PainScan is a digital health platform that makes chronic pain visible in 3D so it can be properly diagnosed and treated.

PainScan Exams capture the patient’s pain picture more clearly and visibly than any verbal explanation or the 0-10 pain scale ever could.

With PainScan, patients no longer need to worry if their healthcare providers believe the pain they are experiencing is real. Instead, their healthcare team can focus on diagnosing those underlying conditions that would likely produce the patterns seen on the patient’s PainScan Report.

PainScan has a Mission to make pain visible and validated, and to provide clarity to patients and their healthcare teams for successful outcomes.

Our Vision is that PainScan Exams are essential tools for patients to understand and take control of their own health, and that physicians can rely on PainScan to document, diagnose and treat pain.

The PainScan system merges computer vision, machine learning, and the physician exam to produce a vivid, accurate representation of pain patterns and intensity.

PainScan Origin

PainScan was envisioned by Dr. Andru Zeller based on his experiences with patients in his Albuquerque, New Mexico clinics. These patients did not want opiate medications for their pain, rather they needed answers and effective solutions so they could get back to work to care for their families.

Diagnostic imaging often fails to pinpoint the reasons for chronic pain, so Dr. Zeller established a physical exam method that consistently provided more comprehensive clinical information. While effective, the method was time consuming, and challenging to document without being automated. Dr. Zeller was then determined to create an automated system to produce a 3D pain map for his patients.

PainScan was created from a passion to serve and a focus on efficiency.
