The second one is hyperspectral imaging, which shines light at full spectrum at the finger. Then it detects which wavelengths are absorbed, correlating that to known absorption spectra of inflammation.
‘The device uses two methods: hyperspectral imaging and optoacoustic imaging. The combined imaging modalities provide an bodily structure of the finger overlaid with any suspected sites of inflammation.’
Optoacoustic imaging is a cousin of ultrasound and the system naturally generates a 3D ultrasound scan of the finger. The combined imaging modalities provide an bodily structure of the finger overlaid with any suspected sites of inflammation.
Arthritis is a form of joint disorder that involves inflammation of one or more joints. There are over 100 different forms of arthritis. The most common form of arthritis is osteoarthritis, a result of trauma to the joint, infection of the joint, or age.
