<p><strong>Photoacoustic tomography is a promising technique for noninvasive medical imaging of biological tissues. In a recent review, researchers focus on the optical component of quantitative photoacoustic tomography, where the distributions of the optical parameters are estimated from the initial pressure. The review discusses how light propagation in a tissue is modelled, the numerical solution methodologies of the image reconstruction, and the challenges that must be addressed for real-world applications. </strong></p>

Decisions on cancer treatment could become better tailored to individual patients with the adoption of a new imaging method being developed by University of Michigan researchers that maps the chemical makeup of a patient’s tumor.

The need to deliver the intended, optimal radiation dose to a tumor while sparing the healthy tissue surrounding the cancer is critical to cancer trea

A technique that tracks radiation in real time promises safer, more effective cancer therapy with less collateral damage, researchers say.
