In this work a simple and general CSI reconstruction framework is presented based on a discretized forward model of the encoding process. Image reconstruction is then simply performed via direct matrix inversion. The method takes advantage of the generally low image resolution used in hyperpolarized 13C CSI and can readily be implemented on modern computers.
