April 08, 2010 - New technologies enable accurate, non-invasive lung tumor treatment without additional intra-fraction radiation imaging -Elekta has introduced an advanced solution for treating lung tumors that enables doctors to visually confirm the tumor’s position during the breathing cycle. This new technology treats the lesion with a continuous radiation beam, increasing therapy accuracy while using less imaging radiation during treatment delivery.
Lung tumors have been among the most challenging radiation therapy targets because the patient’s breathing causes tumors to move. New research has shown that the lung tumor shifts position from day to day during the course of treatment (baseline shift).1 Doctors often have had to use external skin surface markers or implanted markers to estimate lung tumor position during the breathing cycle and then apply the beam only during certain points in the patient’s respiration. These strategies require complex, time-consuming planning and delivery, and prolong treatment with an inefficient stop-start (i.e., gated) beam delivery.
