MARKERLESS SURFACE TRACKING
FOR 4D CT RECONSTRUCTION.

A REVOLUTION IN RADIATION THERAPY

Tracks the 3D surface of a patient in real time without the need to apply external markers or any other physical device to the patient.

GateCT® tracks the 3D surface of a patient during 4DCT data acquisition. The system is synchronised with the CT scanner* and facilitates retrospective 4D CT reconstruction. Real time respiratory tracking enables prospective gated capture of CT data.

KEY FEATURES

• No markers are required
• Intuitive and easy to use
• 3D points or regions may be tracked anywhere on the patient’s surface
• All tracked data are calibrated precisely to the isocentre
• Tracking points may be determined automatically from a previous session
• Automatic detection of patient movement
• Automatic detection of abnormal breathing
• Low tracking latency
• Full surface data may be recorded in real time
