AB  - Intravascular photoacoustic (IVPA) imaging can visualize the coronary 
      atherosclerotic plaque composition on the basis of the optical absorption 
      contrast. Most of the photoacoustic (PA) energy of human coronary plaque lipids 
      was found to lie in the frequency band between 2 and 15 MHz requiring a very 
      broadband transducer, especially if a combination with intravascular ultrasound 
      is desired. We have developed a broadband polyvinylidene difluoride (PVDF) 
      transducer (0.6 x 0.6 mm, 52 mum thick) with integrated electronics to match the 
      low capacitance of such a small polyvinylidene difluoride element (<5 pF/mm(2)) 
      with the high capacitive load of the long cable ( approximately 100 pF/m). The new readout 
      circuit provides an output voltage with a sensitivity of about 3.8 muV/Pa at 2.25 
      MHz. Its response is flat within 10 dB in the range 2 to 15 MHz. The root mean 
      square (rms) output noise level is 259 muV over the entire bandwidth (1-20 MHz), 
      resulting in a minimum detectable pressure of 30 Pa at 2.25 MHz.
