Radiation measurement and simulation method for imaging
The patent US12066390B2 outlines a method and system for processing radiation data obtained from a radiation detector. The method involves receiving measured radiation that has passed through an object and simulating this radiation to generate a corresponding dataset. An offset is then calculated based on the differences between the measured and simulated radiation. This offset is used to estimate scatter radiation, which is further utilized to estimate the primary radiation. The claims detail various approaches to refine these estimations, including generating gains based on polynomial fittings of pixel values, resizing data for uniform resolution, and employing thresholds to filter pixel values for more accurate calculations.
Additionally, the system described in the patent comprises a processor, memory, and communication interface, which collectively facilitate the execution of the outlined method. The processor is tasked with fitting polynomials to pixel value vectors, generating intermediate gains, and creating offset images based on specific criteria. The claims also include provisions for handling subregions of the measured radiation, allowing for localized adjustments based on pixel values. Overall, the patent presents a comprehensive framework for enhancing the accuracy of radiation measurements through sophisticated data processing techniques, which could have applications in fields such as medical imaging and radiation therapy.
