  • Publication number: 20230107629
    Abstract: Embodiments disclosed herein are directed to a non-uniform, targeted ultrasound image modification system. The system can image a target area using ultrasound and can determine one or more target locations within the target area. Further the system can determine a location and orientation of a medical device to overlay a trajectory onto the target area. A user can further modify the one or more target locations as needed. The user can then modify an image parameter for the target area, and can further modify an image parameter for one or more target locations independently of the target area. This allows a user to modify the image of the target location to suit the position, tissue structure, or a procedure taking place there without affecting the image quality of the rest of the target area, or other target locations.
