简要总结

Accuracy Of CBCT affected by many factors. On of the most factors the affect the image quality is voxel size. Larger voxel size give a higher accuracy of the images but with higher radiation dose.

The study is to assist the accuracy of surgical guides designed from CBCT with different voxel sizes .

详细描述

Accuracy Of CBCT affected by many factors. On of the most factors the affect the image quality is voxel size. Larger voxel size give a higher accuracy of the images but with higher radiation dose.

The study is to assist the accuracy of surgical guides designed from CBCT with different voxel sizes (voxel size 0.4mm & 0.2mm)
