AB  - Pilot studies of in vivo combined intravascular ultrasound (IVUS) and 
      intravascular photoacoustic (IVPA) imaging are reported. A recently introduced 
      prototype of an integrated IVUS/IVPA imaging catheter consisting of a 
      single-element ultrasound transducer and a light delivery system based on a 
      single optical fiber was adapted and used for in vivo imaging of a coronary stent 
      deployed in a rabbit's thoracic aorta in the presence of luminal blood. The 
      results suggest that in vivo IVUS/IVPA imaging is feasible using the integrated 
      IVUS/IVPA imaging catheter. The challenges of in vivo combined IVUS/IVPA imaging 
      are discussed, and further improvements on the design of the catheter and the 
      clinical imaging system are proposed.
