The application provides a small animal sciatic nerve magnetic resonance coil and an imaging method, and the method comprises the following steps: filling a high-concentration sugar syrup solution at the bottom of the magnetic resonance coil and performing constant temperature control; placing a small animal in a prone position in the high-concentration sugar syrup solution and discharging air in the gap between the lower limbs and below the abdomen of the small animal; after performing magnetic resonance positioning scanning to determine the main sequence scanning range, starting the main sequence scanning, suppressing the flow tissue signal through a pre-pulse combination, exciting the tissue by using a radio frequency pulse with preset parameters, acquiring echo signals by combining a fast spin echo technology and filling K space, and obtaining scanning original data; performing preprocessing on the scanning original data and accurate segmentation of the sciatic nerve and spinal nerve to obtain a segmentation result; and completing three-dimensional model reconstruction, optimization and multi-modal fusion visualization based on the segmentation result to obtain an image scanning result. The application is suitable for small animals, is accurate in imaging, can effectively suppress various kinds of artifacts, and can be widely applied to sciatic nerve imaging scenarios of small animals.

This application relates to a brain-computer interface (BCI) control system and method. Its wireless power supply transmitter transmits energy through the skin at a frequency of 6.78MHz via magnetic resonance coupling to an implantable BCI controller (ICU) within the body. This allows the ICU to power an implantable brain signal acquisition unit (NRU) and an implantable spinal nerve stimulator (NSU) based on the received energy, enabling wireless power supply to implantable medical devices such as the NRU and NSU. Furthermore, the external BCI controller (ECU) and the implantable ICU communicate wirelessly for motion feedback and control, achieving a closed-loop control system of "perception-decision-feedback-adjustment," thereby improving the accuracy and adaptability of motion control.
