Portable diffusion correlation spectroscopy device for tissue blood flow monitoring based on STM32 microcontroller
Traditionally, diffusion correlation spectroscopy (DCS) calculates blood flow (BF) by measuring the temporal intensity fluctuations of multiple scattered light by DCS devices that fit all the requirements, which consists of a source-detector pair, a data acquisition card, and a host computer. In this paper, a portable DCS device based on STM32 microcontroller unit (MCU) is proposed in order to solve the drawbacks of traditional DCS devices, which are costly and bulky. Arterial occlusion experiment was established by monitoring the subject's arm blood flow changes based on two devices, simultaneously. The experimental results indicated that excellent agreement of blood flow changes measured and intensity auto-correlation function detected by portable DCS device and traditional DCS device.
