Setting Up AI Features
Kantrad can use artificial intelligence to help you analyse images, draft report sections, and answer questions about your cases. The AI runs on your own computer, so patient data never leaves your machine.
Note: AI features unlock automatically once you’ve activated Kantrad through the email-verify step in the Welcome wizard (Getting Started). No separate licence key to enter - your account is the licence.
What Can AI Do?
Once set up, AI can help you with three things:
- Image analysis — The AI looks at a medical image and describes what it sees.
- Report assistance — The AI can draft findings and impressions based on what it observes.
- Chat assistant — You can ask the AI questions about a case, request differential diagnoses, or have it summarise your findings.
Setting Up AI Step by Step
The AI engine and the recommended Kantrad 4B vision model are downloaded automatically the first time you launch Kantrad (the Setup step of the Welcome wizard). For most users, that’s all they need to do - AI is ready to use as soon as the wizard finishes.
To switch models or download additional ones manually:
- Open Settings, then go to AI Configuration.
- Confirm the inference engine is installed (this is the small ~20–50 MB runtime that lets the AI models execute).
- Choose a model and click Download next to it.
- Once the download is complete, click Start.
Choosing an AI Model
Different models have different strengths. Here is a guide to help you choose:
| Model | Download Size | Memory Needed | Best For |
|---|---|---|---|
| Kantrad 4B | 2.5 GB | 4 GB | Medical imaging - recommended for most users. Pre-trained on radiology, pathology, and dermatology images |
| Kantrad v1.5 | 4.4 GB | 6 GB | Proven quality, good all-round performance |
| Kantrad v1.5 Pro | 7.9 GB | 10 GB | Higher accuracy, but needs a powerful computer |
Tip: If your computer has 8 GB of memory or less, stick with Kantrad 4B. If you have 16 GB or more, you can try Kantrad v1.5 Pro for potentially better results on complex cases.
Adjusting AI Performance
In the AI Configuration settings, you can fine-tune two things:
- GPU Layers — This controls how much of the AI model runs on your graphics card. Higher numbers mean faster results but use more graphics memory. If you are not sure, leave this at the default.
- Context Size — This determines how much text the AI can consider at once. The default works well for most situations.
Using the AI Chat
The AI Chat tab gives you a conversation-style assistant. You can type questions or use the quick action buttons:
- Analyse Frame — Sends the current image to the AI for analysis.
- Segment — Highlights organs and structures in the image (requires segmentation to be set up — see the Segmentation guide).
- Draft Impression — Creates a summary based on your findings.
- Summarise — Condenses your findings into bullet points.
- Differentials — Suggests possible diagnoses to consider.
Privacy
All AI processing happens locally on your computer. No patient data, images, or report content is sent to external servers. The AI engine runs as a local process managed by Kantrad.
