First Claim
Patent Images
1. An ultrasound system, comprising:
- a first processor configured to form volume data by using a plurality of ultrasound data;
an user interface coupled to the first processor and configured to receive region of interest (ROI) setting information including a size and a position of the ROI; and
a second processor coupled to the first processor and configured to set a plurality of sampling start points along edges of the volume data, a plurality of sampling points and a ray-casting direction on the volume data based on the ROI setting information, the second processor being further configured to move sampling start points positioned inside or outside the ROI to be positioned at the ROI to render the volume data.

Abstract
There is disclosed an embodiment for volume data rendering. A first processor forms volume data by using a plurality of ultrasound data. A user interface coupled to the first processor receives region of interest (ROI) setting information including a size and a position of the ROI. A second processor coupled to the first processor sets a plurality of sampling start points along edges of the volume data, a plurality of sampling points and a ray-casting direction on the volume data based on the ROI setting information. The second processor is configured to move sampling start points positioned inside or outside the ROI to be positioned at the ROI to render the volume data.
