Image guided radiotherapy
This technique permits the patient’s position on the treatment table to be checked each day and adjustments made before administering radiation. An x-ray with an amorphous silicon detector panel provides CT images of the patient. These images allow the patient’s position on the table to be adjusted and the evolution of the tumor to be monitored during treatment, adapting the treatment plan as necessary. This is known as adaptive radiotherapy.
Advantages: Useful for all types of treatment, especially in the case of cranial and extracranial (stereotactic body radiation therapy) radiosurgery, where the tumor can be localized to within a millimeter prior to each treatment session.
