Respiratory gating and tumor tracking are two promising motion-adaptive lung cancer treatments, minimizing incidence and severity of normal tissues and precisely delivering radiation dose to the tumor. Accurate respiration measurement is important in respiratory-gated radiotherapy. Conventional gating techniques are either invasive to the body or bring insufficient accuracy and discomfort to the patients...
Tumor tracking is important for radiotherapy treatment of lung cancer to deliver sufficient radiation dose without damaging the surrounding healthy lung tissue and causing severe side effects such as pneumonitis. However, conventional tumor tracking methods are either invasive to the patients or do not have sufficient accuracy. Radar physiological motion sensing provides a noninvasive and yet accurate...
Respiration-gated radiation therapy is a promising treatment modality that precisely delivers prescribed radiation dose to the lung tumor while minimizing the incidence and severity of normal tissue complications. Conventional gating techniques either rely on implanted fiducial markers or external surrogates such as markers placed on patients' abdomen. They are either invasive to the patients or do...
