Performance assessment of the NIRS-based medical system of evaluating therapeutic effect

Near-infrared Spectroscopy (NIRS) is a portable, noninvasive detection method in many medical applications. With the ability to measure hemodynamics, NIRS has been applied in disease diagnosis, patient monitoring and therapeutic effect evaluation. To quantitatively assess the therapeutic effect, we developed a NIRS-based efficacy evaluation system. This study mainly focused on the performance assessment of the system. A series of experiments were performed on the stability, sensitivity, response time, and clinical characteristics. In conclusion, the efficacy evaluation system realized real-time and continuous monitoring before and after therapy.
