AI Technical Summary
Existing CT scanning systems are difficult to achieve effective ray hardening correction and detector response consistency correction in multi-energy X-ray scenarios, resulting in artifacts in image reconstruction and long data acquisition and analysis time.
By determining the multi-energy X-ray attenuation data of the target model at different rotation angles, and calculating the measured attenuation path of the X-ray passing through the target model, using the conversion factor between the attenuation data under single-energy X-rays and the attenuation path, a mapping function between the single-energy X-ray attenuation data and the multi-energy X-ray attenuation data is established to realize beam hardening correction and detector response consistency correction.
It effectively reduces data acquisition and analysis time, improves the accuracy and consistency of image reconstruction, and reduces the cost of the model and operation difficulty.
