研究目的
To diminish the need for training and to improve diagnostic accuracy in the detection of malignant melanoma using confocal laser scanning microscopy (CLSM) through computer-aided diagnostic systems.
研究成果
The study demonstrates that both multiresolution analysis and deep learning neural networks can effectively classify CLSM images of skin lesions, with the neural network achieving a 93% accuracy on the test set. However, the neural network approach requires large amounts of training data and computational power. The findings suggest that deep learning could play an important role in automated medical diagnostic systems, especially as parallelized hardware advances and data storage increases.
研究不足
The study's results are considered a proof of concept and not ready for clinical application due to the dataset being collected from a single department and region, potentially introducing unintentional bias. A larger, more diverse dataset would be necessary for real-world clinical use.
1:Experimental Design and Method Selection:
The study presents two approaches for the analysis of CLSM images: multiresolution analysis and deep layer convolutional neural networks. The multiresolution analysis uses wavelet transform to explore architectural structures at different spatial scales, while the convolutional neural networks learn discriminatory features directly from image data.
2:Sample Selection and Data Sources:
The dataset consisted of 6897 CLSM images of skin lesions, including benign common nevi and malignant melanoma, obtained from a university hospital.
3:List of Experimental Equipment and Materials:
Confocal laser scanning microscopy was performed with a Vivascope 1000 (Lucid Inc., USA) using a diode laser at 830 nm wavelength. A ×30 water-immersion objective lens with a numerical aperture of 0.9 was used.
4:9 was used.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Images were resized to 64 × 64 pixels for neural network analysis. The dataset was split into training and test sets for both multiresolution analysis and neural network training.
5:Data Analysis Methods:
For multiresolution analysis, features based on the wavelet transform were extracted and classified using the CART algorithm. For neural network analysis, a convolutional neural network based on the LeNet-5 structure was trained using the Keras deep learning library for Python.
