Hadatomo™ Photoacoustic Microscope
Quasi-Real Time Imaging
Imaging of a 4 mm square area takes just 20 seconds.
High-speed imaging reduces patient stress and improves diagnosis times.
Proprietary Image Reconstruction Algorithms
Advantest's proprietary image reconstruction algorithms eliminate the need for an optical lens or acoustic lens, providing sharp, clear images regardless of the depth of the target area.
Setup is easy, requiring no calculations of target area depth.
No contrast agent required
The Hadatomo's compact frame makes it easy to move around.
Its flexible arm enables analysis of hard-to-reach areas.

Principles of Photoacoustic Imaging
Existing ultrasound technology can noninvasively provide images of tissue structures by contrasting the relative hardness of constituent areas. However, it is inadequate to image areas within the dermis, where little hardness contrast exists.
Conversely, optical imaging tools such as microscopes cannot "see" even 1mm beneath the skin.
Photoacoustic imaging combines the propagation characteristics of ultrasound and the absorption characteristics of light into a next-generation hybrid imaging method that is used for R&D worldwide.
When pulses of light are irradiated into the target area, hemoglobin selectively absorbs their energy and returns ultrasonic waves to the surface of the skin, where they can be captured by sensors at the surface. Based on how long it takes for the waves to return, the depth of the target can be accurately measured and imaged.
