Percutaneous radiofrequency ablation (RFA) is used to destroy small liver tumors by locally inducing heat. However, there is a high tumor recurrence rate due to insufficient real-time image guidance during the procedure. We studied multi-wavelength photoacoustic imaging for identifying ablated tissue by taking the ratio of the photoacoustic signals at two wavelengths. To realize this, we first simulated the optical penetration in the liver and its influence on the optimal wavelength pair. Finally, the photoacoustic signals of treated and untreated bovine liver tissue were measured between 680 nm to 1100 nm to find candidate wavelength pairs for successful ratio imaging.
