How DermVision 3D Works

From patient seating to AI-generated clinical report — the entire process takes under 60 seconds, delivering 38 quantified skin dimensions.

Patient Positioning

Patient places face in the ergonomic chin rest with adjustable forehead stabiliser. The technician initiates the scan from the touchscreen console.

12-Channel Spectral Imaging

12 spectral channels in 8 seconds — RGB, UV, Cross-Polarised, Parallel-Polarised, Brown, Red, Wood's Lamp, NIR 850nm. Each reveals a different skin layer.

RGBUV 365nmCPLNIR 850nm

3D Structured Light Mapping

Binocular grating + ToF sensor fusion creates a precise 3D mesh with ~250,000 vertices at 0.15mm resolution, colour-mapped for photorealistic rendering.

⚠️ The Critical Problem

The Dark Skin AI Gap

Every global skin analyzer is calibrated for Caucasian and East Asian skin. Indian skin (FST III–VI) shows a documented AUROC drop from 0.89 to 0.82 on existing devices. Prana fixes this at the hardware, optics, and AI training level.

★ Featured Research Prana DermVision 3D — The Optical Bias Problem

🎬 The Optical Bias: Why "More Data" Won't Fix Medical AI

A deep-dive documentary exploring why the standard industry response of "just collect more diverse training data" fundamentally fails to address the optical physics problem in dermatology AI. The video explains how melanin absorbs and scatters light differently across Fitzpatrick III–VI skin types, creating a hardware-level bias that no amount of software post-processing can overcome — and how Prana DermVision 3D solves this with FST-adaptive exposure, NIR 850nm imaging, and India-specific spectral calibration.

Optical Physics AI Bias DermVision 3D Melanin-Adaptive FST III–VI
Dark Skin AI Accuracy Gap

Why Global Devices Fail on Indian Skin

  • Melanin Saturation: Higher melanin in FST IV–VI absorbs more UV and visible light, reducing signal-to-noise ratio in standard imaging
  • Training Data Bias: Global AI models trained on TCGA/Western datasets show measurable performance drops on Indian tissue samples
  • No India-Specific Conditions: Melasma depth, periorbital darkening types, vitiligo VASI — none classified in any global analyzer
  • Fixed Calibration: Single exposure settings optimised for light skin under-expose dark skin, losing sub-surface detail

How Prana Solves This

FST-adaptive exposure per channel • India-specific AI training data (8,000+ melasma cases from AIIMS Delhi + MSR) • NIR 850nm channel for vascular vs pigmentary differentiation on dark skin • Hardware-level photometric recalibration for Fitzpatrick III–VI

AI Analysis Engine

38-Dimension Skin Analysis Matrix

The AI engine analyses both 2D spectral images and the 3D mesh to generate quantified scores across 6 categories — the most comprehensive analysis available for Indian skin.

38 Skin Analysis Dimensions
Aging 8

Wrinkle depth, fine lines, crow's feet, forehead lines, nasolabial folds, marionette lines, glabellar lines, skin laxity — per-zone scoring with temporal tracking

Pigmentation 10

Spots, freckles, UV damage, melasma depth (India-exclusive), PIH grading, hyperpigmentation zone mapping, colour evenness — 6 dimensions are India-exclusive

Texture & Pore 7

Pore size distribution, sebum level, blackheads, surface roughness, texture uniformity, skin smoothness index, comedone detection

Vascularity 7

Redness zones, rosacea grading, spider veins, erythema index, sensitivity score, flushing pattern, vascular lesion mapping using Red + CPL channels

Moisture 3

Moisture balance zone map (Corneometer-equivalent), oil-moisture ratio (T-zone vs U-zone), dehydration surface index from NIR light scatter

3D Morphology 3

Facial symmetry score (106-landmark analysis), Golden Ratio indices (horizontal thirds + vertical fifths), volume delta map for filler tracking

🇮🇳 India-Exclusive Innovation

4 India-Exclusive AI Modules

These modules address India's most prevalent skin conditions — conditions that no global device (VISIA, Observ, Canfield VECTRA) has any capability to detect or classify.

India-Exclusive AI Modules

Melasma Depth Classifier

Classifies epidermal vs dermal vs mixed melasma using UV fluorescence + Brown channel analysis. Treatment depends entirely on depth — yet no device automates this.
