Micro-X is an Australian X-ray innovation company founded in 2011. The company has patented a way to create a carbon nanotube emitter for use in X-ray tubes. Carbon nanotubes are tiny cylindrical structures made entirely of carbon atoms, arranged in a hexagonal pattern. They are 100,000 times thinner than a human hair. Despite their size, they are incredibly strong and have unique electrical properties.[1]
Unlike conventional X-ray tubes, Micro-X's X-ray tube technology has a cold cathode, meaning that there is no need to use oil for cooling heated filaments. Instead, electrons are drawn directly from carbon nanotubes using a low-voltage electric field. This process, known as field emission, happens instantly and without heat. [2] Called Nano Electronic X-ray Technology, this way of generating X-rays is used in all Micro-X products.
In 2019, Micro-X successfully built and tested its first NEX Technology X-ray tube to 110kV.[3] Micro-X's first product to be launched and commercialised using NEX Technology was as OEM manufacturer for Carestream Health in 2017. [4] The Carestream DRX Revolution Nano Mobile X-ray System, designed and manufactured by Micro-X, marked the first commercialisation of carbon nanotube X-ray in healthcare. [5] [6] In 2020, Micro-X launched the Rover Mobile DR X-ray System and in 2022 the second generation Rover Plus was launched. [7]
In 2021, the United States Department of Homeland Security awarded Micro-X two contracts to develop a passenger self-screening solution and associated hardware for airport checkpoints.[8] The first contract to develop a Miniaturised Baggage CT Scanner is now complete, with the second contract extended through to airport testing of a module of 6 Passenger Checkpoints in 2025. [9]
Since then, the technology has been further developed to make X-ray tubes even smaller, with a series of mini tubes the size of a golfball to be used in a new portable CT Scanner for stroke diagnosis, funded by $8 million from the Australian Government's Medical Research Future Fund in partnership with the Australian Stroke Alliance.[10] In 2025 the United States Government research body ARPA-H announced Micro-X as one of the teams selected under the PARADIGM program to deliver advanced hospital-level care to rural areas. Micro-X is developing a hospital-grade full body CT scanner that is small enough to be deployed in a multi-functional, rugged electric vehicle platform. [11] [12]
