Summary:

  • Laser ablation procedures serve various applications ranging from fetal-based maladies to cancer therapies.

  • Imaging artifacts in US imaging, high costs, limited intra-operative guidance in magnetic resonance, and motion artifacts in X-ray imaging limit the catheter position detectability, hindering the safety of image-guided interventions.

  • Lack of real-time temperature monitoring induces additional complications, limiting the effectiveness of therapeutic doses delivered to the patient.

  • PA imaging complements a hybrid touch to US imaging, revealing optical properties of the target tissue. Together with US imaging visualizing the anatomical structures, PA imaging enhances image-guidance techniques by providing the real-time location of the catheter tip and tissue thermometry
