Provide information on thermal imaging – noting the non-invasive aspect. Advise to wear loose fitting garments on day of test. Try not to use creams on body Avoid getting too much sun Note any moles, scars etc. Try to avoid smoking Avoid strong exercise or physiotherapy on day of exam.
Recommendations to subject prior to test – use handout sheet – Thermal imaging is a very efficient and easy test when conducted properly. Note any drug therapy Have a mat for feet & place for jewelry Avoid chairs for back exams Standardize distances - Use a measuring tape and make markings. Record settings on patient chart for repeat studies on same subject.
Wavelength for clinical infrared imaging 8 -12 micron is preferable NEDT – noise equivalent Delta T – temperature differences Radiometric aspect – be able to measure specific temperatures on the image. Cooling methods – LN 2 is the most stable at temperature, does not vary – low noise – the gold standard – quicker to temperature – excellent for clinical. Thermal range – physiological – for clinical applications, the operator should not have to worry about pre-setting this range.
Be able to repeat exact elements Subject should not be sweating or overly cold. Delayed equilibration protocol is debatable in the medical literature. Room Temperature factors - Keep room comfortable for patient. No abnormal drafts. For sympathetic/vascular – 22 -24 Celsius to avoid reflex vasoconstriction. Lighting issues Avoid incandescent lighting in test area or direct sunlight. Have a wall thermometer – document temperature at time of test. Time of Day factors – be aware of influence of the Circadian Rhythm. Most stable period of day is between 9 and 11: 30 a. m.
