- Abstract summary: We show that the proposed 3D nnU-Net outperforms alternative 2D and recurrent segmentation methods.
Overall, the experimental results suggest that with sufficient training data, 3D nnU-Net could become the first automated tool to meet the standards of an everyday clinical device.

- Abstract: Deep learning-based methods have spearheaded the automatic analysis of
echocardiographic images, taking advantage of the publication of multiple open
access datasets annotated by experts (CAMUS being one of the largest public
databases). However, these models are still considered unreliable by clinicians
due to unresolved issues concerning i) the temporal consistency of their
predictions, and ii) their ability to generalize across datasets. In this
context, we propose a comprehensive comparison between the current best
performing methods in medical/echocardiographic image segmentation, with a
particular focus on temporal consistency and cross-dataset aspects. We
introduce a new private dataset, named CARDINAL, of apical two-chamber and
apical four-chamber sequences, with reference segmentation over the full
cardiac cycle. We show that the proposed 3D nnU-Net outperforms alternative 2D
and recurrent segmentation methods. We also report that the best models trained
on CARDINAL, when tested on CAMUS without any fine-tuning, still manage to
perform competitively with respect to prior methods. Overall, the experimental
results suggest that with sufficient training data, 3D nnU-Net could become the
first automated tool to finally meet the standards of an everyday clinical
device.

Existing databases for ECG delineation are small, being insufficient in size and in the array of pathological conditions they represent.
This article delves has two main contributions. First, a pseudo-synthetic data generation algorithm was developed, based in probabilistically composing ECG traces given "pools" of fundamental segments, as cropped from the original databases, and a set of rules for their arrangement into coherent synthetic traces.
Second, two novel segmentation-based loss functions have been developed, which attempt at enforcing the prediction of an exact number of independent structures and at producing closer segmentation boundaries by focusing on a reduced number of samples.
