High volume rate 3D ultrasonic diagnostic imaging

A computer-readable, non-transitory medium storing software code representing instructions that, when executed by a computing system, cause the computing system to perform a method of displaying three-dimensional (3D) image data at a high frame rate, the method comprising:

• receiving at least two datasets of a volumetric region comprising moving tissue, wherein each dataset is obtained using spatially different scanline patterns at different acquisition times during tissue movement and comprise image data corresponding to sampled locales within the volume;
• attributing first data values to image data of a first dataset and second data values to image data of a second dataset, wherein the first and second data values correspond to respective sampled locales of the first and second data sets;
• generating interpolated data representing the volumetric region between the sampled locales of the first data set;
• attributing values to the interpolated data, thereby generating interpolated data values;
• comparing the second data values to the interpolated data values;
• and
• generating an image dataset, wherein the image dataset comprises image data of the first dataset and either:
• interpolated data when a first interpolated data value is substantially different from a second data value at the same sampled locale;
• or
• a portion of data from the second dataset when a first interpolated data value is substantially the same as a second data value at the same sampled locale.
