What Aspects Should Be Considerded In Registration Submission When Multiple Receiving Coils In MRI System Are Used Jointly?

In the case of joint use of multiple receiving coils in the MRI system, the following issues shall be considered in the registration submission:

1. The combination mode, patient positioning mode and corresponding scanning position of the coil should be described in the overview material;
2. The performance of SNR, uniformity, 2D scanning layer thickness, spatial resolution and ghost should be provided in the research data;
3. The product technical requirements shall include the performance requirements of single coil and the performance requirements of multi coil joint use;

For clinical evaluation, the joint combined coil should be combined with the appropriate scanning position.
