The Gamma Knife Icon: Transforming Intracranial Radiation Treatments at UMMC.

Gamma Knife Icon is the latest version of the Gamma Knife - a stereotactic radiosurgery instrument known for its accuracy and efficiency in treating disorders and lesions of the brain. As an alternative to surgery the Icon device enables the treatment of patients immobilized not only in a traditional frame but also in a customized "face mask." Mask-based treatments are convenient and permit delivery of multifraction treatments that are suitable for larger lesions (>3cm/10cc) and lesions abutting critical brain structures, which would otherwise be unsuited for single-fraction treatment. Also, on-board cone beam CT capability and infra-red camera incorporation increase confidence in the precision of treatment deliver): The Icon increases the flexibility of the treatment process while ensuring the same level of daily accuracy. In this article, we discuss the unique capabilities of the Icon that make it a complete intracranial stereotactic radiation treatment solution and share our experience with its use at the University of Mississippi Medical Center (UMMC) over the past two years.
