Abstract
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.
