Automated detection of cardiac phase from intracoronary ultrasound image sequences.
Intracoronary ultrasound (ICUS) is a widely used interventional imaging modality in clinical diagnosis and treatment of cardiac vessel diseases. Due to cyclic cardiac motion and pulsatile blood flow within the lumen, there exist changes of coronary arterial dimensions and relative motion between the imaging catheter and the lumen during continuous pullback of the catheter. The action subsequent...
متن کاملMechanism of lumen enlargement during intracoronary stent implantation: an intravascular ultrasound study.
BACKGROUND Intravascular ultrasound analysis has assessed mechanisms of lumen enlargement after nonstent interventions, but not after stenting. METHODS AND RESULTS Preintervention and postintervention intravascular ultrasound was used to study 25 de novo native coronary lesions treated with single MultiLink stents without preatheroablation. External elastic membrane, lumen, and plaque and med...
متن کاملAutomatic Key Frames Detection in Intravascular Ultrasound Sequences
We present a method for the automatic detection of key frames in Intravascular Ultrasound (IVUS) sequences. The key frames are markers delimiting morphological changes along the vessel. The aim of defining key frames is two-fold: (1) they allow to summarize the content of the pullback into few representative frames; (2) they represent the basis for the automatic detection of clinical events in ...
متن کاملIntracoronary ultrasound observations during stent implantation.
T he Palmaz-Schatz stent has been used successfully to improve primary angioplasty results, to treat large coronary dissections, or to prevent impending closure of the lumen.-1-5 The determination of successful stent implantation is based on the angiographic appearance. However, angiographic projection imaging may not reveal the three-dimensional geometry that is necessary to appreciate full ex...
متن کاملOverview of Intracoronary Brachytherapy for in-Stent Restenosis of a Drug-Eluting Stent
Percutaneous coronary intervention with stenting is considered recently as the most common procedure for the treatment of symptomatic coronary. The article reviewed 41 studies published during 1997-2019 on intracoronary brachytherapy for in-stent restenosis of a drug-eluting stent. Intracoronary radiation therapy was finally confirmed in the setting of in-stent restenosis using as adjunctive th...
