摘要

abstract method for improving needle visualization in ultrasound imaging; apparatus for improving needle visualization in ultrasound imaging; and the ultrasound imaging system The present invention provides a method and apparatus for improving the visualization of the ultrasound imaging needle (us) and an us imaging system. the apparatus comprises: a radon transform unit (tr) adapted to perform tr in a frame sequence to detect line resources in the frames, a frame comprising the us radiofrequency (rf) data obtained during insertion monitoring a needle in an individual or a reconstructed us image from rf data; a false needle feature removal unit adapted to remove thread features that remain substantially stationary between the frames as false needles while locating a thread feature extending between the structures such as the needle; and an overlay unit adapted to overlap the location of the thread feature such as the needle in a us image of a frame to produce an enhanced image to be displayed.
