High-frequency acoustic imaging, incorporating both low-frequency hyperspectral imaging and high-frequency spectroscopic imaging, is an exciting new development in modern physics and applications in mineralogy, astronomy, archeology and health sciences, improving detection capabilities to identify, isolate and study biological or environmental samples. A variety of scientific disciplines utilize this technology, ranging from biomedical imaging, chemistry, environmental monitoring, energy, physics, astronomy, biochemistry, clinical genetics, anthropology, art history, applied research, pathology, pharmacology, physiology, psychiatry and statistics.

Hyperspectral is derived from the Greek words "hypnos" (concealed) and "sphragmos" (clear sight). In its most common application in mineralogy, it provides clear sight of minerals and rocks from a distance. With a relatively high sensitivity and ability to scan large areas, it has been a key tool for mineral exploration and for quality control in production plants. Low-frequency tools use radio frequency energy to create an image of mineral grains or nodules that lie below the surface. With high frequency, the instrument can also detect small quantities of dissolved organic compounds in water or oil. These specialized instruments are often mounted on remotely operated vehicles, which makes them much easier to work in inaccessible or hazardous situations.

Hyperspectral imaging also finds application in aromacology to determine the source of flower essences, as well as other organic compounds found in aqueous solutions. In surgery, this imaging technology has been used in joint replacement and arthroplasty. The application of fluorescent dye in the joint preparation can help visualize the anatomy beneath the bursa and synovial fluid, allowing the surgeon to better visualize the site of repair. This method of visualization has also been used in orthopedic surgery, particularly in shoulder replacement surgeries. Another application in the medical field is focused ultrasound. This application involves inserting a probe into the body cavity. A powerful ultrasound beam is then directed at the body part being investigated. By using this probe, radiologists can determine the heart conditions in patients and evaluate various diseases and abnormalities. It has also been applied to study the brain, especially in its response to neurostimulation.

Hyperspectral imaging is used in diagnosis and treatment of various diseases. For example, cardiology utilizes the approach to make detailed comparisons between patients who have mild heart disease and those who do not. The differences are shown on a CT scan to help make a more accurate diagnosis. Similarly, gynecologists use this type of technology in order to detect problems in early pregnancy.

One of the many applications of hyperspectral imaging in the field of health sciences focuses on breast cancer detection. Breast cancer is one of the leading causes of death in women. In some cases, such as with breast cancer detection, doctors use a technique called mammography. The probe imbedded in the breast produces a shadow image of the breast, which can then be seen by the doctor. This is an extremely effective breast cancer detection method which has a high accuracy rate.

Hyperspectral imaging is applied in a wide variety of prevention research. For example, it has been applied to studying the effect of low intensity aerobic exercise on the development of cardiovascular disease. It has also been studied to determine whether or not there is a protective effect by reducing the risk of sudden death due to heart attacks in those who have a history of heart disease. This application has been very successful in reducing the number of cardiac deaths in these studies.
