Airport CT security scanner animation: revealing baggage flow and radiation containment
A technical 3D animation showing how coordinated conveyor speeds, luggage spacing and protective curtains work together inside an airport CT baggage-screening system.
CT Scanner Case Study Video
Project overview
Airport CT security scanners use computed tomography to generate detailed three-dimensional images of carry-on luggage. These images allow screening systems and airport operators to examine objects from multiple angles and improve automated threat detection.
However, the advanced scanning process also creates a difficult engineering and communication challenge: how can the scanner maintain radiation containment while processing a continuous flow of baggage efficiently?
Pentaract Studio created a technical 3D animation to explain the problem, reveal the internal system and demonstrate how controlled conveyor speeds can manage baggage spacing through the scanner.
The objective was to transform a complex interaction between X-rays, protective curtains, moving bags and multiple conveyor sections into a visual story that airport operators, technical teams and non-technical decision-makers could understand.

The technical communication challenge
Unlike a conventional baggage scanner, a CT security system produces detailed volumetric images that allow objects inside luggage to be inspected in three dimensions.
The more intensive X-ray process introduces an important containment requirement around the scanner tunnel.
Protective radiation curtains are positioned at the entry and exit of the system. When fully lowered, these curtains help contain X-rays within the scanning tunnel. During continuous operation, however, luggage passing through the scanner can push the curtains away from their closed position.
If bags follow one another without sufficient spacing, several curtains may remain partially open at the same time. This can create a path through which radiation escapes around the entry or exit of the tunnel.
Because the leakage changes as bags and curtains move, the issue cannot always be communicated clearly through static diagrams or measurements.
The animation needed to make this dynamic behavior visible.
Visualizing dynamic radiation leakage
The first part of the film establishes how radiation containment works under ideal conditions.
With no luggage beneath it, each protective curtain can return to its fully lowered position. The curtains create successive barriers between the scanning area and the tunnel opening.
The animation then introduces a continuous stream of bags.
As luggage moves through the scanner:
-
The first bag lifts the entry curtain.
-
The following bag reaches the next curtain before the first curtain has completely lowered.
-
Several curtains can remain displaced simultaneously.
-
The open path allows radiation to travel farther toward the tunnel entrance or exit.
Making the X-ray field visible allows viewers to understand an otherwise invisible safety consideration.
The sequence clearly connects three variables:
-
The distance between bags
-
The position of the protective curtains
-
The resulting containment of radiation inside the scanner
This gives the audience a visual explanation of why baggage spacing matters—not only for movement through the machine, but also for the performance of its radiation-containment system.
The throughput and system-footprint trade-off
One possible way to create safer spacing is to increase the distance between every bag before it enters the scanner.
Larger gaps give each protective curtain more time to fall back into position before the next bag arrives. However, maintaining large gaps throughout the complete scanning process can create another problem.
It may reduce the number of bags processed within a given period and require a longer conveyor tunnel to accommodate the additional spacing.
For busy airport checkpoints, this introduces a difficult engineering balance:
-
Radiation containment must remain controlled.
-
Baggage must continue moving efficiently.
-
The scanner should not require an unnecessarily long footprint.
-
Passenger-screening operations should avoid preventable delays.
The film presents this challenge before introducing the scanner’s coordinated conveyor arrangement. This problem–solution structure helps the audience understand why the internal mechanism matters commercially.
Explaining the coordinated conveyor system
The system uses multiple conveyor sections operating at different controlled speeds.
Instead of preserving the same large distance between bags throughout the entire scanner, the conveyors adjust the spacing only where it is needed.
The animation separates the process into three clear stages.
1. Creating space at the scanner entrance
The conveyor sections located beneath the entry curtains move the bags forward at a higher speed.
This temporary acceleration increases the distance between consecutive pieces of luggage. The larger gap gives the curtains time to lower between bags, helping restore the containment barrier at the tunnel entrance.
The spacing is created precisely where the protective curtains require it.
2. Reducing the gap through the scanning area
After passing the entry curtains, the bag reaches the central scanning conveyor.
This section operates at a slower controlled speed. The reduced speed allows the following bag to move closer again, preventing unnecessarily large gaps from continuing through the complete scanning area.
The film visualizes this change by following the distance between two bags as they move from the faster entry section to the slower scanning belt.
This demonstrates how the system can use available scanner space more efficiently while maintaining an organized flow of luggage.
3. Recreating the gap at the scanner exit
As the bag approaches the end of the scanning tunnel, the exit conveyor increases its speed.
The acceleration creates another temporary gap between bags before they pass beneath the exit curtains.
This gives the protective curtains an opportunity to return to their lowered position, helping contain radiation around the scanner exit.
The sequence completes a coordinated cycle:
Increase spacing → scan efficiently → increase spacing again
By showing the complete journey of the luggage, the animation explains how the different conveyor zones work together as one system.
Making the internal mechanism understandable
The challenge was not simply to animate bags moving through a scanner. The film needed to communicate the relationship between several events occurring simultaneously.
Technical 3D animation made it possible to:
-
Open the scanner through transparent and cutaway views
-
Reveal conveyor sections normally hidden beneath the machine
-
Visualize radiation that cannot be seen by the human eye
-
Show when individual curtains are open or fully lowered
-
Track the changing distance between consecutive bags
-
Compare different conveyor speeds
-
Slow down important mechanical moments
-
Present the process from the clearest possible camera angle
Each visual element was introduced only when it supported the explanation.
The animation moved progressively from the external product to the internal problem, then from the problem to the coordinated engineering solution.
Technical accuracy with cinematic clarity
Technical product animation must remain precise without overwhelming the audience.
The film uses controlled camera movement, simplified visual hierarchy and focused technical graphics to guide attention toward the details that matter.
Complex information is introduced in stages:
-
Establish the airport CT scanning system.
-
Explain the role of the protective curtains.
-
Show the effect of continuous baggage movement.
-
Reveal the radiation-containment challenge.
-
Introduce the different conveyor zones.
-
Follow the spacing changes through the scanner.
-
Connect the engineering solution to the product benefit.
This structure allows technical teams to recognize the mechanism while helping non-technical decision-makers understand its purpose.
Designed for technical sales and product communication

Shorter edits, silent loops and presentation-ready versions can also be produced from the primary animation for different platforms and audiences.
The final result
The finished technical animation turns a hidden interaction between baggage, conveyors, protective curtains and X-ray containment into a clear visual product story.
It demonstrates how carefully planned 3D animation can communicate more than the appearance of an industrial product. It can reveal the engineering logic behind the product and help customers understand why its design matters.
By combining cutaway visualization, controlled movement and a structured problem–solution narrative, the film makes a complex airport-security system easier to understand, present and sell.
