3-D measurement device shows promise
A new 3-D wound measurement device was highly reliable when measuring a range of wound sizes and types, according to a study published in Wounds.
Researchers from the Center for Wound Healing at Georgetown University Hospital studied a camera developed by inSight to determine if it could beat standard measurement tools such as rulers and planimetry.
The device combines the iPad with infrared-based structure sensing and computer vision to delineate wound borders. Two raters used it to assess 45 wounds for length, width, area, depth and volume. Wounds also were measured manually.
Though depth was an issue, the device accurately measured volume and the measurements correlated with scaled photography. The researchers said it was less time-consuming and invasive than other methods.
“Clinicians must be able to track wound progression over time to determine treatment effectiveness and the necessity for alternative interventions,” wrote Ersilia L. Anghel, Limb Salvage Research Fellow at Georgetown.
The study found the device was capable of doing just that, despite some limitations with lighting and orientation.
