Handheld 3D imaging system for medical applications

Qt is an established user interface (UI) and cross-platform application framework used in the automotive, medical, aerospace and industrial automation industries, among a number of industries. Digia, Qt Commercial is a pioneer in the commercial development, support, services and exclusive licensor of Qt for desktop and embedded development.

According to Eykona they identified a need for the accurate measurement and clinical characterisation of hard-to-heal wounds such as diabetic and pressure ulcers. Existing techniques estimated the volume of wounds – the change of which is an important indicator of the healing process – by multiplying an area estimate with a depth measurement obtained from a probe. This method is both inaccurate and difficult to replicate. Eykona used patented technology, based on research at the University of Oxford, to develop a handheld imaging system that produces a full colour 3D model of a wound that can be stored in the patient’s treatment record and shared to enable remote assessment.

Having evaluated a number of graphical UI and application frameworks, Eykona selected Qt Commercial because of  its cross-platform support; the products widespread adoption, meaning that developers were readily available; and a highly positive experience during evaluation. The company chose to work with Qt Commercial, preferring the support and licensing benefits to the open source route. However, the developers still made extensive use of the online knowledge base of the wider Qt community.

Commenting on his team’s experience with Qt Commercial, Eykona CTO Dr. James Paterson said: “It is more flexible and has better support. Qt Commercial’s cross-platform support was especially valuable. It allowed us to develop our embedded Linux application before the hardware platform was available – we simply developed under Windows and then directly compiled for the Linux platform. Taking an alternative route we would have had to of added 6-9 months to our development time to initial release.”
