Simulation of the Beating Heart Based on Physically Modeling a Deformable Balloon
The motion of the beating heart is complex and creates artifacts in SPECT and x-ray CT images. Phantoms such as the Jaszczak Dynamic Cardiac Phantom are used to simulate cardiac motion for evaluation of acquisition and data processing protocols used for cardiac imaging. Two concentric elastic membranes filled with water are connected to tubing and pump apparatus for creating fluid flow in and o...
متن کاملReal-time Control of Angioplasty Balloon Inflation for Beating Heart Model
We report on real-time control of balloon inflation inside porcine arteries. In a first step, experiments were done in a coronary artery of an excised heart. In a second step, experiments were done in a beating heart setup providing conditions very close to in vivo conditions without the complications. A programmable syringe pump was used to inflate a compliant balloon in arteries, while intrav...
متن کاملBeating the Standard Model *
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersy...
متن کاملBeating the jetting regime
We study numerically the dynamics of jets and drops in a microcapillary coflow device. The co-flow stream encounters different flow regimes, including dripping, jetting. Using a level-set/finite element axysimmetric numerical simulation, we study the dynamics of breakup of a jet subject to flow rate perturbations. A scaling law for the width of the unperturbed jet is presented and compared to e...
متن کاملBeating the Pink
Introduction: Kaposi sarcoma (KS) is an HIV associated skin lesion. Kaposi sarcoma is rare in HIV negative patients and is associated with HHV-8 infection. Clinically it presents as a pink nodular mass, single or multiple which can mimic pyogenic granuloma and bacillary angiomatosis. The etiology associated with HHV-8. Treatment options modalities can vary between from electrocuatery to surgica...
