The effect of object to film distance (OFD) to industrial radiography image

Abstract

The object to film distance (OFD) to image when using radiography testing were discussed and whether the image can be improved by IIP Console Software in Digital Radiography method were studied. The artificial defect of wooden block with different size was used as the test sample in this study. The object to film distance (OFD) to the image were capture by using XRS-4 model X-ray source and flat panel detector. The image was analyzing by using IIP Console Software. The obtained results show that irregular surface has better and sharper image compare to flat surface to 9 mm hole wooden block. Meanwhile for 15 mm hole, flat wooden block show better and sharper image compare to irregular surface
