1. A method, comprising:
- generating a flat, 2D image from a 2D dataset including scalar image values without height values, the 2D dataset acquired with an ultrasound imaging system;
determining a gradient of height values from the scalar image values;
applying shading to the flat, 2D image using the determined gradient; and
displaying the shaded flat, 2D image, having a 3D appearance, via a display screen of the ultrasound imaging system.

Abstract
Various methods and systems are provided for shading a 2D ultrasound image, generated from ultrasound data, using a gradient determined from scalar values of the ultrasound image data. As one example, a method includes correlating image values of a dataset acquired with an ultrasound imaging system to height values; determining a gradient of the height values; applying shading to a 2D image generated from the dataset using the determined gradient; and displaying the shaded 2D image.

13. An ultrasound imaging system, comprising:
-
an ultrasound probe; a display device; and a processor communicatively connected to the ultrasound probe and the display device and including instructions stored in memory that, when executed during operation of the ultrasound imaging system, cause the processor to; access a 2D dataset, including only 2D scalar data and no 3D data, acquired with the ultrasound probe from the memory; generate a flat, 2D image from the 2D dataset, where each pixel of the flat, 2D image includes a scalar, image value; convert the scalar, image value of each pixel to a scalar, height value via a scalar valued function; determine a gradient surface normal for each scalar, height value; shade one or more pixels of the flat, 2D image using the gradient surface normal; and display the shaded flat, 2D image via the display device. - View Dependent Claims (14, 15)

16. A method, comprising:
-
generating a flat, 2D image from a 2D, B-mode dataset including scalar intensity values without height values, the 2D, B-mode dataset acquired with an ultrasound imaging system; determining a gradient of height values from the scalar image values by, for each pixel of the flat, 2D image, converting a first scalar intensity value of the scalar intensity values included in the 2D, B-mode dataset to a corresponding height value using a relationship between the first scalar intensity value and the height value; applying shading to the flat, 2D image using the determined gradient; and displaying the shaded flat, 2D image, having a 3D appearance, via a display screen of the ultrasound imaging system. - View Dependent Claims (17, 18, 19, 20)
