Intensity-modulated radiation therapy
Current Problems in Cancer, 2004For the non radiotherapist, the recent developments of conformal radiotherapy and Intensity Modulated Radiotherapy (IMRT) may represent merely an increase in mystification from a baseline already shrouded in the obscure dark arts of physics. However, the principles of these developments are simple and as the technologies become available, there are ...

Intensity-Modulated Radiation Therapy
Radiation Research, 2002Intensity-modulated radiation therapy (IMRT) is an increasingly popular technical means of tightly focusing the radiation dose around a cancer. As with stereotactic radiotherapy, IMRT uses multiple fields and angles to converge on the target. The potential for total dose escalation and for escalation of daily fraction size to the gross cancer is ...

Intensity Modulation of Olfactory Acuity.
Behavioral Neuroscience, 2003Acuity is fundamental to sensory systems, establishing the foundation for detectable differences in stimulus quality and consequently shaping animals' sensory capacities. In the olfactory system, which samples intrinsically high-dimensional chemical information, acuity for odor quality is measurable by means of ad hoc dimensions based on behaviorally ...

Modulation of turbulence intensity by heavy finite-size particles in upward channel flow
Journal of Fluid Mechanics, 2021It has been recognized that, generally, large particles enhance the turbulence intensity, while small particles attenuate the turbulence intensity.

Compensators for intensity-modulated beams
Medical Dosimetry, 2002This study describes the importance of attenuator scatter in the construction of compensators. The attenuator used in this study was Lipowitz metal, commonly referred to as cerrobend. Linear attenuation coefficients of cerrobend were measured in air for different thickness of cerrobend sheets and different field sizes for a 6-MV photon beam.

Intensity-modulated moiré topography
Applied Optics, 1999Moiré topography has the advantage of requiring only a single image to obtain a three-dimensional measurement, but it cannot discern the fringe order. Because there is an ambiguity problem when calculating the depth range by use of fringe intensity or phase unwrapping, it is impossible to obtain an absolute phase and an absolute depth range.
