A.; Lobostein, K.; Villa-Uriol, Maria-Cruz; Zhang, Chong; Frangi Caregnato, Alejandro; Mercier, G.; Bonafé, A.; Sarry, L.; Jourdan, F. (Elsevier, 2011)
    Background and purpose: Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength ...

    Endovascular coiling is a well-established therapy for treating intracranial aneurysms. Nonetheless, postoperative hemodynamic changes induced by this therapy remain not fully understood. The purpose of this work is to ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    This paper presents a technique to estimate and model patient-specific pulsatility of cerebral aneurysms over one/ncardiac cycle, using 3D rotational X-ray angiography (3DRA) acquisitions. Aneurysm pulsation is modeled as ...
  • Zhang, Chong (Universitat Pompeu Fabra, 2011-07-28)
    Over the last decade, there has been a growing interest in assessing cerebral aneurysmal wall motion, because of its potential connections to the biomechanical conditions of the vessel wall, which could eventually aid the ...
