Abstract: 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.

Abstract: A process for visualization of a needle in an ultrasound image comprises defining a region of an ultrasound image in which a body of a needle is expected using a needle tracking system to predict the location of the needle. The process also includes assigning a probability to a plurality of pixels within the region of the ultrasound image of being representative of the body of the needle, and modifying the display of each pixel having an assigned probability within a predetermined range.

Abstract: An ultrasound device determines a position and orientation of a surgical instrument based at least in part on tracking information, such as magnetic field strength, emitted by an emitter of a tracking system and detected by a sensor of the tracking system. The sensor and the emitter are attached to or within a different one of a probe of the ultrasound device and the surgical instrument. The ultrasound device determines an ultrasound imaging parameter, such as an ultrasound beam steering angle, based at least in part on the determined position and orientation of the surgical instrument. The ultrasound device applies the ultrasound imaging parameter to acquire ultrasound image data of a target. The ultrasound device generates an ultrasound image based on the acquired ultrasound image data of the target. The ultrasound image includes a representation of the surgical instrument. The surgical instrument may be a needle.
