Researchers demonstrate an alternative way to produce highly detailed images of the brain

Researchers demonstrate an alternative way to produce highly detailed images of the brain The gold standard in functional brain imaging for over two decades, functional magnetic resonance imaging (fMRI) has transformed the landscape of research and clinical care. Yet, because of its cost and functional limitations, scientists have continued to look for new ways to see into the human brain. Researchers from the Keck School of Medicine of USC and the California Institute of Technology (Caltech), with the help of patients recovering from traumatic brain injury, have now demonstrated an alternative way to produce highly detailed images of the human brain. Their work, published in

Breakthrough in brain imaging may offer future alternative to functional MRI

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 analogous to functional MRI, generating an image showing the distribution of optical absorption inside the target.
