Light And Sound Gauge The Temperature Of Deep Tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient’s tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures of specific tissues deep inside the body.

Biomedical engineers at Duke University have demonstrated how photoacoustic imaging can take the temperature of deep tissue more quickly and accurately than current techniques. This discovery is expected to play an important role in advancing thermal-based therapies to treat cancer. The research appears February 12 in the journal Optica.

Tracking the temperature of internal tissues is essential for many biomedical studies and thermal therapies of cancers, often affecting a treatment’s efficiency or side effects.
