# 🏥 Generalized Medical Image Modality Dataset

A curated, balanced dataset for training **medical imaging modality classifiers**.
Contains images from four modalities (CT, MRI, X-Ray, Ultrasound) spanning multiple
anatomical regions to ensure robust generalization.

> **Total images:** 9,450 | **Target:** 9,450

## 🚀 Usage

Images are packaged in `modality_dataset.zip`. Extract and use directly:

```python
import zipfile
with zipfile.ZipFile("modality_dataset.zip", "r") as z:
    z.extractall("./modality_dataset")
```

The top-level folder names (`CT`, `MRI`, `XRAY`, `US`) are the **class labels** for
the modality classifier. Sub-folders represent the anatomical regions used as data sources.
