tumorimagingbench 0.1.4

A package for tumor imaging feature extraction and benchmarking.

TumorImagingBench

A comprehensive framework for evaluating and comparing foundation model feature extractors for radiomics in medical imaging.

📋 Overview

TumorImagingBench is a robust platform that enables researchers and practitioners to:

• Extract meaningful features from medical images using state-of-the-art foundation models
• Compare performance metrics across diverse radiomics datasets
• Systematically evaluate model stability, robustness, and interpretability
• Benchmark novel foundation models against established approaches

This framework bridges the gap between advancing foundation models and their practical application in medical imaging analysis.

🔍 Key Features

• Unified Interface: Common API for all foundation model extractors
• Comprehensive Evaluation: Standardized metrics across multiple datasets
• Interpretability Tools: Generation of saliency maps and attribution analysis
• Extensible Architecture: Easily integrate new models and datasets

🚀 Usage

Feature Extraction

from models import CTClipVitExtractor, FMCIBExtractor

# Initialize a model
model = FMCIBExtractor()
model.load()

# Extract features from a sample
features = model.extract(sample_path)

For systematic feature extraction across datasets, we provide dedicated scripts in the evaluation/ directory. These scripts offer a standardized approach that can be extended to new datasets through our base feature extractor class.

Model Evaluation

For examples of model evaluation on different datasets, explore the notebooks in the notebooks/modelling/ directory. These notebooks demonstrate:

• Feature extraction workflows
• Model training and validation
• Performance analysis and comparison
• Visualization of results

📈 Analysis Tools

Our repository includes specialized analysis notebooks:

Notebook	Purpose
stability_analysis.ipynb	Evaluate model stability with various perturbations
robustness_analysis.ipynb	Assess model robustness to noise and transformations
saliency_analysis.ipynb	Visualize and analyze model activation maps
overall_analysis.ipynb	Compare aggregate performance across models and datasets
