# Dataset Description

The files for the data challenge can be found in Zenodo:  

Link for training set-> [Training data set] (https://doi.org/10.5281/zenodo.17659415).

The .zip folder has the following structure:    
Thrombus_ultrasound_dataset_1_training/.   
|── train/   
│    |── file1.dcm   
│    |── file2.dcm   
│    |── ......     
|── train.csv    

The train.csv contains both meta data that can be used while training, such as participant's age (years), sex (F, M), height (cm), weight (kg), thigh circumference (cm), limb (L for left, R for right), anatomical site (CFV, GS, FV, PV) and vein compressibility (2, 1, 0), and the predictions for **Thrombosis [0, 1]**, per DICOM file.

Link for testing set-> [Testing data set] (https://doi.org/10.5281/zenodo.17664207).    

Thrombus_ultrasound_dataset_1_testing/.   
|── test/   
│    |── file1.dcm   
│    |── file2.dcm   
│    |── ......     
|── test.csv    

The test.csv is similar to the training.csv with the **Limb**, **Anatomical Site**, **Compressibility** and **Thrombosis** attributes missing.   

## Columns
For the training.csv and testing.csv.   
*   File Name - The filename of the anonymized DICOM file with the compression ultrasound. 
*   SubjectID - the ID of the participants the file belongs too. Multiple files can have the same subjectID, indicating the same participant.
*   Age - Participant's age (years)
*   Sex - Participant's sex (F for female, M for male). 
*   Height - Participant'  height (cm). 
*   Weight - Participant's weight (kg). 
*   Thigh Circumference - Participant's thigh circumference (cm)  
*   Limb - Limb the video is referred to. L for left limb, or R for right limb.
*   Anatomical Site - The anatomical site veins are visualised to. CFV: common femoral vein, GS: great saphenous,  FV: femoral vein, PV: popliteal vein.
*   Compressibility - Indicator of vein compressibility. 2: fully, 1: partially, 0:none
*   Thrombosis - Indicates the presence of thrombosis in propabilities. 0: no thrombosis, 1: thrombosis
