Each step in the radiation treatment process, from CT to treatment delivery needs to be precise, ensuring the optimal treatment is achieved. In this debate we will focus on this precision, discussing if we have found the highest level of precision in radiation treatment. Topics for debate will include: -Modern planning and delivery systems have optimised target coverage. -Online Cone Beam CT/MR guidance has maximised precision in the preparation of the radiation therapy treatment -MR/CT imaging during radiotherapy delivery has optimised the precision and accuracy of radiation treatment delivery -The precision of highly conformal treatment techniques has resulted in improved clinical outcomes with reduced radiotherapy related side effects.
