For Radiotherapy: Ct Anatomy

The circle of Willis, pituitary fossa, and ventricles.

Dedicated wide-bore CT scanners used with immobilization devices to replicate treatment positioning.

Parotid glands, spinal cord, brainstem, larynx, and mandible. CT Anatomy for Radiotherapy

Managing organ filling (e.g., bladder and rectum protocol) to ensure reproducible anatomy during daily treatments. 🛠️ Advanced Imaging Integration

Different clinicians may contour the same structure differently, driving the need for standardized atlas guidelines (e.g., RTOG/NRG guidelines). The circle of Willis, pituitary fossa, and ventricles

Femoral heads, iliac crests, and symphysis pubis.

Tolerance doses dictate the maximum radiation the target can receive. The circle of Willis

Sparing the parotid glands to prevent xerostomia (chronic dry mouth). 🫁 Thorax Key OARs: Lungs, heart, esophagus, and spinal cord. Anatomical Landmarks: Carina, aortic arch, and diaphragm.
