The 3D image quality of the system was demonstrated on a phantom consisting of a looped metal wire (wire diameter: 590 μm, loop diameter: 1.5 mm) placed at a distance of approximately 1.8 mm or 3.3 mm from the fibre bundle. The same four ultrasound transmission patterns (containing either 573 or 576 source locations) as used for the spatial resolution measurements were applied, as well as the same optical excitation and acoustical detection parameters. A time gain exponent α = 1.4 was used during image reconstruction. Finally, a volumetric image was acquired (using 10-fold averaging) of the inner wall of ex vivo porcine left ventricular heart tissue submerged in water.
