Abstract
Methods and systems are provided for high-resolution computed tomography imaging. In one embodiment, a method comprises detecting, with a detector array comprising a plurality of individual detectors each configured with a first number of energy bins, photons generated by an x-ray source and attenuated by a subject to be imaged, generating a first dataset, for a virtual detector array comprising a combination of individual detectors and macro-detectors, by selectively aggregating a subset of the individual detectors into the macro-detectors with a second number of energy bins, generating a second dataset, for an augmented detector array comprising the plurality of individual detectors each configured with the second number of energy bins, by up-sampling the first dataset, and reconstructing an image of the subject from the second dataset. In this way, high-resolution detector arrays can acquire minimal data while maintaining a high image resolution and spectral resolution.
