Replay AI for Building a Medical Imaging UI from Video

TL;DR: Replay AI uses video analysis and behavior-driven reconstruction to generate a functional medical imaging UI, saving development time and ensuring user-centric design.

The Challenge: Building Intuitive Medical Imaging Interfaces#

Medical imaging interfaces are notoriously complex. Radiologists and technicians need access to a wealth of information, tools for manipulation, and clear visualization, all within a single, intuitive UI. Traditionally, building these interfaces is a time-consuming process, requiring extensive collaboration between developers, medical professionals, and UI/UX designers. Iterating on prototypes based on user feedback can be a slow and costly endeavor. The result is often clunky, inefficient software that hinders, rather than helps, the diagnostic process.

Enter the era of AI-powered development. Screenshot-to-code tools offer a tantalizing glimpse of the future, but fall short when faced with the dynamic nature of user interaction and the underlying logic of complex applications. They only capture static images, missing the critical context of how a user interacts with the interface.

Replay AI addresses this gap by focusing on behavior-driven reconstruction. Instead of relying on static screenshots, Replay analyzes video recordings of users interacting with existing (or even mock) medical imaging workflows. By understanding the user's intent, Replay can generate a functional UI that accurately reflects the desired behavior.

Replay AI: Behavior-Driven Reconstruction in Action#

Replay AI leverages the power of Gemini to understand the nuances of user behavior within the recorded video. It goes beyond pixel-perfect replication, analyzing the sequence of actions, button clicks, data inputs, and overall workflow to reconstruct a functional and adaptable UI. This approach unlocks a new level of efficiency and accuracy in medical imaging UI development.

Key Features for Medical Imaging UI Development#

Replay AI offers several key features tailored to the specific needs of medical imaging application development:

• •Multi-Page Generation: Complex workflows often span multiple screens. Replay seamlessly reconstructs multi-page applications, capturing the flow of information between different views.
• •Supabase Integration: Medical imaging data is often stored in secure databases. Replay integrates with Supabase to allow developers to connect the generated UI to existing data sources.
• •Style Injection: Maintain a consistent look and feel across your application. Replay allows you to inject custom CSS or use existing style libraries to ensure visual coherence.
• •Product Flow Maps: Understand the user journey at a glance. Replay generates visual flow maps that illustrate the sequence of actions and data transformations within the application.

How Replay Differs from Screenshot-to-Code Tools#

The difference between Replay and traditional screenshot-to-code tools is stark. Here’s a comparison:

Replay understands what the user is trying to achieve, not just what they see. This allows for the generation of more intelligent, user-friendly, and functional UIs.

Building a Medical Imaging UI with Replay: A Step-by-Step Guide#

Let's walk through the process of using Replay to build a basic medical imaging UI. We'll focus on a simplified workflow: uploading a DICOM image, adjusting contrast, and viewing the image.

Step 1: Capture the Workflow#

Record a video of a medical professional interacting with an existing medical imaging application or a mock-up. The video should clearly demonstrate the desired workflow:

1. •Uploading a DICOM image.
2. •Adjusting contrast and brightness using sliders.
3. •Zooming and panning the image.
4. •Saving the adjusted image.

💡 Pro Tip: Ensure the video is clear and well-lit. Speak clearly and explain your actions to provide additional context for Replay. The more detail you provide, the better the generated code will be.

Step 2: Upload to Replay#

Upload the video to the Replay platform. Replay will automatically analyze the video and identify the key UI elements, actions, and data flows.

Step 3: Review and Refine#

Once the analysis is complete, Replay will present a draft of the reconstructed UI. Review the generated code and make any necessary adjustments. You can refine the UI by:

• •Modifying the generated code directly.
• •Adding custom components or logic.
• •Adjusting the styling using CSS or a style library.

📝 Note: Replay's AI is constantly learning and improving. The more feedback you provide, the better it will become at accurately reconstructing UIs.

Step 4: Integrate with Supabase#

Connect the generated UI to your Supabase database to enable data persistence and retrieval. This allows you to store and manage medical images and associated metadata.

Step 5: Deploy and Iterate#

Deploy the generated UI and gather feedback from medical professionals. Use this feedback to further refine the UI and improve its usability. Replay makes it easy to iterate on your designs and quickly deploy updated versions.

Code Example: Adjusting Contrast#

Here's an example of the code Replay might generate for adjusting the contrast of a medical image:

typescript
// Contrast Adjustment Component
import React, { useState } from 'react';

interface ContrastProps {
  onContrastChange: (value: number) => void;
}

const ContrastSlider: React.FC<ContrastProps> = ({ onContrastChange }) => {
  const [contrast, setContrast] = useState(100);

  const handleContrastChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    const newValue = parseInt(event.target.value, 10);
    setContrast(newValue);
    onContrastChange(newValue);
  };

  return (
    <div>
      <label htmlFor="contrast">Contrast:</label>
      <input
        type="range"
        id="contrast"
        min="0"
        max="200"
        value={contrast}
        onChange={handleContrastChange}
      />
      <span>{contrast}%</span>
    </div>
  );
};

export default ContrastSlider;

// Usage example:
// <ContrastSlider onContrastChange={(value) => { /* Apply contrast adjustment to the image */ }} />

This code snippet demonstrates how Replay can generate functional components with event handlers and state management. The

component allows users to adjust the contrast of the image using a slider. The prop allows you to apply the contrast adjustment to the image data.

Code Example: DICOM Image Upload#

Here's another example showing how Replay helps with DICOM image upload:

javascript
// DICOM Image Upload Component
import React, { useState } from 'react';

const DICOMUploader = () => {
  const [selectedFile, setSelectedFile] = useState(null);

  const handleFileChange = (event) => {
    setSelectedFile(event.target.files[0]);
  };

  const handleUpload = async () => {
    if (!selectedFile) {
      alert('Please select a file');
      return;
    }

    const formData = new FormData();
    formData.append('dicomImage', selectedFile);

    try {
      const response = await fetch('/api/upload', { // Replace with your API endpoint
        method: 'POST',
        body: formData,
      });

      if (response.ok) {
        alert('Image uploaded successfully!');
      } else {
        alert('Image upload failed.');
      }
    } catch (error) {
      console.error('Error uploading image:', error);
      alert('An error occurred during upload.');
    }
  };

  return (
    <div>
      <input type="file" accept=".dcm" onChange={handleFileChange} />
      <button onClick={handleUpload} disabled={!selectedFile}>Upload</button>
    </div>
  );
};

export default DICOMUploader;

This code provides a basic file upload component, handling the selection and upload of DICOM images. Replay automatically generates the necessary event handlers and API calls based on the observed user behavior in the video.

⚠️ Warning: Remember to implement proper error handling and security measures when handling sensitive medical data.
