1. An imaging system comprising: a list-mode memory which stores nuclear image data generated of a subject moving through a plurality of motion states in a list-mode; a clock configured to mark the list-mode data with time stamps; a motion sensor configured to sense motion states of the subject as the data is generated; at least one processor programmed to perform the steps of: sorting the stored list-mode data based on the motion state, reconstructing the list-mode data sorted into each of the motion states into a high spatial resolution, low temporal resolution image, each high spatial resolution, low temporal resolution image being in a different one of the plurality of the motion states, deriving from the high spatial resolution, low temporal resolution images transforms which transforms the list-mode data into one or more selected motion states, and reconstructing the stored list-mode data transformed to the one or more selected motion state into a static image with a high temporal resolution and a high spatial resolution or reconstructing the list-mode data transformed into each of a plurality of motion states into a dynamic series of images with high temporal resolution and high spatial resolution.
