The present invention discloses a method, apparatus and system for enhancing needle visualization in ultrasound imaging, said method comprising: a setting step for setting a scanning depth corresponding to a depth of a part or tissue target in a patient's body; and a determining step for automatically determining a needle frame steering angle and an ultrasound working frequency for needle frame collection based on the scanning depth. In the embodiments of the present invention, the needle frame steering angle and ultrasound working frequency for needle frame collection and the filter kernel for enhancing edge filtering of the collected needle frame are both dependent upon the scanning depth, and thereby can achieve enhancing needle visualization in ultrasound imaging for scanning at different depths without participation of the user or extra change of hardware.
