As a conclusion, several factors including problems related specifically to intravascular ultrasound as well as general limitations of the three-dimensional reconstruction can affect the quality of the IVUS analysis, in particular vessel three-dimensional reconstruction. Both lumen and plaque volumetric measurements showed short-term biological variablity during repeated pull-back of the same coronary segment [83]. The quality of the basic intravascu-lar ultrasound images is crucial; the image resolution is under continuous improvement by commercial IVUS device producers. Improving image quality, avoiding image artifacts, as well as assuring constant catheter motion will significantly contribute to a better understanding of and developing more robust image processing and computer vision techniques. At the same time, more clinical studies on IVUS are necessary to elucidate the important problems and real advantages of diagnosis and therapy IVUS images. On the other hand, although experts from image processing and computer vision have presented a lot of interesting and valuable work, there is still not enough transference of research studies into clinical practice. There are a lot of still open problems and questions in IVUS analysis and, in to our opinion, image devices technologists, physicians, and computer vision researchers should continue to work together to achieve really valuable computer-assisted tools for precise diagnosis and therapy by IVUS in an effort to further determine its clinical importance and its routine clinical use. Definitely, IVUS analysis is an interdisciplinary field of research as proved by several works published by such interdisciplinary teams.
