REAL TIME, MARKERLESS, RESPIRATORY GATING

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.

GateRT® tracks respiratory motion in real time during radiation delivery or diagnostic imaging. The system monitors signals derived from the 3D surface of the patient. Suitable gating thresholds are determined by the user and set within the software. These are used to gate the radiation beam during treatment* or imaging*.

WORKFLOW AND BENEFITS

• Acquire reference surface and select optimal tracking points. To ensure reproducibility, these can be imported from a previously captured reference surface
• As determined by the 4D treatment plan, suitable gatnig and patient motion thresholds are set
• GateRT® supports both amplitude and phase based gating protocols
• Start tracking. The beam is gated* according to user defined gating thresholds
• GateRT® also monitors patient movement and abnormal breathing. If either of these exceeds a pre-set tolerance, the beam is held automatically*

*Full details of supported interfaces are provided in third party interface statement.
