Background: Case studies have suggested the efficacy of catheter-free, electrophysiology-guided
noninvasive cardiac radioablation for ventricular tachycardia (VT) using stereotactic …

… for more than 3 s or (ii) the monitor chamber readings differ by more than 5% from their
nominal rate for more than three consecutive rolling 10 s windows. A new 10 s window is started …

The requirement of an independent verification of the monitor units (MU) or time calculated
to deliver the prescribed dose to a patient has been a mainstay of radiation oncology quality …

The present work systematically examines the self-dose and cross-dose contributions from
intracellularradioactiv ity within small micrometastases. Model calculations are performed to …

Purpose: Recent years have witnessed tremendous progress in image guide radiotherapy
technology and a growing interest in the possibilities for adapting treatment planning and …

… calculate cellular S-values for several radionuclides. … , S-values are given for radionuclides
in the 212Pb decay series, including 212Pb, 212Bi and 212Po. Both absorbed fractions and S…

PURPOSE: To evaluate the feasibility of using helical tomotherapy for locally advanced left-sided
breast cancer. METHODS AND MATERIALS: Treatment plans were generated for 10 …

… Errors in the S values when the source and target regions are the same was <5% for all 3
