Hyperspectral Imaging Technology Finds Application in Earth-Monitoring and Healthcare

 

Hyperspectral Imaging utilizes a high-frequency sound wave for producing high-frequency images of the patient's body. These images can be compared to conventional x-ray or computed radiography. A medical imaging specialist uses a variety of methods to capture a sample of the patient's body. One of these methods is called hyperspectral imaging. This process has two components, the primary component consists of a scanner that captures the reflected sound wave and an instrument called a thin probe that collects the waves.

One method used in the process of Hyperspectral Imaging is called the morphic domain technique. It uses a series of lasers and an instrument called a morphoscope. The different wavelengths of light that are reflected are collected on the flat monitor that is placed above the patient's abdomen. In this way, the reflected data cube of the patient is reconstructed by the computer. A computer program reconstructs the data cube with the help of the patient's bones and the distributed muscle fibers.

The second method used in the process of Hyperspectral Imaging involves the use of a broadband analyzer that converts the reflected data into electrical signals. These signals are then analyzed by a computer using mathematical algorithms. This technique is used to obtain information about the reflected electromagnetic spectrum. This kind of imaging provides excellent images of the organs like the heart and the brain without making use of high-frequency electromagnetic radiation like x-rays and gamma-rays. These kinds of techniques can also be used to determine the properties of the inner structure of the human body including bone and muscle structures.

Hyperspectral imaging finds application in earth monitoring. In December 2019, Headwall Photonics, Inc., a manufacturer of spectral imaging instruments, software, and solutions, announced that its High-Efficiency Hyperspec Sensor System was launched into space for a multi-year, earth-monitoring research mission aboard the International Space Station. The mission supports research being conducted by Japan Space Systems, a space exploration organization in Japan.
