About the Surgery
Novalis is a state-of-the-art treatment device for patients undergoing stereotactic radiosurgery or fractionated stereotactic radiotherapy. Stereotactic radiosurgery is applied in a single session with a high dose of radiation. Fractionated stereotactic radiotherapy is administered in a series of treatment sessions over a specified period of time.
With Novalis, the radiation beams are shaped to match the exact contour of the tumor or lesion so that even irregularly shaped tumors or lesions can receive doses of radiation totally consistent with that prescribed. Sophisticated software calculates the ideal access points to the tumor or lesion and defines the treatment plan.
During treatment, Novalis steadily moves around the patient's body so that the radiation penetrates the tumor or lesion from different angles. While the tumor or lesion receives the full dose of radiation, the surrounding healthy tissue only receives a small percentage of the radiation, which reduces potential damage to delicate structures such as the brainstem or spinal cord.
Novalis was first implemented for the treatment of brain tumors or lesions, where pinpoint precision is required to focus radiation treatment on tumors or lesions close to critical structures within the brain. Now, experts are taking advantage of the accuracy of Novalis to treat other areas of the body, such as the lung, liver, prostate and spine, to improve and increase the range of a patient's available treatment options.
