Background:

Medical image segmentation is crucial for numerous applications.
Current research focuses on atlas-based whole-body segmentation.
Existing methods often require specialized algorithms for each structure.

Purpose of the Study:

To propose a general framework for segmenting multiple structures in medical images.
To improve segmentation by incorporating inter-structure spatial dependencies.
To provide automatic initializations for segmentation processes.

Main Methods:

Developed a general framework integrating inter-structure spatial dependencies.
Introduced a hierarchical approach by ranking structures based on dependencies.
Utilized existing segmentation algorithms within the new framework.
Learned the optimal structure ordering off-line.

Main Results:

The hierarchical framework improved individual segmentation performance.
The approach successfully provided automatic initializations for segmentation.
Demonstrated applicability to segmenting multiple structures in brain MR images.

Conclusions:

Inter-structure spatial dependencies offer a powerful way to enhance medical image segmentation.
The proposed framework is generalizable and improves upon existing methods.
This approach facilitates more accurate and automated segmentation of anatomical structures.
