2. ECE-1
PROJECT GOAL:
To develop a “wearable” imaging system that will be used in medical diagnosis & monitoring, learning assessment and other applications where blood flow changes are used to assess function.
The system incorporates
stimulus,
data acquisition,
signal processing, and
data transmission
to replace the desktop instrumentation currently in use.
