Millions of people around the world suffer from brain illnesses which can be surgically treated such as hydrocephalus, infections, trauma, congenital malformations, epilepsy, brain tumors, and strokes. Advances in brain imaging have radically changed brain surgery in high-income countries and greatly improved patient outcomes. CT and MRI imaging allow three-dimensional visualization of individual patient anatomy, which is used in pre-surgical planning and to guide intraoperative steps during surgery. This brain imaging is linked to the surgical field through neuronavigation, giving neurosurgeons tools to perform more accurate surgeries. Yet, the prohibitively high costs associated with these technologies means these advances are still inaccessible for many populations outside of high-income countries.
