+
+## Dataset Description
+This dataset was be modified from Lung segmentation dataset by Kónya et al., 2020  
+https://www.kaggle.com/sandorkonya/ct-lung-heart-trachea-segmentation
+
+The original nrrd files were re-saved in single tensor format with masks corresponding to labels: **(lungs, heart, trachea)** as numpy arrays using pickle.
+
+Each tensor has the following shape:  
+`number of slices, width, height, number of classes`  
+Where:
+- the width and height number of slices are individual parameters of each tensor id  
+- number of classes = 3
+
+In addition, the data was re-saved as **RGB images**, where each image corresponds to one ID slice, and their mask-images have channels corresponding to three classes: **(lung, heart, trachea)**.
+
+---
+
+## Content
+The dataset contains:
+- `images.zip` - images in RGB format  
+- `masks.zip` - segmentation masks in RGB format  
+- `train.csv` - csv file with image names
