Cleavage and Blastulation

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Area of Science:

Embryology
Medical Imaging
Artificial Intelligence

Background:

Accurate embryo quality assessment is vital for successful implantation.
Automatic blastocyst segmentation is challenging due to image noise and ambiguous boundaries.
Current methods struggle with precise identification of blastocyst structures.

Purpose of the Study:

To develop a novel transformer-based architecture for effective blastocyst component segmentation.
To improve the accuracy and reliability of automated embryo analysis.
To enhance the prediction of embryo implantation potential.

Main Methods:

Introduced BTFormer (Blastocyst Transformer), a novel transformer-based architecture.
Utilized an axial-free attention mechanism for efficient, long-range feature extraction.
Incorporated a soft aggregation operation for rotation consistency and diversified receptive fields.

Main Results:

Achieved state-of-the-art segmentation performance on a public dataset.
Reported high metrics: 93.86% accuracy, 91.81% precision, 92.25% recall, 92.02% Dice, and 85.45% Jaccard index.
Demonstrated effectiveness through extensive qualitative experimental results.

Conclusions:

BTFormer significantly enhances blastocyst segmentation accuracy.
The proposed method offers a robust solution for automated embryo quality assessment.
Improved segmentation contributes to better prediction of IVF success rates.
