Super-Sensitive PAM Ensures Image Quality with Low-Power Light Source

Posted by in categories: biotech/medical, futurism

A multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical resolution photoacoustic imaging.

By providing an exceptionally high level of sensitivity, SLD-PAM could help broaden the use of photoacoustic microscopy in biomedical applications. In the future, it could translate to clinical settings; for example, it could be used for ophthalmic exams where a low-power laser is preferred for the patient’s safety and comfort. Long-term monitoring of pharmacokinetics or blood flow also requires low-dose imaging to alleviate perturbation to tissue function.
