Experimental Setup for Blood Flow Velocity Measurements Using AR-PAF (IMAGE)
Caption
Experimental setup for blood flow velocity measurements using AR-PAF. A polyethylene tube of 580 μm inner diameter serves as a vessel phantom. It is illuminated with successive laser pulses to generate PA signals. Blood flow through the tube is controlled using a syringe pump. The PA signals are detected with a 64 element ultrasound transducer array (center frequency=15??MHz). The array is positioned such that a cross section of the tube is imaged, and the orientation at an angle θ to the tube enables motion of the cells to be observed as a displacement in the axial direction of the transducer. The phantom and the transducer were held in place using custom-made holders.
