Researchers have revealed a new tool that allows precise targeting of radiotherapy for cancer radiation therapy.
Dr Corina Udrescu, from Centre Hospitalier Lyon Sud, said: "With this study we show that it is possible and very important to have a precise system that can give information at any time before or during treatment in terms of patient condition, technical issues and treatment duration, always maintaining the accuracy and safety of the irradiation."
The system tested by the French researchers was ExacTrac SV, which uses X-ray images acquired at any moment during treatment delivery to visualize tumors that move or change size and shape during radiotherapy treatment.
Dr Udrescu said: "The ultimate aim is to precisely irradiate the target, and protect the surrounding tissues from radiation as much as possible.
"Then we get the optimal ratio of tumor benefit to normal tissue damages."
French doctors presented the report at the 2nd European Lung Cancer Conference.
