An Assembled Prototype Multimaterial Three-Dimensional–Printed Model of the Neck for Computed Tomography– and Ultrasound-Guided Interventional ProceduresJavan, Ramin MD*; Cho, Alexander L. MS†Journal of Computer Assisted Tomography: November/December 2017 - Volume 41 - Issue 6 - p 941–948 doi: 10.1097/RCT.0000000000000630 Head and Neck Imaging Abstract Author Information A low-cost, semirealistic, multimaterial prototype phantom of the neck was developed for computed tomography– and ultrasound-guided interventions, using three-dimensional (3D) printing with a variety of materials as well as through molding techniques. This dual-modality phantom can be used by trainees for practicing procedures and can also serve as a prototype for developing more complex and realistic 3D-printed models, particularly with the continued development and advancement in multimaterial 3D printing technologies.
