研究目的
To improve the accuracy, speed, cost, and accessibility of mammogram screenings by developing a remote and automatic screening system using web technologies and machine learning algorithms.
研究成果
The proposed system provides a novel and comprehensive solution for early breast cancer detection, with high accuracy in image acceptance and tumor identification, making it fast and accessible through a telemedical service.
研究不足
The tumor identifier was validated on a relatively small dataset (INbreast), and no hyperparameter optimization was performed. Downscaling of images may have removed details, and the system could be improved with dataset augmentation and transfer learning.
1:Experimental Design and Method Selection:
The study involves designing a web application for mammogram upload and analysis, employing a one-class SVM with variational autoencoder for image acceptance, and a ResNet-101 Faster R-CNN for tumor identification.
2:Sample Selection and Data Sources:
Mammogram images from the DDSM (Digital Database for Screening Mammography) for training and INbreast database for validation, with specific BI-RADS scores (1, 5, 6) used.
3:List of Experimental Equipment and Materials:
Computational resources including Intel i7 processor, NVIDIA Tesla K80 GPU, and software tools like TensorFlow, Flask, and Python.
4:Experimental Procedures and Operational Workflow:
Images are uploaded via a web interface, processed by the image acceptor to verify if they are mammograms, and if accepted, analyzed by the tumor identifier to locate malignancies. Preprocessing includes CLAHE and color mapping.
5:Data Analysis Methods:
Performance evaluated using metrics like misclassification rates and AUROC, with bootstrap sampling for confidence intervals.
