Latest Patents

**Spectroscopic photoacoustic imaging.** This invention describes an imaging approach that estimates the extent of tissue necrosis during ablation therapy. Pulsed laser light directed at the treatment region generates acoustic signals, and variations in the photoacoustic spectrum help distinguish ablated tissue from untreated tissue. The system quantifies tissue contrast to estimate the degree of necrosis and produces images that can provide continuous or near-continuous feedback to guide treatment.

**Spectroscopic photoacoustic imaging probe.** This invention describes a probe that combines optical illumination sources with an ultrasonic receiver to define an imaging plane. Optical fibers deliver light to the target region, while an ultrasonic array detects the resulting photoacoustic signals. The probe can render images on a visual device and may be used alongside an ablation antenna or diagnostic probe to support imaging during a procedure.
