Background:

Medical imaging is crucial for cancer diagnosis and treatment.
Limited medical image data hinders deep learning model training for tumor segmentation.

Purpose of the Study:

To address the challenge of insufficient data for deep learning in tumor segmentation.
To expand small medical image datasets using a novel data augmentation method.

Main Methods:

The proposed method involves image cutting (horizontal, vertical, diagonal) and mirroring for data augmentation.
Deep learning networks (Mask-RCNN, U-Net) are trained on augmented data.
Boundary reconstruction is applied to refine the segmentation of the original tumor.

Main Results:

The data augmentation technique significantly improved the Dice Similarity Coefficient (DSC) compared to no augmentation.
Improvements of up to 13.74% in DSC were observed.
The method outperformed traditional augmentation techniques like cropping, rotating, and mirroring.

Conclusions:

The proposed data augmentation method demonstrates superior performance for single tumor segmentation compared to traditional approaches.
This technique is effective in enhancing deep learning model accuracy with limited medical imaging data.
