Radiation oncology is a medical discipline mainly involved in the treatment of cancer with ionizing radiation. It is based on full knowledge of individual patient cancer disease, delineation of the target volume including tumor that has to receive therapeutic radiation dose, delineation of normal tissues to be spared, treatment planning with dedicated calculation algorithms, radiation delivery ...
This paper introduces Accelerator Toolbox (AT) a collection of tools to model storage rings and beam transport lines in the MATLAB environment. The objective is to illustrate the flexibility and efficiency of the AT–MATLAB framework. The paper discusses three examples of problems that are analyzed frequently in connection with ring-based synchrotron light sources. 1 BACKGROUND AT is being devel...
Welcome to this special issue on accelerator virtualization in Concurrency and Computation: Practice Experience. Virtualization is a key technique developed for sharing the underlying physical resources of computer, such as processor or memory network. This enables effective use by improving their utilization reduces costs. A well-known example are virtual machines that have become prominent wi...
The neutron irradiation system for boron neutron capture therapy (BNCT) using compact accelerators installed at hospitals was mainly investigated for the usage of direct neutrons from near-threshold Li(p,n)Be, and moderated neutrons from 2.5 MeV Li(p,n)Be reactions and other reactions. This kind of system can supply the medical doctors and patients with convenience to carry out BNCT in hospital...
BACKGROUND The Mission: Lifeline STEMI Systems Accelerator program, implemented in 16 US metropolitan regions, resulted in more patients receiving timely reperfusion. We assessed whether implementing key care processes was associated with system performance improvement. METHODS AND RESULTS Hospitals (n=167 with 23 498 ST-segment-elevation myocardial infarction patients) were surveyed before (...
