1. A medical imaging system comprising: a data store of reconstruction procedures configured to identify a plurality of reconstruction procedures; a selector configured to select at least two reconstruction procedures from the data store of reconstruction procedures based on a received input, each reconstruction procedure being optimized for one or more image characteristics; a reconstructor configured to concurrently perform the selected at least two reconstruction procedures on a first dataset of imaging data of a first imaging modality, each reconstruction procedure generates at least one image from the data set, and on a second data set of imaging data of a second imaging modality which is different than the first imaging modality, wherein each reconstruction procedure generates at least one image from the second data set; a fuser configured to fuse the generated medical images of the first imaging modality and the second imaging modality to create the medical diagnostic image which includes characteristics from each generated image, wherein the data sets of imaging data are received from one or more of: a positron emission tomography (PET) device; an x-ray computed tomography (CT) device; and a hybrid CT/PET tomography device; and a display device configured to display the medical diagnostic image.
