Computed Tomography machines, more commonly known as CT machines, are a fairly new concept to passenger and hand baggage screening at airports globally. Due to their unique capabilities, they are rapidly being rolled out at airports to improve the overall checkpoint experience. CT machines have been used in Hold Baggage Screening for a number of years and now their transition to the checkpoint is a promising step for both the airport and the passenger.
Many airports are trialling CT machines but some countries such as the US, Netherlands, Australia, and the UK are actually mandating the use of the machines.
Melbourne Airport has been rolling out CT scanners over the last 6 months. With this implementation the airport has been able to:
CT machines bring a notably large change to carry-on baggage screening. Airports need to do a few things in order to ensure the implementation of CT is seamless and reaps the intended benefits:
To support airports implementing CT machines, ACI’s Smart Security programme has released an Implementation Guide covering the whole cycle from procurement to implementation.
With a doubling of passengers expected by 2037, there is a need to implement improved innovative technology for better security, operational efficiency, and the customer experience. There is no one size fits all to security innovation, however. Airports should always introduce measures that make the most operational and business sense for their particular situation, in cooperation with their authorities and stakeholders.
