The method, device and system for improving the visualization of the needle in the medical ultrasound imaging

The present invention provides a method, device and system for improving the needle visualization in ultrasound imaging, said method comprising: a setting step for setting a sampling depth corresponding to a depth of part or target tissue in the body of a patient; and a determination step of automatically determining a needle frame steering angle and an ultrasonic operating frequency for the needle detection frame on the basis of sampling depth. In the embodiments of the present invention, both needle frame steering angle and ultrasonic operating frequency for the needle frame detection and the filter kernel to improve the edge filtering depend upon the detected needle frame from the sampling depth, thus providing an improved needle visualization in ultrasound imaging of the sample at different depths without the assistance of user or additional hardware change can be achieved.
