Case studies have suggested the efficacy of catheter-free, electrophysiology-guided noninvasive cardiac radioablation for ventricular tachycardia (VT) using stereotactic body radiation therapy, although prospective data are lacking.We conducted a phase I/II trial in adults with treatment-refractory episodes VT or cardiomyopathy related to premature contractions (PVCs). Arrhythmogenic scar regions were targeted by combining anatomic and electric imaging standard therapy workflow followed...
Abstract Cardiac radiotherapy (RT) may be effective in treating heart failure (HF) patients with refractory ventricular tachycardia (VT). The previously proposed mechanism of radiation-induced fibrosis does not explain the rapidity and magnitude which VT reduction occurs clinically. Here, we demonstrate hearts from RT that radiation achieve transmural within timeframe reduction. Electrophysiologic assessment irradiated murine reveals a persistent supraphysiologic electrical phenotype,...
Effective dissemination is crucial if innovation and development in teaching learning higher education are to lead sustainable changes practice. In 2003, King used an agricultural metaphor challenge innovators understand the purposes behind their aims. Similar way that seed can be spread, one could choose widely scatter information, hope it grows wherever lands; actively direct scattering; or nurture propagate future adoption ongoing manner. A recent investigation into strategies Australian...
Supernova (SN) 1987A focused attention on the critical role of hydrodynamic instabilities in evolution supernovae. To test modeling these instabilities, we are developing laboratory experiments mixing under conditions relevant to Initial results were reported J. Kane et al. [Astrophys. 478, L75 (1997) and B. A. Remington al., Phys. Plasmas 4, 1994 (1997)]. The Nova laser is used generate a 10–15 Mbar shock at interface two-layer planar target, which triggers perturbation growth due...
Recent shortages of molybdenum-99 ((99)Mo) have led to an examination alternate production methods that could contribute a more robust supply. An electron accelerator and the photoneutron reaction were used produce (99)Mo from which technetium-99m ((99m)Tc) is extracted. SPECT images rat anatomy obtained using accelerator-produced (99m)Tc with those commercial generator compared. Disks (100)Mo irradiated x-rays produced by 35 MeV beam generate about 1110 MBq (30 mCi) per disk. After target...
Main text Since 1976, 23 laboratories have submitted 45 samples of 137 Cs to the International Reference System (SIR) for activity comparison at Bureau des Poids et Mesures (BIPM), with identifier BIPM.RI(II)-K1.Cs-137. The NRC (Canada) and TENMAK-NÜKEN (Türkiye) participated in key reference value (KCRV) has been updated. degrees equivalence between each equivalent measured SIR or linked from COOMET.RI(II)-K2.Cs-137 updated KCRV calculated results are given form a table. A graphical...
Purpose: Real-time acquisition of three-dimensional surface tracking has potential as an external surrogate for respiratory correlated CT imaging and radiation therapy. This study assesses the GateCT system (VisionRT, UK) by comparing real patient phantom output to current systems. Method Materials: Absolute accuracy was tested using a 4D motion platform (Washington University, St. Louis) programmed with real-patient trajectories. A cylindrical object attached arm surface. The optical RPM...
Purpose: The changes in the head design of new Varian TrueBeam compared to C-series linear accelerators, required modification electron scattering foils and their placement beam line. As a result, characteristics cannot be matched existing accelerator models (C-series). Extensive measurements were needed for determining comparison commissioning purposes. We present detailed analysis various dosimetric parameters measured Truebeam linacs. Methods: A Wellhoffer scanning system was used measure...
