Respiratory Gating
Key Features
Respiratory Gating
• is capturing slow moving anatomical structures such
as lung lesions during respiration up to a respiration
cycle time of 10sec by low pitch spiral.
• helps the radio-oncologists in selecting the appropri-
ate phase of the respiratory cycle in order to plan a
treatment more accurately.
• helps visualizing the tumor excursion for a better
understanding of the target volume using InSpace
4D.
• results in a more accurate description of the ROI and
• is considering tumor motion into the PTV (planned
target volume).
Respiration Monitoring
• Accurate determination of respiratory motion
• Respiration change recognition (cough, sneeze,
movement)
• Support for monitoring of free-breathing and breath
hold respiration protocols
