AB  - Frequency domain optical coherence tomography (FD-OCT) has become one of the 
      important clinical tools for intracoronary imaging to diagnose and monitor 
      coronary artery disease, which has been one of the leading causes of death. To 
      help more accurate diagnosis and monitoring of the disease, many researchers have 
      recently worked on visualization of various coronary microscopic features 
      including stent struts by constructing three-dimensional (3D) volumetric 
      rendering from series of cross-sectional intracoronary FD-OCT images. In this 
      paper, we present the first, to our knowledge, "push-of-a-button" graphics 
      processing unit (GPU)-accelerated framework for intracoronary OCT imaging. Our 
      framework visualizes 3D microstructures of the vessel wall with stent struts from 
      raw binary OCT data acquired by the system digitizer as one seamless process. The 
      framework reports the state-of-the-art performance; from raw OCT data, it takes 
      4.7 seconds to provide 3D visualization of a 5-cm-long coronary artery (of size 
      1600 samples x 1024 A-lines x 260 frames) with stent struts and detection of 
      malapposition automatically at the single push of a button.
