摘要 |
In an X-ray diagnostic installation and correction method wherein comet artifacts in the unprocessed image can be corrected, a geometrical analysis of the comet artifacts is implemented, an estimated reference value is determined from the original signal using the analysis result, an estimated detail signal is determined from the original signal using the analysis result, and the comet artifacts are corrected on the basis of the estimated reference value and the estimated detail signal.
