Refined reconstruction of time-varying data

A system for data reconstruction, comprising:

• a non-transitory memory device for storing computer readable program code;
• and
• a processor in communication with the memory device, the processor being operative with the computer readable program code to:
• perform a first four-dimensional reconstruction of time-varying data to generate a four-dimensional Digital Subtraction Angiography (DSA) dataset of an object of interest,
• identify a volume of interest in the four-dimensional DSA dataset,
• extract the volume of interest from the four-dimensional DSA dataset to generate a volume array,
• refine the volume of interest based on the volume array to generate a refined dataset, and
• perform a second four-dimensional reconstruction based on the refined dataset to generate a zoomed-in four-dimensional representation of the volume of interest.
