Bias and Variability In Image-Based Volumetric Yttrium-90 Dosimetry
… to the patient, which allow gross treatment delivery verification and limited outcome prediction.</p> <p>We have also characterized the accuracy and variability of volumetric 90Y dosimetry calculated from count-limited 90Y-PET/CT images. Knowledge of overall errors (systematic and random) in …

3D Scintillator Detector Quenching Characterization For Scanning Proton Beams
… beam scanning is becoming the standard treatment delivery technique for proton therapy centers. Scanned proton pencil beams provide a highly conformal dose distribution. The complex dose distribution poses challenges for quality assurance measurements leading to sophisticated detector setups and …

Comprehensive Calculation-Based Imrt Qa Using R&V Data, Treatment Records, and A Second Treatment Planning System
… system, and various aspects of the physical delivery.<strong> </strong></p> <p><strong>Methods: </strong>We recomputed the treatment plans in the patient geometry for 48 cases using data from the R&V, and from the delivery unit to calculate the “as-transferred” and “as-delivered” doses …
