Cylindrical-view photoacoustic tomography using fibre-optic plano-concave microresonator sensors
The fibre-optic planoconcave optical microresonator is a new type of highly sensitive broadband optical ultrasound sensor with a near omnidirectional response. We investigate the applicability of this type of sensor to widefield photoacoustic tomography by using it within a cylindrical scanning system and compare the images acquired in phantoms and ex vivo tissues with those obtained with PVDF and PZT receivers and numerical k-wave simulations. This preliminary investigation is expected to inform the design of a preclinical full-view photoacoustic tomography system using fibre-optic plano-concave microresonator sensors.
