Abstract
Embodiments for performing surface rendering upon volume data in an ultrasound system are disclosed. An ultrasound data acquisition unit transmits and receives ultrasound signals to and from a target object to thereby acquire ultrasound data corresponding to a plurality of frames. A volume data forming unit forms volumes data corresponding to the plurality of frames based on the ultrasound data. The volume data includes a plurality of voxels. A processing unit detects edges of a region of interest (ROI) of the target object in the volume data and performs surface rendering upon voxels within the detected edges to thereby form a 3-dimensional ultrasound image.

An ultrasound system, comprising:
- an ultrasound data acquisition unit configured to transmit and receive ultrasound signals to and from a target object to thereby acquire ultrasound data corresponding to a plurality of frames;
- a volume data former configured to generate volume data corresponding to the plurality of frames based on the ultrasound data, the volume data including a plurality of voxels;
- and
- a processing unit configured to detect edges from frames included in the volume data, detect voxels of the edges connected to each other, label upon the detected edges, group the labeled voxels into a plurality of voxel groups, determine a voxel group based on the number of voxels among the voxel groups, set the determined voxel group as a region of interest (ROI), set a first parameter including a parameter associated with surface reflection and a second parameter for processing skin tone based on a user input, and perform surface rendering upon voxels within the ROI by using the first parameter and the second parameter to thereby form a 3-dimensional ultrasound image.
A method of performing surface rendering upon volume data in an ultrasound system including an ultrasound data acquisition unit, a volume data forming unit and a processing unit, comprising:
- a) at the ultrasound data acquisition unit, transmitting and receiving ultrasound signals to and from a target object to thereby acquire ultrasound data corresponding to a plurality of frames;
- b) at the volume data forming unit, forming volume data corresponding to the plurality of frames based on the ultrasound data, the volume data including a plurality of voxels;
- c) at the processing unit, detecting edges from frames included in the volume data, detecting voxels of the edges connected to each other, labeling upon the detected edges, grouping the labeled voxels into a plurality of voxel groups, determining a voxel group based on the number of voxels among the voxel groups, setting the determined voxel group as a region of interest (ROI);
- d) at the processing unit, setting a first parameter including a parameter associated with surface reflection and a second parameter for processing skin tone based on a user input;
- and
- e) at the processing unit, performing surface rendering upon voxels within the ROI by using the first parameter and the second parameter to thereby form a 3-dimensional ultrasound image.
