Area measurement methods are used in various clinical practices such as wound management, dermatology, plastic and reconstructive surgery, burn units, surgical specialities and more. Traditional methods are often time-consuming or inaccurate. With this brief overview of existing methods, you will learn how imito solutions provide a safe, effective and fast alternative, directly on your smartphone.
Area measurements methods are mainly but not exclusively used in wound care to objectively document the lesion evolution; Is it growing bigger? How far does it extend? How fast is the size evolving? Does it shrink as expected in response to a specific treatment? For that different methods can be used and based on the excellent systematic review by Jørgensen LB et al.¹, we summarised the pros and cons for each of the two-dimensional measurement methods.
With imito digital planimetry, we are offering healthcare professionals a contactless, accurate, reliable and fast method to measure a surface area and all of this all directly on a smartphone!
The process is as follow:
During our validation tests, we came to following results:
Measurement quality depends on random errors such as environment (distance to marker or small tilt of the marker that makes it not exactly parallel to the picture), inter-operator variations (when tracing the wound boundaries on screen) and systematic errors (device camera optics distortion). Our measurement system in a wound care context has proven to have an excellent repeatability and accuracy in comparison to reference measurements performed with image J software (Digital imaging).
