Segmentation and Grid Generation for Numerical Simulations of VAD Connections with Patientspecific Data

Alfio Quarteroni, Simone Deparis, Elena Faggiano, Jean Bonnemain, Ludwig Von Segesser

Objectives: We are interested in the numerical simulation of the anastomotic region comprised between outflow canula of LVAD and the aorta. Segmentation, geometry reconstruction and grid generation from patient specific data remain an issue because of the ...

Increase of [F-18]FLT Tumor Uptake In Vivo Mediated by FdUrd: Toward Improving Cell Proliferation Positron Emission Tomography

Rolf Gruetter, Bernard Lanz, Carole Poitry-Yamate, David Viertl, Hans-Anton Lehr

3'-deoxy-3'-[F-18]fluorothymidine ([F-18]FLT), a cell proliferation positron emission tomography (PET) tracer, has been shown in numerous tumors to be more specific than 2-deoxy-2-[F-18]fluoro-d-glucose ([F-18]FDG) but less sensitive. We studied the capaci ...

A Handheld Probe for beta(+)-Emitting Radiotracer Detection in Surgery, Biopsy and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Christian Mester

We present a new, handheld probe for radiotracer detection in vivo and inside operating theatres, where PET scanners cannot be used for radioguided surgery. The device is based on scintillation detectors optically coupled to Silicon Photomultipliers (SiPMs ...

Spatiotemporal motion estimation for respiratory-correlated imaging of the lungs

Jan Kybic

Purpose: Four-dimensional computed tomography (4D CT) can provide patient-specific motion information for radiotherapy planning and delivery. Motion estimation in 4D CT is challenging due to the reduced image quality and the presence of artifacts. We aim t ...

Monitoring tumor response to radiation therapy with longitudinal and multimodal molecular imaging

Jessica Perez

Purpose: Metabolic changes induced by radiation therapy (RT) provide a biological measure of tumor response to treatment beyond anatomic changes. In this preclinical study we investigated these changes through longitudinal monitoring of tumor response to v ...
