SUMMARY
The use of CT to design and fabricate a custom radi-ation carrier for a patient with rhabdomyosarcoma of thenasopharynx has been described. Previous methods ofimpression making would have been more expensiveand invasive and would have required an additional ap-pointment. With the CT method, the patient had to beavailable only for a conventional thin-cut scan; no fittingappointments or anesthesia were necessary. The proce-dure allowed for precise fabrication of a carrier on thebasis of an accurate representation of the undistortedarea.
