1. A method for ultrasound imaging, comprising:
- generating a volume-rendered image with at least one of shading and shadowing from a three-dimensional ultrasound dataset, the shading and shadowing based on an angle between a probe axis of a transducer probe used to acquire the three-dimensional ultrasound dataset and a viewing direction of the volume-rendered image.

Abstract
Various methods and systems are provided for generating a volume-rendered image with shading from a three-dimensional ultrasound dataset. As one example, a method for ultrasound imaging includes generating a volume-rendered image with shading and shadowing from a three-dimensional ultrasound dataset, the shading and shadowing based on an angle between a probe axis of a transducer probe used to acquire the three-dimensional ultrasound dataset and a viewing direction of the volume-rendered image.

10. A method for ultrasound imaging, comprising:
-
generating a volume-rendered image with at least one of a first shading and a first shadowing from a three-dimensional ultrasound dataset, the at least one of the first shading and the first shadowing based on an angle between a probe axis of a transducer probe used to acquire the three-dimensional ultrasound dataset and a viewing direction of the volume-rendered image; displaying the generated volume-rendered image; and in response to a change in the angle, updating the volume-rendered image with at least one of a second shading and a second shadowing, different than the first, the at least one of the second shading and the second shadowing based on the change in the angle, and displaying the updated volume-rendered image. - View Dependent Claims (11, 12, 13, 14, 15, 17)

18. An ultrasound imaging system having an anisotropic point spread function, comprising:
-
a transducer probe adapted to scan a volume of interest; a display device; a user interface; and a processor in electronic communication with the transducer probe, display device, and user interface, where the processor is configured to; generate a volume-rendered image from three-dimensional ultrasound data acquired with the transducer probe; apply one or more shading and shadowing parameters to the volume-rendered image; adjust the one or more shading and shadowing parameters based on an angle between a probe axis of the transducer probe and a viewing direction of the volume-rendered image; and display the volume-rendered image on the display device. - View Dependent Claims (19, 20)
