01
Thermal foot capture
A clinician captures a thermal image of a patient’s feet using a smartphone-connected thermal camera. This non-invasive scan takes less than 30 seconds and can be done during routine visits.
02
AI-based analysis
PETRA’s AI isolates the foot, removes background noise, and compares left-to-right temperature patterns. A ≥2.2°C asymmetry is automatically flagged as clinically significant.
03
Clinical risk output
PETRA generates heat maps and risk indicators that clinicians can use to determine whether offloading, monitoring, or intervention is needed before ulcers develop.
