3D camera for monitoring ulcer healing

3D billede af fod

Diabetes is a disease, which can cause deep foot ulcers that take a lot of time and resources to heal. Diabetic foot ulcers are among the most serious and cost-consuming complications in relation to diabetes.

Numerous studies have shown that the size of the ulcers, including the depth, is one of the essential factors in delayed healing.

In the Region of Southern Denmark, a nurse is able to treat the patients at home, and therefore they will avoid many trips to the hospital. With the aid of a 3D scanner, a specialist can monitor and guide the treatment.


The PhD project assessed the ulcer measurements by using the 3D scanner and compared these measurements with standard measuring methods (2D method and gel injection).

The aim of the project was to clarify if the 3D pictures of ulcers could provide more accurate measures to clarify the basis for lacking ulcer healing. The future vision is that the 3D scanner will be useable in a telemedical context in the primary sector and also at the hospital’s specialised centres for ulcer treatment.


The project developed a 3D camera named 3D-Wound Assessment Monitor (WAM) camera, which is able to assess wound characteristics as well as to measure wound size in 3D. The camera is an accurate and reliable method for measuring wounds in three dimensions. Furthermore, the 3D camera is appropriate for monitoring wound healing of diabetic foot ulcers particularly in wounds with an area above five cm2.

The changes in 3D area measurements were significantly larger compared to 2D area measurements. This can be explained by the fact that the changes in 2D area (surface area) is only an expression of the wound healing from the surface of the wound, whereas the changes in 3D area is an expression of both the wound healing from the wound bed and the surface of the wound. However, in small wounds with an area below five cm2, the difference between the changes in the 2D area and 3D area measurements were very small due to the wounds are often shallow.
