Area of Science:

Cardiovascular computational modeling
Medical image analysis
Deep learning applications in healthcare

Background:

Cardiovascular disease diagnosis and treatment rely on accurate computational models.
Current methods for creating these models are manual, time-consuming, and complex.
Automating vascular model generation is crucial for advancing cardiovascular research.

Purpose of the Study:

To introduce SeqSeg, a novel deep learning algorithm for automatic vascular segmentation.
To enhance the efficiency and accuracy of generating image-based cardiovascular models.
To overcome limitations of existing manual and automated segmentation techniques.

Main Methods:

SeqSeg utilizes a sequential segmentation approach with local U-Net-based inference.
The algorithm processes medical image volumes (CT and MR) to trace and segment vascular structures.
Performance was evaluated on aortic and aortofemoral models against benchmark nnU-Net models.

Main Results:

SeqSeg demonstrated superior performance in segmenting complete vasculature compared to benchmark models.
The algorithm successfully generalized to segment vascular structures absent in the training data.
SeqSeg offers a more efficient and comprehensive approach to cardiovascular model generation.

Conclusions:

SeqSeg provides an effective deep learning solution for automated vascular modeling.
This method significantly improves the completeness and generalizability of image-based cardiovascular models.
SeqSeg has the potential to accelerate cardiovascular disease research and clinical applications.
