Abstract
AbstractPower Doppler ultrasound is a sonography technique to detect and visualise blood circulation. Its acquired image sequences suffer from poor temporal resolution and artefacts caused by aliasing, noise, large displacements, shearings or out‐of‐plane movements. These pitfalls distort flow fields and have unforeseen consequences on flow‐based temporal interpolations. We propose a method to detect artefacts caused by such distorted flow fields and to improve the visual quality by replacing regions with detected artefacts by locally better results. This is demonstrated on real data.
