👀 Introduction

This is the official repository for A Concept-based Interpretable Model for the Diagnosis of Choroid Neoplasias using Multimodal Data This study introduces a multimodal concept-based interpretable model (MMCBM) tailored to distinguish uveal melanoma (0.4-0.6 per million in Asians) from hemangioma and metastatic carcinoma following the clinical practise. We collected the largest dataset on Asians to date on choroid neoplasm imaging, encompassing over 750 patients from 2013 to 2019. Our model integrates domain expert insights from radiological reports and differentiates between three types of choroidal tumors, achieving an $F_1$ score of 0.91.

🔍 Dataset

To support the development of interpretable models for diagnosing choroidal tumors, we built the Choroid Tri-Modal Imaging (CTI) dataset, an anonymized, multimodal, and annotated collection of medical images from Beijing Tongren Hospital encompassing Fluorescence Angiography (FA), Indocyanine Green Angiography (ICGA), and Ocular Ultrasound (US) images. The construction of this dataset was approved by the Ethics Committee of Beijing Tongren Hospital.

License:

CTI dataset is only used for academic research. Commercial use in any form is prohibited.
The copyright of the dataset belongs to Beijing Tongren Hospital.
Without prior approval, you cannot distribute, publish, copy, disseminate, or modify CTI in whole or in part. 
You must strictly comply with the above restrictions.

Installation

1. Create a conda environment from the environment.yml file:

   conda env create -f environment.yml

2. Install from the requirements.txt file:

   pip install -r requirements.txt

Preparation

📍download download the checkpoint from the model checkpoint, and put it in the work_dir/result directory. After downloading, the directory structure should look like this:

• backbone: pretrained encoders trained on the same dataset split as MMCBM. Put the backbone in

   work_dir/result/Efficientb0_SCLS_attnscls_CrossEntropy_32

• MMCBM (Optional): the checkpoint of the MMCBM model. Put the MMCBM in

  work_dir/result/CAV_m2CBM_sigmoid_C0.1CrossEntropy_32_report_strict_aow_zero_MM_max

📍 ⚙️configuration

• ChatGPT fill in the openai_info section in params.py with your own api_key and api_base from OpenAI.
• Tencent Translation (Optional) fill in the tencent_info section in params.py with your own app_id and app_key from Tencent Cloud.

♻️ Training

To train the MMCBM, you should first download our CTI dataset and put it in the <work dir>/data directory. And then download the pre-trained backbone and put it in the <work dir>/result/Efficientb0_SCLS_attnscls_CrossEntropy_32 directory. Then you can run the following command in the terminal:

    python train_CAV_CBM.py --name <dirname of experiment> --backbone <backbone dir> --epoch 200 --lr 1e-3 --device 0 --bz 8 --k 0

For five-fold cross-validation, you can run the following command in the terminal:

    python execute_concept.py --name <dirname of experiment>  --bz 8  --backbone <backbone dir> --clip_name cav --device 1,2,3,4,5 --k 0,1,2,3,4,5 --lr 0.001

🔮 Usage

📍 Web Interface

1. Web Interface using Gradio (Recommended), our web interface is available at Interface Link.

2. you can also run this website locally by running the following command in the terminal:

   python web_interface.py

   then open the browser and enter http://127.0.0.1:7860/ to access the website.

3. We also provide a human evaluation website, used for doctors to diagnose the disease based on the model's prediction.

   • For blackbox model:

     python web_human_blackbox_evaluation.py

   • For MMCBM model:

     python web_human_mmcbm_evaluation.py

   then open the browser and enter http://127.0.0.1:7890 to access the website.

📍Command Line :

Command Line without Gradio. We also provide a bash script to run the model inference from the command line:

python mmcmb_inference.py
