About Us

The Genesis of GT Medical Technologies and GammaTile® Therapy

For decades, clinicians have sought better treatment options for patients with brain tumors that would effectively target tumor cells while preserving eloquent tissue.
Driven to overcome the limitations of current treatments and raise the standard of care, a group of brain tumor specialists joined forces to address this critical, unmet need. Together with medical device experts, they developed GammaTile Therapy, Surgically Targeted Radiation Therapy (STaRT) for recurrent intracranial neoplasms.
