AI Technical Summary
Existing intravascular ultrasound imaging systems inevitably remove effective signals during the artifact removal process, affecting doctors' judgment of the internal condition of blood vessels.
By acquiring the current frame image and using pre-obtained artifact parameters for artifact removal, the numerical relationship between the proportion of artifact signals and effective signals in the blind zone is analyzed. The artifact parameters are then adjusted to obtain the adjusted parameters, which are applied to the artifact removal of the next frame image to ensure that as many artifact signals as possible are removed while retaining the effective signals.
This technology achieves the goal of removing artifact signals while preserving the effective signals in intravascular ultrasound images to the maximum extent, thus improving the accuracy of doctors' judgment of the internal condition of blood vessels.
