Dosimetric characteristics of cardiorespiratory motion during cardiac stereotactic body radiotherapy and dose gain from respiratory gating
Cardiorespiratory motion introduced dose uncertainties and interplay effects during CSBRT, leading to dose variations in the target and non-uniform dose distributions in the peripheral region surrounding the target, including cold and hot spots. The adoption of gating techniques substantially improved dose precision in CSBRT, effectively mitigating dose uncertainties associated with cardiorespiratory motion. Our findings highlight the importance of implementing respiratory motion management techniques to enhance the effectiveness and safety of CSBRT.
