Ultrasound diagnostic system and method of automatically controlling brightness and contrast of a three-dimensional ultrasound image
First Claim
1. A method of automatically controlling a brightness and a contrast of a three-dimensional (3D) ultrasound image, comprising the steps of:
- a) creating 3D ultrasound image data based on ultrasound echo signals;
b) setting a critical value for rendering the 3D ultrasound image data;
c) rendering the 3D ultrasound image data by using the critical value to form the 3D ultrasound image;
d) analyzing a histogram of the 3D ultrasound image to set image parameters for the 3D ultrasound image; and
e) adjusting the brightness and the contrast of the 3D ultrasound image based on the image parameters.

Abstract
The present invention relates to an ultrasound diagnostic system and method for automatically controlling the brightness and contrast of a three-dimensional (3D) ultrasound image. The method for automatically controlling the brightness and contrast of a 3D ultrasound image includes the steps of: creating 3D ultrasound image data based on ultrasound echo signals; setting a critical value for rendering the 3D ultrasound image data; rendering the 3D ultrasound image data by using the critical value to form a 3D ultrasound image; analyzing a histogram of the 3D ultrasound image to set image parameters for the 3D ultrasound image; and adjusting the brightness and contrast of the 3D ultrasound image based on the image parameters.
