However, the restricted availability of validated imaging parameters and low end-user awareness could limit the use of optical imaging technologies in research-specific applications. Moreover, the scope for alternative techniques usage and their strong presence (involving digital radiography, nuclear imaging techniques, and hybrid imaging) is likely to deter manufacturers from investing substantially in the development of novel optical imaging methods.
"From a technical standpoint, the key challenge is to address issues related to frozen sections arising from tissue processing steps," said Mr Prasanna Kannan. "This often results in freezing artifacts, which causes physical destruction of the structural integrity of tissues."
Despite such challenges, multi-modality imaging using optical imaging principles is helping drive the development of novel therapeutics and changing the course of patient management in debilitating disease care.
