Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] In one embodiment, such as figure 1 As shown, a functional magnetic resonance imaging method is provided, and the method specifically includes:
[0022] Step 102, acquiring navigation data and measurement data collected in (k-t) space by using the sampling mode of the partially separable function algorithm.
[0023] Since it is difficult to obtain MR (magnetic resonance, magnetic resonance) data through dense sampling, there will be a trade-off between spatial resolution and temporal resolution, that is, if the spatial resolution increases, the temporal resolution will decrease. , converse...
