Patient-Specific Aortic Phantom With Tunable Compliance

Development of a patient-specific phantom model

Fully-automatic, patient-specific 3D aortic arch modeling for patient treatment with aortic arch anomalies

Timing and type of aortic wall abnormalities (AWC) repair are still being debated. Automatically patient-specific 3D aortic arch geometrical model estimation from MRI images can provide a better knowledge of the geometry of the aortic arch anomaly and can be useful to evaluate preoperatively the best treatment. Therefore, we have developed a software to automatically compute a patient-specific ...

Correlation of phantom‐based and log file patient‐specific QA with complexity scores for VMAT

The motivation for this study was to reduce physics workload relating to patient- specific quality assurance (QA). VMAT plan delivery accuracy was determined from analysis of pre- and on-treatment trajectory log files and phantom-based ionization chamber array measurements. The correlation in this combination of measurements for patient-specific QA was investigated. The relationship between del...

Simulated Pulse Wave Imaging for Local Stiffness Estimation in Patient–specific Aortas with Phantom Validation

Background: The aortic stiffness has widely been reported as an independent indicator of all–cause mortality and cardiovascular diseases. Traditional methods for measuring arterial stiffness in vivo involve either invasive procedures or provide a global average estimate. An attractive alternative for noninvasive estimation of local arterial stiffness is based on pulse wave imaging (PWI), a meth...

Patient-specific quality assurance of RapidArc treatments: Portal prediction dosimetry compared with phantom studies

Purpose: To validate a locally fabricated phantom of Imatrixx-2D Array by comparing its results with ArcCheck phantom and comparing portal dosimetry measurements with the two phantom studies. Materials and Methods: Electronic Portal Imaging Devices and Epiqa software were used for portal dosimetry. An Imatrixx-2D array with a locally fabricated phantom and ArcCheck cylindrical phantom were used...
