Distortion is an uneven magnification on different parts of the same object. Research on
geometric distortion has been done on radiographic images. The position of the object
used is 0 °, 30 °, 45 ° and 90 °. The research was conducted on Radiology unit at Dumai
City Hospital area. From the results of this study found that there is distortion at
positions 30 ° and 45 ° and magnification occurs in each image. Distortion can also
affect the density of the radiographic image, from the results of the test using
densitometer then found each image with a close Focus Film Distancefound low density
but if the Focus Film distance too far density can also be low.
