To present an automated technique for two-field tangential breast intensity-modulated radiotherapy (IMRT) treatment planning.
For both left- and right-sided radiotherapy and with the use of either tangential fields or intensity-modulated radiation therapy (IMRT), most of the heart receives >1 Gy dose from scattered irradiation (Li et al, 2000).
Current methods for intensity-modulated radiotherapy (IMRT) in breast cancer use forward planning based on equivalent radiological path length to design intensity modulated tangential beams.
The inflowing swirl generated by two tangential inlets has the same intensity in all cases considered.
Increasing the fine particle outlet diameter decreases both the tangential velocity and the turbulent intensity, thereby increasing the cut size.
For a given FSD, the lower limit of Do can be determined from the flow stability characterized by lower turbulence intensity and larger tangential velocity.
With increasing extrusion intensity, the maximum tangential residual tensile stresses around the hole increases, while, the hole diameter and e/d showed no significant influence on the residual tangential stresses.
Incubation with peroxynitrite generators induced an increase of D-band, due to defects in sp-hybridized carbon systems, and a decrease of the intensity of the tangential G mode, leading to the increased intensity of the D/G ratio.
Vascular endothelial cells are submitted to various types of blood flow exerting tangential and perpendicular forces, the intensity of which plays an important role in endothelial cell homeostasis [ 5].
It was found that when the oscillation intensity is increased, the tangential motion of the flow increases faster than the increase in radial flow because the vortex sizes are bounded by the column diameter.
