New Delhi: Doctors in India may soon have the facility to simulate the lung motion of a cancer patient to help deliver focused radiation in the upper abdomen or thoracic region.
Breathing motion is a hurdle for delivering focused radiation dose to the cancer tumour attached to upper abdomen and thoracic regions. The motion exposes an area larger than the tumour to radiation during cancer treatment, thus affecting tissues surrounding the targeted tumour. A focused radiation for a patient could be customised by simulating the lung movement of the particular patient and then orienting the delivery of the radiation so that it can be effective with minimal dosage. Before this is done on a human, its effectiveness needs to be checked on a robotic phantom.
