MRI成像装置通道数验收鉴定的研究

MRI Imaging Device Channel Number Acceptance Appraisal Research

该文验证磁共振射频系统实际通道数与厂商标称通道数的符合性及考察其对磁共振成像性能的影响。同时通过检测通道数增加与MRI系统图像噪声水平和对成像重建速度的关系,验证MRI射频系统接收通道数的多少与MRI信噪比、扫描时间等密切相关。

This paper verifies MRI RF system conformity of the actual channel number and the manufacturer’s nominal channel number, and inspects the actual channel number’s effect on the properties of magnetic resonance imaging(MRI). At the same time through detecting the increasing channel number’s relationship with MRI detection system image noise level and the image reconstruction speed, to verify the number of MRI RF system receiver is closely related with SNR, MRI scan time and so on.
