Latest Patents

Lai Ching-Ming's latest patents include a "Self calibrating ring suppression filter for use in computed tomography." This innovation involves a CT system that utilizes a ring suppression filter to suppress ring artifacts in CT images. The system generates projections at various angles, with each projection containing measurements of multiple projection data signals. The ring suppression filter comprises a high pass filter, a histogram generator, and a combiner. The high pass filter produces an error signal measurement corresponding to each projection data signal, representing high-frequency components in the projections. The histogram generator creates a histogram signal that illustrates the relationship between the error signal measurements and the projection data signals. Finally, the combiner integrates the error signal and histogram signal measurements to produce a series of ring-corrected signals.

Another significant patent is the "Ring suppression filter for use in computed tomography systems." This patent shares similar features with the previous one, emphasizing the importance of the ring suppression filter in improving the accuracy of CT imaging by addressing ring artifacts.
