Dynamic 4D CT (D4DCT) can replace bronchography in the assessment of tracheobronchomalacia (TBM) but setting up a new D4DCT service for infants with TBM poses unique challenges due to their venerability. Simulation prior to implementation is essential as D4DCT involves continuous volumetric CT scanning through the breathing cycle, potentially delivering high radiation doses. Radiation dose, gantry rotation and scan dynamics can be customized. Our purpose is to describe the development and implementation of CT dynamic airway protocol using a 3D printed <i>Infant Dynamic Airway Phantom</i> (phantom) for simulation of D4DCT in tachnypnoea and collapsible airways, thereby validating image quality and estimating radiation dose prior to clinical implementation.

Successful bronchoscope handling requires the skill to orient bronchoscope position and direction in response to the intraluminal view provided by the bronchoscope camera. Additional challenges for pediatric physicians are smaller airways and the physiologically higher breathing frequency and airway collapsibility in babies and toddlers. We aimed to create a set of anatomically accurate 3D printed pediatric static and dynamic airway models that can be further used to teach and train residents/fellows in bronchoscopy and foreign body removal.

3D printing technology presents a unique opportunity for the creation of custom phantoms for training and simulation for pediatric interventional procedures that are complex and/or uncommonly performed. The purpose of this study was to describe the elements of designing a 3D phantom for simulation of pediatric abdominal intra -vascular procedures. Read More
