What is Pixacare's Artificial Intelligence used for?
Pixacare's Artificial Intelligence (AI) allows for automatically measure and analyze wounds from calibrated photographs.
It standardizes clinical observations, improves measurement reliability and helps caregivers to objectively assess wound healing progression.
How does Pixacare's AI work?
To enable automatic measurement, simply place a calibration sticker on the healthy skin, in the immediate vicinity of the wound, then take one or more photos.
The Pixacare interface displays visual indicators :
- If the signals are green, the photo is correctly calibrated.
- If they are red, it needs to be retaken (the sticker is not in the correct plane and the measurement would be inaccurate).
The AI automatically outlines the wound, calculates its surface area in cm², then analyzes the tissues (granulation, fibrin, necrosis) and indicates the distribution percentages.
How to get calibration stickers?
The calibration stickers are provided automatically upon subscription to a paid plan (Pro, Institution, or Research).
When they run out, simply contact customer support to receive new ones. A replenishment is shipped within 48 business hours.
For Research plans, stickers are considered a consumable and can be provided as an add-on, according to the terms stipulated in the contract.
Does Pixacare's AI provide a diagnosis?
No. Artificial intelligence only provides objective measurements and visual analyses. The clinical decision always remains under the responsibility of the healthcare professional.
How does AI contribute to clinical research?
Pixacare's AI standardizes measurements and creates a true gold standard for clinical research, facilitating the comparison of results between teams and studies.
This allows for the production of reliable, traceable, and auditable data, usable in projects RWE or the multicenter clinical trials.
Has the AI's performance been clinically validated?
Yes. The artificial intelligence modules WoundTrack (semi-automated) and WoundSize (automated) have been validated in the PIXAIRE1 study, conducted at the Haguenau Hospital (vascular surgery department).
Les résultats, en attente de publication dans l’International Wound Journal, confirment la très forte corrélation entre les mesures Pixacare et la digitized planimetry, the reference method.
How is Pixacare's AI developed?
Pixacare's algorithms are trained using thousands of images annotated by hospital experts and clinically validated.
Development is carried out within an ISO 13485 certified quality system, ensuring rigor, traceability, and safety.
Is the calibration technology patented?
Yes. The calibration sticker is based on a patented technology developed by Pixacare.
This device automatically adjusts the colors, angles, and distances, ensuring reliable and reproducible measurements, regardless of the phone brand or the lighting conditions.
What are Pixacare AI's certifications?
The artificial intelligence module is undergoing CE Class IIa certification as part of the European Medical Device Regulation (MDR).
It will be registered as Digital Medical Device (DMD) upon regulatory approval, under the name WoundTrack II.
