| Research Abstract |
The aim of this study was to compare cone-beam CT guidance using gold markers and calcium phosphate markers and then to assess whether they are equivalent methods of determining isocenter corrections. Our study demonstrates that calcium phosphate markers of >= 2 cm3 has good compressive strength and good radiographic visibility both on planning CT and cone beam CT. This is an ideal marker which has no artifacts on CT images and might not migrate during treatment.
