Chasing RF Ghosts Across the Hospital Airwaves
When cardiac monitors flash false alarms at 2:14 a.m., an HTM specialist tracks rogue frequencies across the alley.
Imaging, networks and what's next
The Signal
The Signal covers the machines with physics in them and the devices with IP addresses: MRI and CT, monitors on the network, and the future the field is already servicing. Curious about new tools, allergic to hype.
The beat: Imaging systems, networked devices, cybersecurity, data, AI, home care and the technology arriving in hospitals next.
