Basic Treatment Planning

Why use IMRT?

• Improve conformity with target dose, e.g. prostate cases with hip prosthesis

• Reduce irradiation of normal tissues e.g. parotid glands and spinal cord in head and neck cases

• Facilitate dose escalation e.g. prostate and head and neck cases

• Treat concave structures to a high dose, for example, nasopharyngeal cases
