Imaging technology continues to evolve.
A hundred years ago, X-rays offered the most dramatic step change in diagnostics and treatment. Since then, new technologies have taken its place, each one further enhancing a physician's ability to visualize disease and illuminating a clear pathway to improved health.
For venous insufficiency, thermography is the new frontrunner.
Thermography at work
While thermographic instruments measure absolute temperature, the beauty of clinical thermography is the visualization of temperature differences and their implication. Our thermography solution takes advantage of a phenomenon unique to venous insufficiency.
As a result of valve failure within a vein, blood is refluxed or back flows. This reflux is most evident while standing and is a different temperature than the surrounding area.
The refluxed blood has a distinctive "heat signature" that not only indicates diseased veins, but literally illustrates a roadmap for the physician to pinpoint the source of the venous disease.
Normal veins maintain a temperature equivalent to surrounding tissue and the skin, making them invisible to our device.
Thermography in practice
The optimal use of thermography is as an adjunct to ultrasound. Thermography provides doctors, technologists, and very importantly, patients, with a clear visualization of incompetent veins.
Being able to see refluxing veins may accelerate both the patient understanding of the underlying pathology and the technologists efforts in both mapping the leg and confirming with ultrasound.
Because of its ease-of-use and efficiency, our research suggests more thorough mapping is possible, in turn laying the foundation for more appropriate procedures and ultimately increasing patient satisfaction.
