Fast spectroscopic imaging such as spiral CSI can be used for applications such as real time metabolite imaging or real time temperature mapping. While methods to reduce the data acquisition time have been continuously developed, reconstruction times have been prolonged. We demonstrate the usage of parallel computing to reduce the reconstruction time of spiral CSI. By using a multi-threading approach, reconstruction times during the gridding routine can be shortened to by a factor of eight.
