title: MSI brain scan machines, the grandfather of biosensors.
abstract: We all know about MRIs. You hurt your knee and for $800 the doctor can have a close look inside, from the outside, and the resulting images can often prevent costly and painful knee surgery. A similar technological breakthrough has been achieved for use in diagnosing brain disorders such as epilepsy. Instead of electrode insertion into one's brain at a cost of $50,000, Biomagnetic Technologies' (BTi) totally passive Magnetic Source Imaging (MSI) machines can detect incredibly subtle differences, and provide the critical information for 10% of that cost.
