# Lighter zoo x CT-FM: Through lighter zoo we provide several models pre-trained using the CT-FM vision foundation model for Computed Tomography (CT) scans.
|
| 11 |
+
CT-FM is a large-scale 3D image-based pre-trained model designed for diverse radiological tasks. The model was pre-trained on 148,000 CT scans from the Imaging Data Commons using label-agnostic contrastive learning.
|
| 12 |
+
## Model Details
|
| 13 |
+
The model demonstrates strong capabilities across multiple tasks:
|
| 14 |
+
- Whole-body
|
| 15 |
+
- Heterogenous umor segmentation
|
| 16 |
+
- Head CT triage
|
| 17 |
+
- Medical image retrieval
|
| 18 |
+
- Semantic understanding of anatomical structures
|
| 19 |
+
Key features:
|
| 20 |
+
- Learns anatomical clustering without explicit labels
|
| 21 |
+
- Identifies similar anatomical structures across different scans
|
| 22 |
+
- Shows robustness in test-retest scenarios
|
| 23 |
+
- Provides interpretable salient regions in its embeddings
|
| 24 |
+
|
| 25 |
+
## Models Available
|
| 26 |
+
- Feature extractor `ct_fm_feature_extractor` which can be used for several feature-based tasks such as image retrieval, semantic search and outlier detection
|
| 27 |
+
- Fine-tuned whole body segmentation model `whole_body_segmentation` that segments 117 labels from the TotalSegmentator dataset
|
| 28 |
+

+
## Installation
|
| 30 |
+
We provide pre-trained as well as fine-tuned models in the `lighter-zoo` package that interfaces with HF to provide easy to use APIs
|
| 31 |
+
|
| 32 |
+
To install the `lighter-zoo` package, use pip:
|
| 33 |
+
```bash
|
| 34 |
+
pip install lighter-zoo
|
| 35 |
+
```
|
| 36 |
