Dr. Descovich specializes in the physics of stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT). SRS and SBRT are advanced modalities of radiation therapy, enabling high targeting accuracy. The CyberKnife system is a medical device entirely dedicated to SRS and SBRT treatments. It combines a sophisticated tracking system with a robotically mounted linear accelerator capable of delivering radiation from hundreds of different directions while synchronizing with respiratory induced target motion. Radiosurgery treatments are complex and require a team of specialized experts. Dr. Descovich has been the lead physicist responsible for the CyberKnife program since the installation of the CyberKnife VSI at Helen Diller Family Comprehensive Cancer Center in 2010.
