摘要:
A method and an apparatus or needle visualization enhancement in ultrasound (US) imaging includes a Radon transform (RT) unit configured to perform RT on a sequence of frames to detect line features in the frames, where a frame includes US radio-frequency (RF) data obtained during monitoring the insertion of a needle into a subject or an US image reconstructed from the RF data. Further, a false needle feature removing unit is configured to remove line features which remain substantially stationary among the frames as false needles while locating a line feature which extends among the frames as the needle and an overlaying unit is configured to overlay the location of the line feature as the needle on an US image of a frame to produce an enhanced image to be displayed.
