What is the purpose of a CT scan for cancer?

Before your treatment begins, your doctor will perform a CT scan, which will be transferred to the CyberKnife system, along with any MRI, CT or PET scans you may have had. This will help create a 3D image to pinpoint the specific size and location of your tumor. Your radiation oncologist will use this information to build a unique treatment plan for you, determining precisely how to target the tumor while keeping the surrounding area healthy.

What is the treatment for cancer?

Radiation therapy is a treatment option for many types of tumors throughout the body. Precise and accurate delivery of radiation to the tumor is key to killing cancerous cells while minimizing dose to healthy tissues. Accurate and precise delivery helps minimize irradiation of the healthy tissues surrounding tumors and potentially the risk of side effects, which may lead to better quality of life for the patient both during and after treatment.

How does tracking target movement help with radiation?

Tracking target movement — and synchronizing the delivery of radiation with that movement — helps to maximize treatment effectiveness, while minimizing dose to surrounding tissues, which can help reduce the incidence of side effects.

You do not need to be present during this step in the process.

What imaging is used to determine tumor size?

Scanning. Prior to treatment with the CyberKnife System, you will undergo imaging procedures to determine the size, shape and location of the tumor.
