Distinguishing between medical and industrial
- Thermal Imaging Systems design.
There has always been a discussion about thermal imaging systems and the requirements for protocol as recommended by various professional groups in the field.  When discussing protocol, it's important to note that this is a user defined safety net that's created to assist the health and scientific field, in this case, to eliminate technician error in the process of capturing a thermal image.  It's very much subject to change as technology evolves and processes become redundant.  The instrument used for medical applications is going to have very different requirements than that being used in the industrial or military sector.  With the explosion of infrared thermal imagers on the market for all types of applications, the medical or health care area remains very specific with its requirements for obtaining high quality and consistent thermograms.  Imaging environment controls, patient or subject preparation, capturing capabilities, technician training, and image processing features are all factors to be considered with usage of an infrared thermal imaging system, and vary greatly between medical and industrial infrared imagers.  The knowledge level required for operating controls reliably at the time of imaging is also a factor.  This is particularly relevant when taking images over time and making comparisons.  In the health care field, this is important to make appropriate evaluations that guide the diagnostic process, and not leave much room for error.  For comparisons between systems, make sure to visit:  medicalvsindustrial

Abnormal reactions to environmental cold have been observed in some patients with Anterior Knee Pain (AKP). The aims of this study were to investigate whether palpation of the knee could classify patients into those with and those without cold knees; whether this classification could be objectively validated using thermal imaging; whether the cold and not cold knee groups varied in response to a cold stress test and in patient-reported measures. Fifty eight patients were recruited; palpation classified them into cold and not cold groups. Twenty-one (36%) patients were classified as having a cold knee by palpation: fourteen (36%) females and seven males (37%). Preliminary analysis suggested gender might be an effect modifier and the number of men was small, therefore the analysis focussed on females. Women with cold knees had a significantly smaller patellar skin fold, lower levels of activity and worse scores on the MFIQ, there also appeared to be an association with a traumatic onset. Women with cold knees were more likely to report cold weather affected their knees and they preferred a hot water bottle compared to an ice-pack on their knee; there was also a trend towards having to wear extra tights/long johns in the winter. This study has helped to define a clinical profile for a group of females with AKP and cold knees. This group appears to demonstrate a mild form of Reflex Sympathetic Dystrophy.School of Public Health and Clinical Sciences, University of Central Lancashire, Preston, Lancashire, United Kingdom
