Construction of an Anthropomorphic Phantom for Use in Evaluating Pediatric Airway Digital Tomosynthesis Protocols

Figure 4

View of the AE components and how they fit within the middle slab of the phantom. Clockwise from top left: multiple copies of two sizes were printed. The linear dimensions are given for the X-ray image with a centimeter scale appearing for comparison. The angle at the carina between the right and the left mainstem bronchi is 90 degrees. The tubes are continuously hollow and sealed airtight before being inserted and imaged as part of the phantom. A side view showing how the airway fits in the middle slab. A 1 mm gap between the LE component and the container (lower left image) allows for water to uniformly fill any space not occupied by the LE or AE substitutes. An AP view.
