To present and discuss: •The scientific basis of IMRT/VMAT and highly conformal radiation techniques •The technical aspects of treatment preparation and treatment delivery •Dose calculation and the quality assurance process •Inverse planning optimisation and its practical implementation •The latest developments in IMRT/VMAT irradiation modalities •The clinical aspects of IMRT/VMAT, including clinical outcomes, site-specific issues, normal tissue tolerance and emerging indications. •The relationship between IMRT/VMAT and other advanced radiotherapy techniques (e.g., IGRT, SBRT and adaptive radiotherapy). •Re-irradiation challenges: image registration, dose accumulation, constraints. •Most impactful papers on Highly Conformal Techniques
