Active infrared thermography is a fast, painless, noncontact, and noninvasive imaging method, complementary to mammography, ultrasound, and magnetic resonance imaging methods for early diagnosis of breast cancer. This technique plays an important role in early detection of breast cancer to women of all ages, including pregnant or nursing women, with different sizes of breast, irrespective of either fatty or dense breast. This proposed complementary technique makes use of infrared emission emanating from the breast. Emanating radiations from the surface of the breast under test are detected with an infrared camera to map the thermal gradients over it, in order to reveal hidden tumors inside it. One of the reliable active infrared thermographic technique, linear frequency modulated thermal wave imaging is adopted to detect tumors present inside the breast. Further, phase and amplitude images are constructed using frequency and time-domain data analysis schemes. Obtained results show the potential of the proposed technique for early diagnosis of breast cancer in fatty as well as dense breasts.

“…In general IRT can be implemented either in active or in passive approach [10]. In active mode, an external thermal stimulus (heating or cooling) is needed to produce significant thermal contrasts for the detection of subsurface variations and abnormalities located deep inside [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. However, in passive approach mapping of the thermal profile is carried out in the absence of any external stimulus [10].…”

“…Unlike, conventional pulse based (PT and PPT) or modulated (LT) thermographic techniques, the proposed scheme makes use of probing thermal waves into the test specimen within a desired band of frequencies of equal magnitude. This improves test resolution and sensitivity for identifying the sub-surface abnormalities in a single experimentation cycle with the use of medium peak power heat sources [15][16][17][18][19][20][21][22][23][24]. Active infrared thermographic techniques are equally applicable to medical imaging implementations for testing and evaluation of biomaterials.…”

Osteoporosis has been characterized as a skeletal disorder of reduced bone strength that leads to an increased risk of fracture. As the age of the person grows, early diagnosis of the disease is necessary to maintain good bone strength and to avoid unbearable fractures. While the disease cannot be reversed, it can be effectively managed by detecting bone density variations. Recently introduced non-stationary thermal wave imaging techniques have gained wide acceptance in the thermal non-destructive testing research community due to their merits over the conventional methods. This paper attempts to test the capabilities of one of the widely used non-stationary thermal imaging techniques to characterize the severity of osteoporosis in the modeled human bone. A 3D finite element analysis has been carried out to model a multilayered bone having different density variations, with tissue, skin and muscle over layers. Obtained results from frequency domain analysis scheme has been studied in order to detect the density variations with improved test sensitivity.
