PACT creates in vivo 3D functional imaging of the brain
PACT creates in vivo 3D functional imaging of the brain 09 Jun 2021 Latest advance from Caltech group demonstrates photoacoustic tomography as route to brain imaging. Lihong Wang: novel photoacoustic applications Photoacoustic computed tomography (PACT) builds on the principles of photoacoustic imaging to create images of blood vessels and angiographic structures. The technique uses non-ionizing laser pulses to briefly heat up an absorbing target before allowing it to cool, causing an expansion that in turn creates an ultrasound signal. That signal can then be reconstructed in a manner anal...
