Respiratory Gating

Respiratory Gating tracks a patient’s breathing during radiation therapy to precisely target the tumour and reduce the potential impact of radiation.


During radiation therapy, a patient’s breathing can cause respiratory movements of the tumour location and some vital organs, which may lead to radiation to surrounding tissue and subsequent impacts such as radiation pneumonitis and radiation hepatitis.

Respiratory Gating can achieve improved results by tracking the patient’s breathing rate, precisely targeting the tumour and reducing the potential impact of radiation.

This technique is primarily used for the treatment of lung, liver, breast and abdominal tumours and other cancers that are strongly affected by breathing.
