Query: 4D Cardiac Ultrasound Standard Plane Location by Spatial-Temporal
  Correlation   Echocardiography plays an important part in diagnostic aid in cardiac
diseases. A critical step in echocardiography-aided diagnosis is to extract the
standard planes since they tend to provide promising views to present different
structures that are benefit to diagnosis. To this end, this paper proposes a
spatial-temporal embedding framework to extract the standard view planes from
4D STIC (spatial-temporal image corre- lation) volumes. The proposed method is
comprised of three stages, the frame smoothing, spatial-temporal embedding and
final classification. In first stage, an L 0 smoothing filter is used to
preprocess the frames that removes the noise and preserves the boundary. Then a
compact repre- sentation is learned via embedding spatial and temporal features
into a latent space in the supervised scheme considering both standard plane
information and diagnosis result. In last stage, the learned features are fed
into support vector machine to identify the standard plane. We eval- uate the
proposed method on a 4D STIC volume dataset with 92 normal cases and 93
abnormal cases in three standard planes. It demonstrates that our method
outperforms the baselines in both classification accuracy and computational
efficiency.
