Neural disorders ranging from brain cancer to Parkinsons
to epilepsy would greatly benefit from new diagnostic tools that noninvasively
detect biomarkers linked to abnormal tissue.
Photoacoustic imaging is emerging as a viable complement to the most popular
modalities. With real-time 3-D capability, contrast based on optical absorption,
and sub-mm spatial resolution, photoacoustic imaging offers attractive
attributes for imaging biological tissue. When a near-infrared (NIR) laser
source is used, it has an added benefit of excellent penetration into biological
tissue of several centimeters.
