Measure the quality of B-ultrasound images

Evaluating image quality is to use some objective technical indicators to evaluate the effects of an imaging technique. In order to evaluate the quality of ultrasound images, the following parameters are generally used as the criteria for Image Quality Evaluation:

(1) Details resolution: the ability to clearly distinguish regions from smaller organizations.

(2) Contrast Resolution: The Contrast Resolution has two meanings: the ability to identify weak echo tissue when there is a bright reflection, and the ability to distinguish adjacent tissues when the ECHO is close.

(3) full-field uniformity: provides better fine resolution and contrast resolution throughout the display range. For example, in some low-grade ultrasonic instruments, high resolution is only available in the focus area of the sound bundle, while far-field and near-field resolutions are poor in deviation from the focus area, this is a typical example of full-field uniformity.

(4) time resolution: the interval between two frames. If the time interval is short, the frame rate is higher, and the system has better dynamic characteristics.
