Abstract Text

Radiotherapy treatment delivery to targets in the lung is complicated by organ motion associated with breathing.

Many strategies exist to assist in reducing this impact including immobilisation, coached breathing techniques and image guidance.

This session will cover target delineation and lung radiotherapy treatment delivery using 4DCT, free breathing, breath-hold (inspiration/expiration), kV, fluoroscopy, cone-beam CT and surface guidance. The impact of each technique and how a combination approach may be needed in complex cases will be highlighted.

A review of complex cases will be discussed and IGART used.
