Medical imaging devices are increasingly connected to hospital networks, making them susceptible to cyber attacks that can disrupt digital patient records.
A comprehensive risk analysis survey found that CT devices face the greatest risk of cyber attack due to their crucial role in acute care imaging.
Here are four ways cyber attacks can damage CT devices:
1. Disruption of the parameters' values used in the scanning protocols such as tampering with the radiation exposure levels.
2. Mechanical disruption of the CT device, such as changing the pitch.
3. Disruption of the tomography scan signals constructing the digital images.
4. Denial-of-Service attacks against the device.
