1.0 SCOPEThis document presides over the use of Array’s 2905 laser film digitization.Hardware and software criterion are clearly defined and specified in order to standardize and maintain good quality control of digitized radiographic image.This document only covers on the process procedure to digitize conventional radiograph films.Hence, this document does not include any guidance or specifications with regard to the evaluation of the digitized images for acceptance or rejection to any criteria pertaining to flaw sizing, defect recognition or any other structural integrity evaluation of the subject or part imaged.NOTE: Other systems that exhibit equivalent capabilities enlisted in this document may be used upon consent from a Malaysia Nuclear Agency personnel who is qualified, and certified in the film digitization process.

2.0 PROCEDURE GUIDELINES FORTHE DIGITIZATION OF RADIOGRAPHSThis procedure provides guidelines to fully perform digitization radiograph process in accordance to industrial standard.

3.0 PURPOSEThe aim of this procedure is to clarify the essential items required for preparing, handling, digitizing and storing industrial radiographs. This procedure shall also define quality control standards that will allow for uniformity of data integrity and image quality. This is done in an effort to allow for the digitization of existing radiographs for subsequent interpretation and long term storage.
