This webinar explores the 14-year journey of integrating the TomoTherapy® System into clinical workflows. From the first Hi-Art system in Thailand in 2012 to the Radixact® X9 System with kVCT and real-time tracking @ Chiang Mai University Hospital. It highlights the progression from basic to advanced techniques (e.g., CSI, head & neck, pelvis, breast, brain/SRS, lung, prostate, ART, TSI/TBI), key clinical/technical challenges, and practical solutions to optimize treatment planning, delivery, imaging, and quality assurance.
