Photoacoustic Microscope

TOKYO, Nov. 18, 2016 — The Hadatomo photoacoustic microscope from Advantest Corp. utilizes a proprietary hybrid imaging technology to enable noninvasive imaging of blood vessels in the dermis to a depth of 3 mm.
Photoacoustic imaging combines the propagation characteristics of ultrasound and the absorption characteristics of light into a new hybrid imaging method. By using ultrasound technology, it can obtain accurate information to a depth of several millimeters. Hemoglobin selectively absorbs the energy of light and returns ultrasonic waves to the surface of the skin, where they can be captured by sensors. The information obtained can be displayed numerically and as a high-contrast map of blood vessels in the dermis.
The microscope features a wavelength of 532 nm, with a measurement time of 10 to 80 s, depending on case specifics.
