TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a multi-person near-infrared spectroscopy brain function imaging device. BACKGROUND

[0002] Near-infrared spectroscopy brain function imaging (FNIRS) is a new type of brain function imaging technology. Using a multi-channel sensor composed of a near-infrared light and a transmitting probe-receiving probe, based on the neural-blood oxygen coupling mechanism, FNIRS can penetrate the skull, detect and image the changes of brain activity activation with high time resolution, and effectively visualize and quantitatively evaluate brain function.

[0003] In the existing near-infrared spectroscopy brain function imaging device, the commonly used solutions include but are not limited to setting a manual adjustment device to adjust the position of the measurement head to adapt to different head sizes and collect data from different angles.
