Drexel University Optical Imaging Research Group Junior/Senior Clinic ECE-1 Development of FPGA-based fNIR (functional Near InfraRed) Spectroscopy for Brain Imaging Applications L. Head ECE – Rowan University with Drexel University Optical Imaging Research Group Fall 2007

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.

X ECE-1 Making the transition from: A desk-top, PC-based system To a single headband system with on-board stimulus, detection, processing, and transmission X BATTERY LED DETECTOR TX FPGA ADC

ECE-1 Sensor development – modular parts from molded rubber Tasks: Develop Solidworks models for new applications Create molds for modular sensors Investigate material properties for optimal sensor flexibility and interface with targeted areas of body (forehead – arm) Develop attachment hardware that provides subject comfort and unrestricted motion
