Planned enrollment was 120 adults (≥ 18 years) having Karnofsky performance scores > 80% with recently diagnosed, pathologically confirmed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx, or related site, planned to receive a conventional course of external beam irradiation (single daily fractions of 2.0‐2.2 Gy) with a cumulative dose of between 50 Gy and 72 Gy.
In the system (B), the specimen is placed on a stand that rotates within its own axis in the course of the beam.
We have studied the energy shift introduced by surface charging during the course of ion beam analysis of an insulating material (a Kapton thin film) using Rutherford Backscattering Spectrometry (RBS).
To measure the interfraction and intrafraction motion of the prostate during the course of external beam radiotherapy using a video electronic portal imaging device and three-dimensional analysis.
After surgical resection of their tumour, patients had a course of external beam radiation therapy (standard dose, 40 Gy to the tumour with 3-cm margins, 20 Gy boost to the whole brain).
In the course of focused ion beam (FIB) preparation and electron microscopic (EM) study, the olivine particle RB-QD04-0042 turned out to contain inclusions of diopside, troilite, and tetrataenite.
Purpose: To describe the design and commissioning of a system for the treatment of classes of tumors that require highly accurate target localization during a course of fractionated external-beam therapy.
They are not there in person, of course, but beam from advertisements for Visa, "the only card accepted at the Beijing 2008 Olympic games".The credit-card company is one of the Olympics' 12 leading sponsors, which between them have paid $866m for a four-year association covering the Turin winter games in 2006 as well as the games in Beijing due to start next week.
The time course of locomotor activity (number of beam breaks per 5 min interval) over the whole 120 min testing session and total locomotor activity (total beam breaks from the time of amphetamine administration to the end of the study) are presented.
They're doing it for big bucks and on TV, of course, but beaming this sort of mega-reality into the homes of harassed housewives pigeonholes both them and their audience, reinforcing timeworn domestic patterns.
In the second type of CT scanner, the object is rotated within the course of the X-ray beam and the set-up allows the free positioning of the sample between the detector and the source, allowing the adjustment of the magnification level.
