As an inspection method, new technology using 米-focused digital radiography is nowadays increasingly used in welding or fabrication industry. Compared to film based radiography, digital image can be acquired with high time efficiency and less radiation. However, noises can easily occur due to the system complexity, parameters sensitivity and environmental effect which can indicate low quality image and can result in difficulty for interpretation. Therefore, a need of an application tool which can improve, analyze and record the image is becoming an urgent task. In this research, an interactive and user-friendly application tool was developed containing important components which can be needed by interpreter or operator to analyze the defects and to record the results. This tool is divided into three important parts, namely: Image Processing Method (IPM), Image Quality Measurement (IQM) method and Radiographic Inspection Report (RIR). This application tool was written by using MATLAB＊s image processing tool which is further followed by a compilation process using GUIDE toolbox in MATLAB to build a WINDOWS stand-alone application which allows to be executed at any computer without the installation of MATLAB.
