Image processing system for photon-counting detector data transformation
The granted patent US12073491B2 outlines a sophisticated system for image processing that leverages energy resolved count data generated by a photon-counting detector. The system includes an input interface to receive this data, a count data transformer that applies calibration-based weights to convert the energy resolved count data into transformed count data, and a data converter that translates this transformed data into through-material path length data. This conversion allows the photon-counting detector to emulate the functionality of an energy integrating detector. Additionally, the system features an output interface for disseminating the resulting through-material path length data, and it may include a reconstructor to generate image data from this processed information.
Further claims detail the flexibility and adaptability of the system, such as the ability for the data converter to utilize the same weights across all pixels of the photon-counting detector and the inclusion of a user interface that permits users to modify these weights. The patent also specifies that the materials processed can include water or substances with similar radiodensity. Moreover, it describes a computer-implemented method that mirrors the system's functionality, along with a non-transitory computer-readable medium designed to store executable instructions for performing the outlined method. This patent represents a significant advancement in image processing technology, particularly in enhancing the capabilities of photon-counting detectors in medical imaging and other applications.
