A design process for a 3D printed patient-specific applicator for HDR brachytherapy of the orbit.

ABSTRACT:

Background

This report describes a process for designing a 3D printed patient-specific applicator for HDR brachytherapy of the orbit.

Case presentation

A 34-year-old man with recurrent melanoma of the orbit was referred for consideration of re-irradiation. An applicator for HDR brachytherapy was designed based on the computed tomography (CT) of patient anatomy. The body contour was used to generate an applicator with a flush fit against the patient's skin while the planning target volume (PTV) was used to devise channels that allow for access and coverage of the tumor bed. An end-to-end dosimetric test was devised to determine feasibility for clinical use. The applicator was designed to conform to the volume and contours inside the orbital cavity. Support wings placed flush
