Focused ultrasound researchers worldwide are making unprecedented progress in addressing the unmet need of providing life-extending treatment for patients with deadly brain tumors – glioblastoma multiforme (GBM).

GBM illustrationGBMs are aggressive and difficult to treat primary brain tumors. They are part of a class of tumors called astrocytomas, which come in four grades. Grades are determined by their appearance and characteristics under a microscope. GBM represents the highest-grade astrocytoma, Grade 4, and is also the most common of the astrocytomas.
