Introduction

Thermal imaging is thought to have potential in burn depth assessment. FLIR One is a miniature thermal imaging camera, which is mountable to a smartphone and ready to use with the corresponding free FLIR One mobile app. There is no need for any operator training and images are taken similar to that of taking photos using a smart phone. The accompanying FLIR One app merges the digital with thermal images, producing an image with corresponding colour palate with a matching range of temperature.

This study aims to assess the practicality of FLIR One in clinical application and to compare against moor LDLS-BI in the assessment of burn depth in adults.

Methodology

Adult burn wounds presenting within 48 hours of injury of total body surface area of less than 10% were included for assessment. Patients were divided into groups according to wound healing potential of a) less than 14 days, b) between 14 and 21 days and c) above 21 days. We correlated the healing potential of FLIR One against the moor LDLS-BI.

Results

The incorporation of FLIR One into service provision was easy as the device was portable and no prior training was required. There was a learning curve for the use of the accompanying mobile app and the interpretation of images. The predicted healing potential of burn wound using the FLIR One correlated well and its accuracy comparable to moor LDLS-BI.

Discussion

FLIR One signifies the beginning of ‘real-time’ thermal imaging. Our experience with the device was positive.
