AB  - A four dimensional data set of the cardiac cycle of a zebrafish embryo was 
      acquired using postacquisition synchronization of real time photoacoustic 
      b-scans. Utilizing an off-axis photoacoustic microscopy (OA-PAM) setup, we have 
      expanded upon our previous work with OA-PAM to develop a system that can sustain 
      100 kHz line rates while demodulating the bipolar photoacoustic signal in 
      real-time. Real-time processing was accomplished by quadrature demodulation on a 
      Field Programmable Gate Array (FPGA) in line with the signal digitizer. Simulated 
      data acquisition verified the system is capable of real-time processing up to a 
      line rate of 1 MHz. Galvanometer-scanning of the excitation laser inside the 
      focus of the ultrasonic transducer enables real data acquisition of a 200 by 200 
      by 200 pixel, volumetric data set across a 2 millimeter field of view at a rate 
      of 2.5 Hz.
