How to Create a Deep Learning Model for Chest CT-Scans Running on Django in Python

In this step-by-step guide, we will walk through the process of creating our own deep learning model for analyzing chest CT-scans and seamlessly integrating it with Django, a popular Python web framework. The project allows users to upload their chest CT-scans to a web application and receive accurate predictions based on the deep learning model's analysis. Before we dive in, make sure to have Python and Django installed, along with the essential libraries like TensorFlow and Keras for deep learning.

Step 1: Data Preparation

As a first step in your Django assignment help, we will carefully load and preprocess the chest CT-scans dataset. If you already have a dataset at hand, great! Otherwise, consider using publicly available datasets such as the LIDC-IDRI dataset for your Django assignment help. Ensuring that our data is in optimal condition is crucial for building a robust deep learning model.

# Code Explanation:

# Replace 'your_data_folder' with the actual folder containing the CT-scan images.

# Ensure all images are of the same dimensions and preprocess them as required.

import os

import cv2

import numpy as np

data_folder = 'your_data_folder'

image_width, image_height = 256, 256

def load_data():

data = []

for filename in os.listdir(data_folder):

img = cv2.imread(os.path.join(data_folder, filename), cv2.IMREAD_GRAYSCALE)

img = cv2.resize(img, (image_width, image_height))


return np.array(data)

# Load and preprocess the data

X_train = load_data()

# ... other preprocessing steps (e.g., normalization, data augmentation)

Step 2: Deep Learning Model Creation

We take pride in our expertise in building powerful models. In this step, we will define the architecture of our deep learning model using TensorFlow and Keras. Leveraging Convolutional Neural Networks (CNNs), a popular choice for image analysis, we aim to deliver accurate and reliable predictions.

# Code Explanation:

from tensorflow.keras.models import Sequential

from tensorflow.keras.layers import Conv2D, MaxPooling2D, Flatten, Dense

def create_model():

model = Sequential()

model.add(Conv2D(32, (3, 3), activation='relu', input_shape=(image_width, image_height, 1)))

model.add(MaxPooling2D((2, 2)))

# Add more convolutional and pooling layers as needed


model.add(Dense(128, activation='relu'))

model.add(Dense(num_classes, activation='softmax'))

model.compile(optimizer='adam', loss='categorical_crossentropy', metrics=['accuracy'])

return model

# Create the deep learning model

model = create_model()

Step 3: Model Training

Our dedicated team understands the significance of model training. We will put our preprocessed dataset to good use and train the deep learning model with precision and care. The model's performance will be optimized during this phase to ensure accurate predictions.

# Code Explanation:

def train_model(X_train, y_train):

model.fit(X_train, y_train, epochs=10, batch_size=32, validation_split=0.2)

# Train the model

train_model(X_train, y_train)

Step 4: Django Setup

We believe in delivering comprehensive solutions. Setting up the Django project and creating a virtual environment are vital steps to ensure seamless integration and efficient workflow.

# Code Explanation:

# Create a Django project

django-admin startproject chest_ct_scan_project

# Navigate to the project directory

cd chest_ct_scan_project

# Create a virtual environment

python -m venv venv

# Activate the virtual environment

source venv/bin/activate

# Install Django and other required packages

pip install django

Step 5: Django Views

Our team of developers will create dynamic Django views to handle incoming HTTP requests. These views will serve as the backbone of our web application, enabling smooth communication between the user and the deep learning model.

# Code Explanation:

# Import required modules

from django.shortcuts import render

# Create a view for handling CT-scan upload and predictions

def upload_scan(request):

if request.method == 'POST':

# Process the uploaded file and pass it to the model for prediction

# Retrieve the prediction results

prediction = predict_ct_scan(uploaded_file)

return render(request, 'result.html', {'prediction': prediction})

return render(request, 'upload.html')

Step 6: Django Templates

We know the importance of an appealing and user-friendly interface. Our talented designers will craft visually appealing HTML templates to enhance the user experience while uploading and visualizing CT-scans.

< !DOCTYPE html > < html > < head > < title >Upload CT Scan< /title > < /head > < body > < h1 >Upload CT Scan< /h1 > < form method="post" enctype="multipart/form-data" > { % csrf_token % } < input type="file" name="ct_scan" > < input type="submit" value="Upload" > < /form > < /body > < /html > < !DOCTYPE html > < html > < head > < title >CT Scan Analysis Result< /title > < /head > < body > < h1 >CT Scan Analysis Result< /h1 > < p >Prediction: {{ prediction }}< /p > < /body > < /html >

Step 8: Model Integration

As experts in deep learning integration, we will seamlessly embed our trained model into the Django application. This integration will enable our web application to make predictions on the uploaded CT-scans promptly.

# Code Explanation:

# Import the model you created earlier and implement the prediction function

from your_model_file import model

def predict_ct_scan(uploaded_file):

# Preprocess the uploaded CT-scan file (e.g., convert to grayscale, resize)

# Perform the prediction using the model

# Return the prediction result

return prediction_result

Step 9: Display Results

User satisfaction is our top priority. We will ensure that the predictions obtained from the model are clearly displayed alongside the uploaded CT-scans, providing a comprehensive analysis.

# Code Explanation:

# In the upload_scan view, after getting the prediction result

def upload_scan(request):

# ... (previous code)

if request.method == 'POST':

# Process the uploaded file and pass it to the model for prediction

# Retrieve the prediction results

prediction = predict_ct_scan(uploaded_file)

return render(request, 'result.html', {'prediction': prediction})

return render(request, 'upload.html')

Step 10: Error Handling

A robust web application requires proper error handling. Our team will implement effective error handling mechanisms to address issues that may arise during the user's journey, ensuring a smooth experience.

# Code Explanation:

# In the upload_scan view, handle any potential errors during file upload or prediction

def upload_scan(request):

# ... (previous code)

if request.method == 'POST':


# Process the uploaded file and pass it to the model for prediction

# Retrieve the prediction results

prediction = predict_ct_scan(uploaded_file)

return render(request, 'result.html', {'prediction': prediction})

except Exception as e:

# Handle any exceptions (e.g., invalid file format, model errors)

error_message = str(e)

return render(request, 'error.html', {'error_message': error_message})

return render(request, 'upload.html')

Step 11: Deployment

Finally, we take care of the deployment process, making sure our web application is accessible to the public. With a fully deployed application, users can access the service with ease.

# Code Explanation:

# Depending on your chosen hosting service, deployment steps may vary.

# Here's a basic example using gunicorn and Nginx for deployment.

# Install gunicorn

pip install gunicorn

# Start the application with gunicorn

gunicorn chest_ct_scan_project.wsgi:application

# Set up Nginx to serve as a reverse proxy

# Install Nginx

sudo apt-get install nginx

# Create a new Nginx configuration file (e.g., /etc/nginx/sites-available/chest_ct_scan)

server {

isten 80;

server_name your_domain.com;

location / {


proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;



# Create a symbolic link to the sites-enabled directory

sudo ln -s /etc/nginx/sites-available/chest_ct_scan /etc/nginx/sites-enabled

# Restart Nginx

sudo service nginx restart
