N2 - Accurate localisation of medical devices is of crucial importance for a wide range of ultrasound-guided interventions. In this study, we investigated visualisation of medical devices by photoacoustic excitation of optically absorbing coatings. Photoacoustic excitation light was provided through optical fibres positioned within a cardiac needle and a steerable-tip catheter. Using a swine heart model, photoacoustic and B-mode ultrasound images were received with a clinical ultrasound scanner in conjunction with a transoesophageal imaging probe. In the photoacoustic images, prominent signals were obtained from the coatings. This study demonstrated that photoacoustic imaging could play a useful role with medical device imaging.
