thermal image of patient's hands

Bath’s Royal National Hospital for Rheumatic Diseases has updated its thermal imaging camera to enable better evaluation of patients who may have Raynaud’s disease or chronic pain conditions. Raynaud’s disease can be a cause of cold or numb fingers, whilst in chronic pain the affected limb can become cold.

The new thermal imaging camera, which displays heat as a visual image, is from Focus 2000 Infrared Ltd's Thermal Vision Research team. A research grant from the Raynaud’s and Scleroderma Association enabled the purchase of this camera which will be used extensively for research and clinical assessment. Whilst the hospital’s previous thermal imaging camera functioned only over limited temperature range and took single images, the new camera and software system can record and display sequences of thermal images over a wider temperature range with improved precision.

As Darren Hart, Clinical Scientist explains; “It can be difficult to quantify a patient’s sensation of coldness. The Thermal imaging camera allows accurate measurement of temperature differences between limbs or the severity of cold fingers. When assessing the response of a patient’s hands to a cold stimulation, we will now be able to record the whole rewarming sequence so that we can replay and analyse it in much greater detail. Ultimately this will help us to identify patterns that may provide improved diagnosis in future.”

The RNHRD prides itself on a reputation for clinical and research excellence, and is known internationally within the specialist fields of rheumatology and pain management. Previous research studies have used the RNHRD’s thermal imaging facilities to further the understanding of conditions within these specialties and identify the best possible treatment for patients affected by them. The new camera system will help the RNHRD continue to lead and participate in future research involving the latest developments in clinical thermal imaging.
