Heart scans using MRI provide doctors with a clear view of the heart's structure, aiding in early detection of heart problems. However, making these scans work well with computers requires a significant amount of labeled data, which is time-consuming and labor-intensive.

Introducing PDFMSeg

A new method called PDFMSeg is changing the game. It utilizes a minimal amount of labeled data and a large amount of unlabeled data, making the process faster and more efficient. The method comprises two main components:

  1. Dynamic Mix of High and Low-Frequency Components: This technique enhances the clarity of heart structure boundaries by leveraging pseudo-labels.
  2. Partial Dice Loss: A specialized loss function that improves the accuracy of segmentation.

Superior Performance

Tests have shown that PDFMSeg outperforms other methods, achieving high scores on public datasets like ACDC and MSCMR. Even with just 10% of the data labeled, it performs exceptionally well. Additionally, the model is highly efficient, requiring fewer parameters and less computing power.

A Game-Changer for Medical Diagnostics

This innovative method could revolutionize heart scans, making them more accessible and accurate. Doctors could use it to diagnose heart diseases faster and more reliably. The code and models are openly available, encouraging further research and advancements in the field.
