[0034] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.
[0035] See figure 1 The method for synthesizing and reconstructing output signals of quadrature coils in the MRI system includes the following six steps:
[0036] Step 1. Collect the two output signals of the quadrature coil in the MRI system:
[0037] The orthogonal coils in the MRI system are marked as I and Q respectively, and the magnetic resonance signals induced by the I and Q of the orthogonal coils are amplified and collected by their respective receivers to obtain the I circuits of the orthogonal coils. The original output signal S 1 And the original output signal S of the quadrature coil Q 2 ;
[0038] I original output signal S 1 And Q original output signal S 2 Both are a two-dimensional data set. If the magnetic resonance signal obtained by the respective receiver contains n layers, then the original output signal S 1 It is a two-dimensional signa...
