4DEYE Dx

See the dysfunction

before it becomes damage

4DEYE Dx

The only solution for AI-based

joint dysfunction screening

4DEYE Dx

AI MSK Assessment System

4DEYE Dx detects joint dysfunction and movement abnormalities with precision—before pain or structural damage appears. Its 3D analysis, powered by five multi-view cameras, ensures distortion-free assessment and medical-grade reliability. 

*Accurate 3D motion screening with AI requires spatial coverage across width, height, and depth. 

Key Features 

From Precise Analysis to

Personalized Exercise

AI Joint Detection 

Korea’s first AI to automatically detect joint dysfunction with XYZ reconstruction. 

Joint Function Test(Movn't Impairments) 

Accurately evaluates the actual range of motion through precise 3D analysis.  

3D Detailed Posture Analysis 

Visualizes body misalignment and posture abnormalities using multi-view 3D imaging. 

Personalized Exercise 

AI recommends rehab programs tailored to each individual’s condition.

AI Musculoskeletal Screening System

4DEYE Dx detects joint dysfunction and abnormal movement patterns - before pain or structural damage appears.

Specifications & Installation 

Five sensors. One 4D view of the body.

Multi-view 3D capture eliminates perspective distortion,

delivering measurements you can hold to a clinical standard.

*Accurate 3D motion screening with AI requires spatial coverage across width, height, and depth.

Core Capabilities 

From precision analysis 

to a personalized program.

Automated joint dysfunction detection 

The first AI algorithm in Korea to detect joint dysfunction automatically — across all three axes (X, Y, Z). 

Range of motion assessment 

3D analysis measures how far the joint actually moves, not how far it's assumed to. 

3D posture analysis 

Multi-view capture makes asymmetry and postural deviation objectively visible. 

Automated exercise programming 

AI converts screening data into a rehab program matched to the individual patient. 

Screening Workflow

A structured AI assessment

and a rehab program 

you can prescribe from it.
