| Abstract | ||
| This study compared the accuracy of linear cephalometric measurements between the com-pressed and non-compressed digital cephalometric images. Materials and Methods: The adult sample consisted of (60) Iraqi subjects (30 females and 30 males) with age ranged 18 – 25 years old, the sam-ples satisfied the criteria of this study. Eight linear cephalometric measurements were recorded from lateral digital cephalometric radiographs, the ACDsee photo manger software used to compress and resaved the original images in 80% and 60% from their original size. The data were analyzed using descriptive statistic and ANOVA & Duncan test. Results: No significant differences were found be-tween the accuracy of the compressed and non-compressed digital cephalometric measurements. Con-clusions: The results of this study indicated that image compression up to 60% of their original size will not effect on the accuracy of routine cephalometric analysis and reduce the size of image storage and facilitates the easier and faster image transmission. | ||
