1. A method for computing volumetric perfusion using a computed tomography imaging system, the method comprising: irradiating a spatially dynamic object within a field of view of the computed tomography imaging system for requisite view angle positions of the gantry; operating the computed tomography imaging system in a continuous data acquisition mode to acquire projection data representative of the spatially dynamic object; processing the projection data to generate time-resolved projection data; generating reconstructions using the time-resolved projection data; and computing the volumetric perfusion in the spatially dynamic object using the reconstructed data.
