MEDICAL INFRARED THERMAL IMAGING NEWS
- 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.

The aim of the journal is to provide a vehicle relevant to surgeons, biomedical engineers, imaging specialists, materials scientists, rehabilitation personnel and all those with an ... 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 b Bolton Primary Care Trust, Lever Chambers, Bolton, United Kingdom c Physiotherapy Department, Satakunta Applied University, Pori, Finland Received 25 June 2009; revised 8 October 2009; accepted 9 October 2009. Available online 2 November 2009. Online Training Course Offered .... Those interested in learning more about thermal imaging can now take the online training course being offered in clinical infrared. This program provides a good overview of the science and technology for use in the health and scientific fields. Information is provided to assist with setting up a thermal imaging center along with suggested input forms and other materials of relevance for good procedure and understanding of the technology. Visit the training link on the thermology website for further information on this program. http://www.thermology.com/onlinecourse.html Classes in Tampa Teletherm is providing a series of upcoming training classes on infrared thermal imaging scheduled in Tampa, Florida. They are held at facilities in the exciting and historic Ybor City district of Tampa. These are two day programs with hands-on lab experience with the thermal imaging equipment. The classes provide comprehensive training sessions on thermal imaging in the clinical and scientific environment. These classes do fill up fast and space is limited. Personalized instruction sessions are provided and assist both the novice and the knowledgeable. http://www.thermology.com/training.html T4 Compatibility with Windows 7 OS The latest T4 infrared thermal imagers from ASI are fully compatible with the Windows 7 operating system. With the latest laptops incorporating webcam and wireless technology, the operating system has helped enhance the versatility of these imaging systems. Easy sharing of image capture procedures, image files and the facilitating of the training / support systems, the new units provide the infrared instruments with a lot of power and flexibility. The T4 imagers are well suited to be remotely operated through networks involved in telemedicine. T4 Systems Recommended Text - Biomedical Engineering New chapters (~150 pages) on infrared imaging can be found in the latest (3rd) edition of "The Biomedical Engineering Handbook; Medical Devices and Systems"; CRC, Taylor and Francis. Ed. Joseph D. Bronzino; ISBN 0-8493-2122-0. This is the foremost text in biomedical engineering, and shows where medical thermography stands today. |
