The Advent of Wireless X-Ray

The Advent of Wireless X-Ray

Wireless X-Ray uses radio frequency instead of sensors and traditional photographic film to see through walls, clothing and the human body. The device digitally transfers and produces enhanced images of a person it detects. Digital radiology serves as an enormous technological advancement in medical imaging over the years. Researchers from MIT’s Computer Science and Artificial Intelligence Lab (Csail) has proved this with Wireless X-Ray. Its new system called RF-Capture emits wireless signals like Wi-Fi and picks up how these signals are reflected on human body. MIT’s computer scientists used radio frequency (RF) wireless electromagnetic waves to exactly track a 3D position of a person. The development started in 2013 and aims to change the way human behaviors are being tracked. The advancement has patched the excitement of medical practitioners and professional IT services Australia.

How Radio Frequency Works

The device transmits wireless signals that traverse through the wall and show off a human body back to the device. The emitted radiation is approximately 1/10,000 which is an amount given off by a standard mobile. The device intelligently captures and analyses the reflections from its subject. The equipment can then stitch the different reflections of a person at different times to provide the person’s single silhouette. Out of the analysed image people can easily track a 3D human movement and see what they are doing.

Medical and Household Help

Every year, there are 2.5 million elderly treated in emergency rooms because of falls. Research also shows that 9 out of 10 falls occurs at home when they are alone. Prof. Dina Katabi, Director of Wireless@MT Center, said that they are working on turning this technology into an in-home device. MIT developed “Emerald” which serves as a modern detection for families and caregivers. Emerald doesn’t need the patient to wear any sensor, it can track the 3D motion of a person’s body even if behind walls. The device will alert the family or caregiver through phone or email if there is a fall, while automatically contacting an ambulance. Emerald is intelligently designed and can display changes in mobility over time. This can help predict and prevent falls by identifying a person’s daily movement. It can also detect any changes which signals that the person has symptoms of being unwell.

Societal Impact

Wireless X-Ray progressively influences our life and the society. This technology can also be used in movies as it will capture motions mapping the actors’ movements to create a computer-generated characters. This development is useful to virtual reality and game developers. They can map the users’ movements using haptic controllers in a virtual environment. Law enforcement can easily scan whole blocks, buildings and houses of people and find illegal activity for those anonymous tips. It’s even easier for firefighters to check what part of the vicinity a person is trapped. They can even figure out if people are trapped in a burning edifice without putting their lives at risk by searching manually.


Wireless X-Ray is recognised as a spot-on solution to the medical and digital industries’ critical task requirements. IT services Australia stated that the technology offers vast potential and development. This can help enhance medical research and operations while minimising false alarms with a person’s medical condition. The device is also a crime fighting tool because of its capability of seeing through walls and clothing. Wireless X-ray is one great IT development example which shows that technologies are essential to humanity and society.
