3D imaging device enables dramatic improvement in wound care
13 November 2012
Oxford company Eykona Medical has developed an imaging
device that can automatically measure the characteristics of diabetic
wounds in 3D, faster and with greater consistency and accuracy than
current manual techniques.
The cost of diabetic ulceration and amputation in the UK is about
£650m annually, affecting over 60,000 people. The new device
replaces current wound analysis techniques, including naked-eye
assessment, tracing paper and pencil, dipstick depth measurement and
relatively invasive resin casts, and observations recorded on
hand-written paper notes.
Developed over eight years, starting at Oxford University, the
Eykona device consists of two cameras and four high powered flash
units in a light, mobile and easy-to-use unit. Small sterile
‘targets’ are used to set the focus and position of the camera. This
eliminates inconsistency between images and can be used by any
health care professional without the need for extensive or costly

The Eykona system builds a 3D image and utilises specially
designed software to measure size, depth and skin tone with
precision and detail at the sub-millimetre level. It creates a
detailed 3D model of any wound or scar from which accurate
measurements of distance, area, colour, width or volume can be made.
Using rendering software, the 3D model can be assessed from all
angles and shared with other clinicians through server or
cloud-based hosting of the data.
Changes in the wound can be recorded over time, giving valuable
information on the status of the tissues in the wound bed.
Clinicians can then use definitive evidence to understand if and how
the wound is healing, allowing them to adjust the treatment plan
Dr James Paterson, one of the inventors of the Eykona system
commented, “One of the risks of inaccurate measurement and treatment
of diabetic wounds is amputation, with 50% of people who have a
major amputations dying within two years. Through the use of the
Eykona system, many of these amputations could be avoided through
more precise, efficient and effective care resulting from accurate
“By replacing archaic, basic and expensive processes, Eykona is
not just saving time and money, but lives. It means more
measurements can be taken, in less time, by any number of healthcare
professionals. They can then be shared with clinicians and
specialists anywhere in the world if needed, improving the standard
of care and reducing travel costs.”
Early adopters include the Royal Centre for Defence Medicine,
which is currently using the device in the field to help treat the
wounds of soldiers in Afghanistan as well as mapping impacts on body
armour to improve research and development.
The device is currently being used by a small number of NHS
trusts, and is expected to receive full approval for medical use
later this year.
