Ionization Chamber reading.
