This resulted in inaccurate dose prediction especially against radiation from axial direction when calculating dose distribution. This research using object interpolation on 19 organs suggest in ICRP 60. The resolution in head and necks resolution get improved from 0.613 mm × 0.613 mm × 1.98 mm to 0.613 mm × 0.613 mm × 0.66 mm and 0.613 mm × 0.613 mm × 3.96 mm to 0.613 mm × 0.613 mm × 0.66 mm below neck. We used coronal view and sagittal view to check the tissues/organs continuity and appearance. The 3-dimensional view checks for artifact. The result of this research shows, in coronal and sagittal view, continuity improved in tissues edges especially in small organ. It becomes smoother and more continue after object interpolation. Comparison of total tissue volume and quality shows not much differences before/after interpolation in large tissue/organ, however in small tissues the differences is approximate to 10%. Resolution enhancement is successfully done in this research using object interpolation in CRAF phantoms. T. C. Chao 趙自強 2012 學位論文 ; thesis 70 |
