Computed Tomography plays an important role in treatment planning of tumours through its ability in localization of tumour and normal tissue most accurately. It presents the true cross-sectional picture of anatomy in terms of varying CT numbers. It helps through the treatment planning system in applying inhomogeniety corrections to dosage calculations. CT also helps to obtain a three dimensional representation of the tumour volume which helps in reducing geometrical miss of the tumour during radiation therapy. Various technical and procedural requirements and clinical considerations of the role of CT in treatment planning are discussed.
