Embodiments herein provide a non-invasive tracking system that accurately predicts the location of tumors, such as lung tumors, in real time, while allowing patients to breathe naturally. This is accomplished by using Electrical Impedance Tomography (EIT), in conjunction with spirometry, strain gauge and infrared sensors, and by using sophisticated patient-specific mathematical models that incorporate the dynamics of tumor motion. With the direction and speed of lung tumor movement successfully tracked, radiation may be effectively delivered to the lung tumor and not to the surrounding healthy tissue, thus increased radiation dosage may be directed to improving local tumor control without compromising functional parenchyma.
