METHOD AND APPARATUS FOR ANALYZING RELATIVE DOSE OF RADIOACTIVE RAYS USING GAFCHROMIC FILM

摘要

A method and an apparatus for analyzing relative radiation dose using a Gafchromic film are provided to analyze relative radiation dose rapidly and find the Bragg peak of the radiation easily by analyzing the entire region of the Gafchromic film in which the radiation is irradiated. A method for analyzing relative radiation dose using a gafchromic film comprises: a step(S400) scanning the Gafchromic film in which the radiation is irradiated; a step(S410) which produces an scan image file and indicates the scan image file on a screen; a step(S420) extracting pixel extraction information from the scan image file by analyzing the scan image file based on selection color information; a step(S430) which produces extraction image file indicated on the screen based on the pixel extraction information and indicates the extraction image file on the screen; a step(S440) selecting the arbitrary one point in the extraction image file; and a step(S450) obtaining the location information and the extracted color information of the selected point and indicating the information on the screen.
