Embodiment

[0112] attached Figure 13 For the overall shape of the spliced ​​near-infrared spectrum brain function imaging helmet, it covers the human head.

[0113] attached Figure 14 It is the rendering of the near-infrared spectral brain functional imaging helmet worn on the subject's head. The fiber optic probe is inserted into the probe position in the figure.

[0114] In order to fix the laser probe inserted into the probe position of the near-infrared spectrum brain functional imaging helmet, a Velcro with a width of about 1.5 cm is pasted on the lower edge of the helmet. Figure 14 shown. From attached Figure 14 It can be seen that the near-infrared spectrum brain functional imaging helmet designed in the present invention can cover most of the cerebral cortex area, and can be used for detection of large-area cerebral cortex functional activities.

Abstract

A near infrared cerebral function imaging helmet is composed of 9 orthopentagons with side length of 3cm and 23 orthohexagons with side length of 3cm. 20 laser probes, a laser light source probe and a laser receiving probe are arranged in the area covered by each orthopentagon. 19 laser probes, a laser light source probe and a laser receiving probe are arranged in the area covered by each orthohexagon.

Description

technical field [0001] The invention relates to the fields of medical equipment and medical imaging, in particular to a near-infrared spectrum brain function imaging helmet. Background technique [0002] Near-infrared spectral brain functional imaging is a brain functional imaging method developed since the 1970s that uses the good penetration of near-infrared light into brain tissue to detect the functional activities of the cerebral cortex. [0003] In the near-infrared spectral brain functional imaging system, the near-infrared light enters the brain tissue through the laser light source probe (abbreviated as S), and the outgoing light after passing through the brain tissue is detected by the laser receiving probe (abbreviated as D). The propagation path of near-infrared light in brain tissue is shown in the attached figure 1 shown. attached figure 1 In the above, the laser light source probe (S) and the laser receiving probe (D) are placed close to the scalp. When the...
