Methods and systems for segmentation and rendering of inverted data

A system comprising:

• a non-transitory computer readable medium including a three dimensional (3D) dataset acquired by an ultrasound imaging system, the dataset defining a volume;
• and
• a processor configured to:
• sort data points of the 3D dataset into one of a first set or a second set;
• generate a mask corresponding to the 3D dataset, wherein data points of the mask corresponding to data points of the 3D dataset sorted into the first set are set to a first value and data points of the mask corresponding to data points of the 3D dataset sorted into the second set are set to a second value;
• determine an outer boundary of the data points of the mask set to the first value;
• define a second volume within the first volume based on the outer boundary;
• apply the mask to the 3D dataset to discard data points of the 3D dataset corresponding to data points outside the second volume to generate a subset of the 3D dataset;
• and
• generate an inverted render from the subset of the 3D dataset, wherein the inverted render is generated by rendering data points representing higher intensity signals with darker pixels than pixels used to render data points representing lower intensity signals,
• wherein the processor is further configured to filter the 3D dataset to increase a difference between signal values and noise values prior to comparing the data points of the 3D dataset to a threshold value.
