【摘要】：经颅磁刺激技术(transcranial magnetic stimulation,TMS)是一种无痛、无创、绿色的治疗和诊断技术。主要应用于神经医学领域和康复医学领域。经颅磁刺激的临床研究显示,该技术在治疗和诊断的过程中可能使受试者感到不适,即存在安全性问题,因此该技术并没有得到广泛的应用。针对经颅磁刺激治疗和诊断过程中存在使受试者感到不适症状的问题,即经颅磁刺激的安全性问题,本文提出了基于经颅磁刺激的磁场测量结构。在经颅磁刺激治疗和诊断过程中,以磁场测量结构替代受试者,磁场测量结构能够反馈经颅磁刺激治疗和诊断过程中其所在区域的磁场分布,依据磁场分布分析经颅磁刺激治疗和诊断过程中是否存在潜在的安全性风险。磁场测量结构的提出为提高经颅磁刺激的安全性提供了测量依据和物理基础。对经颅磁刺激设备的改进具有一定的指导意义。针对提出的磁场测量结构,本文设计了三维磁场测量传感器和三维磁场测量传感器标定平台。提出了三维磁场测量传感器和三维磁场测量传感器标定平台的标定方法,并进行了理论分析、实验和实验结果误差分析。实验结果表明,三维磁场测量传感器标定平台的标定实验误差1%,所设计三维磁场测量传感器标定实验误差1.5%,在误差允许的范围(5%)内。因此所设计的三维磁场测量传感器标定平台可用于标定三维磁场测量传感器,标定的三维磁场测量传感器可用于磁场测量结构进行磁场测量。
[Abstract]:Transcranial magnetic stimulation is a painless, noninvasive, green technique for treatment and diagnosis. Mainly used in the field of neuromedicine and rehabilitation medicine. The clinical study of transcranial magnetic stimulation (TMS) shows that the technique may make the subjects feel uncomfortable in the course of treatment and diagnosis, that is, there are safety problems, so the technique has not been widely used. In view of the problem of the safety of transcranial magnetic stimulation in the treatment and diagnosis of transcranial magnetic stimulation, a magnetic field measurement structure based on transcranial magnetic stimulation is proposed. In the treatment and diagnosis of transcranial magnetic stimulation, the magnetic field measurement structure was used to replace the subjects. The magnetic field measurement structure could feedback the magnetic field distribution in the region of transcranial magnetic stimulation therapy and diagnosis. Potential safety risks in transcranial magnetic stimulation therapy and diagnosis are analyzed based on magnetic field distribution. The structure of magnetic field measurement provides the basis of measurement and physics for improving the safety of transcranial magnetic stimulation. It has certain guiding significance for the improvement of transcranial magnetic stimulation equipment. Aiming at the structure of magnetic field measurement, the calibration platform of three dimensional magnetic field measurement sensor and three dimensional magnetic field measurement sensor is designed in this paper. The calibration methods of the three dimensional magnetic field measurement sensor and the calibration platform of the three dimensional magnetic field measurement sensor are put forward, and the theoretical analysis, the error analysis of the experimental results and the experimental results are carried out. The experimental results show that the calibration error of the 3D magnetic field sensor calibration platform is 1 and the calibration error of the designed 3D magnetic field sensor is 1.5, within the error allowable range of 5. Therefore, the calibration platform of the 3D magnetic field measurement sensor can be used to calibrate the three-dimensional magnetic field measurement sensor, and the calibrated three-dimensional magnetic field measurement sensor can be used to measure the magnetic field of the magnetic field measurement structure.
