Overview:

This repository provides the code implementation for our paper, "Compositional Segmentation of Cardiac Images Leveraging Metadata." Our work presents a novel compositional segmentation approach to efficiently segment cardiac structures by integrating metadata, such as patient demographics and acquisition parameters, to modulate the segmentation network conditionally.

Key Contributions:

Compositional Segmentation: A hierarchical approach that performs super and sub-segmentation.

Super-segmentation: Localizes the heart.

Sub-segmentation: Further segments detail structures within the heart, including the left and right ventricles (LV, RV) and the myocardium (MYO).

Cross-Modal Feature Integration (CMFI): We introduce a CMFI module to leverage metadata (e.g., scanner type, medical condition, demographic details) as additional context, enhancing segmentation accuracy and robustness.

Evaluation:

Our approach was evaluated on two modalities using publicly available datasets:

M&Ms-2 Dataset (MRI)

CAMUS Dataset (Ultrasound)

Results demonstrate state-of-the-art segmentation performance across diverse cardiac imaging modalities.

Training Steps

Segmentation Model

The segmentaton models do not apply any activation on logits, so add activation after the last 1x1 conv layer or incorporate it in your loss function. Change Num_Classes to your (Segmentation class + 1).(1 for background). We have provided both versions

Model_with_CMFI

Model_without_CMFI
