Image Guided Radiation Therapy (IGRT with CyberKnife and TomoTherapy) – Dallas, TX

27 Treatments ( View All )


Image guided radiation therapy (IGRT) uses advanced scanning before and during every treatment to create a unique treatment plan for every patient. Computed tomography (CT) scans are used for treatment planning along with the system's advanced software system to determine where the radiation should be aimed to provide a safe dose of radiation to the tumor while minimizing radiation to surrounding healthy tissue. At Premier Cancer Centers in Dallas, our board-certified radiation oncologist uses both the CyberKnife and TomoTherapy systems to perform external beam radiation therapy (EBRT) with image guidance. The CyberKnife system uses a computed tomography (CT) scan for treatment planning and then takes kV X-ray images every 15 seconds during the treatment to adjust the accuracy of the radiation. The TomoTherapy uses a low-dose CT scan for treatment planning and also during the treatment to adjust for patient or tumor movement.


The image guidance used during radiation therapy with the CyberKnife and TomoTherapy also customized treatment planning for every patient to apply accurate, high-doses of radiation to the tumor with limited radiation to the healthy tissue surrounding the treated area. This limits the side effects the patient experiences during their treatment and prevents damage to healthy cells. The image guidance used during the CyberKnife treatment adjusts during the treatment based on movements of either the patient or the tumor to maintain an accurate treatment.
