3d anatomy prompt builder
Example session with this skill installed
Create a prompt for a 3D cross-section of the human heart at the level of the atrioventricular valves, showing a mitral valve prolapse for a medical student audience.
- Read your context and instructions
- Compiled the 3d anatomy prompt
- Generated the image
I have constructed a detailed prompt and visual specification for the atrioventricular cross-section, focusing on the mechanical pathology of the mitral valve.
Anatomical Brief
- Subject: Human Heart, cross-section at the AV plane.
- Pathology: Mitral valve prolapse (systolic bowing).
- Audience: Medical students (high anatomical detail required).
Visual Specification
| Structure | Tissue Appearance | Material Property |
|---|---|---|
| Myocardium | Deep red, fibrous texture | Low gloss, high subsurface scattering |
| Mitral Valve | Pearly white, semi-translucent | Thin membrane, slight sheen |
| Chordae Tendineae | Off-white, string-like | High tensile appearance, matte |
| Endocardium | Smooth, glossy pink | High specularity, wet look |
Generation Prompt
Micro-detailed 3D medical visualization of a human heart cross-section at the atrioventricular level, superior view looking down into the ventricles. The mitral valve is the focal point, exhibiting mid-systolic prolapse with the posterior leaflet billowing superiorly into the left atrium. Clearly define the annulus fibrosus, the tricuspid valve in the adjacent compartment, and the chordae tendineae. Tissues: myocardium shows distinct fiber orientation; valvular tissue is thin and semi-translucent pearly white. Lighting: bright clinical studio lighting, soft shadows to emphasize the depth of the ventricular chambers, rim lighting on the leaflet edges. Style: realistic 3D render, Octane render, high anatomical fidelity, 8k, neutral grey background.
Negative Prompt / Failure Exclusions
Avoid: merged valves, more than two mitral leaflets, generic red blobs for all tissue, glowing blood, disconnected chordae tendineae, text inside the image, cartoonish saturation, incorrect laterality of the heart chambers.
Label Plan
| Label Text | Anchor Point | Visual Style |
|---|---|---|
| Prolapsing Posterior Leaflet | Apex of the billowed tissue | Thin black leader line, sans-serif |
| Chordae Tendineae | Attachment point to papillary muscle | Thin black leader line |
| Left Ventricle | Central lumen of the left chamber | Callout box |
Next steps
- Copy the Generation Prompt into Midjourney v6 or DALL-E 3.
- Review the resulting image against a Netter’s Atlas for leaflet orientation.
- Apply the Label Plan in post-production for educational use.
Verification Notes
- Verify the degree of leaflet displacement against clinical grading for "prolapse" (typically >2mm).
- Ensure the relationship between the aorta and the mitral valve is preserved in the anterior view.

About this skill
The problem
General-purpose AI image generators often struggle with anatomical accuracy, producing merged structures, incorrect attachments, or generic "red" tissues. Developers building medical education or visualization tools need precise prompts that enforce spatial logic and clinical plausibility.
What it does
- Converts anatomical subjects into highly detailed prompts for 3D renders, medical illustrations, or surgical visualizations.
- Enforces precise spatial relationships using standard anatomical directional terms like proximal, distal, and contralateral.
- Maps specific tissue appearances to materials, defining subsurface scattering for bone, cartilage, fascia, and vascularity.
- Structures prompt components for sections, transparent layers, or exploded views to ensure interior structures remain visible.
- Generates comprehensive failure exclusions to prevent common AI hallucinations like impossible branching or distorted proportions.
Why this beats prompting it yourself
Writing prompts that capture the complexity of human anatomy requires deep domain knowledge and specific technical vocabulary. This skill automates the translation of a simple subject into a multi-layered technical specification, ensuring that camera angles, lighting, and tissue properties are optimized for educational clarity rather than just aesthetics.
Use cases
- Generating high-fidelity 3D assets for medical training simulations and AR/VR apps.
- Creating labeled anatomical diagrams for patient education materials and textbooks.
- Visualizing specific surgical approaches or pathological states for clinical presentations.
- Building datasets of anatomically plausible imagery for machine learning training.
Known limitations
This skill generates prompts for visualization purposes and does not provide clinical diagnoses or treatment advice. All outputs must be verified against authoritative medical references.
