# Brain Tumor FLAIR Classifier
基于单份三维 FLAIR NIfTI 的脑肿瘤病例级二分类模型
模型基于 `google/vit-base-patch16-224-in21k` 微调
输入 `.nii` 或 `.nii.gz`
输出 `yes_probability` 与 `yes` 或 `no` 分类结果
## Model Details
| 项目 | 内容 |
| --- | --- |
| 架构 | Vision Transformer |
| 输入 | 三维 FLAIR NIfTI |
| 病例聚合 | 25 张轴位有效切片的阳性概率均值 |
| 冻结阈值 | `0.548381` |
| 权重格式 | `safetensors` |
## Quick Start
```powershell
git lfs install
git clone <repository-url>
cd brain-tumor-flair-classifier
git lfs pull
python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install -e .
python examples\infer.py --input path\to\flair.nii.gz --output outputs\result.json
```
GPU 可用时默认使用 CUDA
```powershell
python examples\infer.py --input path\to\flair.nii.gz --device cpu
```
## Python API
```python
from brain_tumor_flair_classifier import FlairClassifier
classifier = FlairClassifier.from_pretrained('本地模型目录')
result = classifier.predict_nifti('path/to/flair.nii.gz')
print(result['yes_probability'])
```
发布到 Hugging Face 后可直接使用模型 ID
```python
classifier = FlairClassifier.from_pretrained('用户名/模型仓库名')
```
## Output
```json
{
"model_version": "v1",
"threshold": 0.548381,
"predicted_class": "yes",
"yes_probability": 0.721431,
"no_probability": 0.278569,
"evaluated_slices": 25
}
```
