ActiveVessel is a new multimedia workstation which enables the visualization, acquisition and handling of both image modalities, on-and offline. It enables DICOM v3.0 decompression and browsing, video acquisition, reproduction and storage for IntraVascular UltraSound (IVUS) and angiograms with their corresponding ECG, automatic catheter segmentation in(More)
Lumen volume variations is of great interest by the physicians given it reduces the probability of infarction as it increases. In this paper we present a fast and efficient method to detect the lumen borders in longitudinal cuts of IVUS sequences using an AdaBoost classifier trained with several local features assuring their stability. We propose a(More)
The growing appreciation of the pathophysiological and prognostic importance of arterial morphology have led to the realization that angiograms are inherently limited in defining the distribution and extension of coronary wall disease. By IntraVascular UltraSound (IVUS) physicians have a picture of the composition of vessel in detail. However, observing an(More)
OBJECTIVES This study sought to evaluate late recoil of a novel bioabsorbable everolimus-eluting coronary stent (BVS), which is composed of a poly-L-lactic acid backbone, coated with a bioabsorbable polymer containing everolimus. BACKGROUND Little is known about the mechanical behavior of bioabsorbable polymer stents after deployment in diseased human(More)

Bioabsorbable drug-eluting coronary stents present a very promising improvement to the common metallic ones solving some of the most important problems of stent implantation: the late restenosis. These stents made of poly-L-lactic acid cause a very subtle acoustic shadow (compared to the metallic ones) making difficult the automatic detection and(More)
ActiveVessel is a new multimedia workstation that enables the visualization, acquisition, and handling of different medical image modalities on-and off-line for cardiology purposes. The workstation implements image decompression and browsing, video acquisition, reproduction, and storage for intravascular ultrasound (IVUS) and angiogram (X-ray) analysis. A(More)
We present ActiveVessel-a new multimedia medical workstation, which supports visualization of cardiological diseases and helps early and precise diagnosis and treatment. The workstation is developed with the close participation of medical staff of University Hospital Germans Trias i Pujo, Barcelona. ActiveVessel is an advanced tool for medical image(More)
