Functional Near Infrared Spectroscopy Device

We are currently looking to purchase a high-density functional near-infrared spectroscopy (fNIRS) device capable of diffuse optical tomography (DOT). We are looking for a device with a relatively portable form factor, so this is likely to be LED-based rather than laser optics. Accessibility and usability are a key consideration as the device may be used by students to conduct research. The device will primarily be used to assess activity in the prefrontal cortex of adults, but preference would be for a device that...
