Abstract: Rendering quality parameter values are automatically set or adjusted as a function of acquisition ultrasound parameter values. The rendering quality is automatically selected based on the acquisition quality, such as providing for a higher quality or quality rendering for slower acquisitions. More than two rendering states are provided for a respective, more than two different quality settings. For example, different quality settings are provided for streaming (non-repetitive on-going rendering), manipulation (edits of a rendered image), frozen and animation states (repetitive or looped rendering). Since the frozen state is less limited by processing time, the frozen state may be rendered with a highest quality or quality. The rendering is provided with two different sampling density variables, such as an in-plane or XY sampling density and a viewing direction or z sampling density. The separation may allow for a more versatile trade-off between image quality and performance.
