Four-dimensional computed tomography image-based motion management provides an opportunity to individualize target motion margins and reduce the risk of a geographic target miss.
In the era of three-dimensional (3D) conformal radiotherapy, a tumor is usually imaged at a random time point by a free-breathing CT and encompassed by a generalized empirical respiratory-motion margin.
To account for setup uncertainty and respiratory motion, a margin of 8 mm isotropically was added to the CTV to form the PTV.
However, the expansion of static PET/CT-defined volumes with population-based motion uncertainty margins reduces the difference with patient-specific MIP PET/CT-defined volumes.
They transported him, in one motion, from the margin of the league to the forefront of it.
MPs backed the Government's motion by a margin of 397 to 223 - a higher-than-expected majority of 174.
(3) Glacial carving and corresponding development of the large fjord system has a significant influence on vertical motion of passive margins of central (east and west) Greenland and can explain up to 1.2 km uplift.
The House of Representatives approved the motion by the convincing margin of 422 votes to none and the Senate "concurred".Sudanese officials were so shocked that they switched off their mobile telephones en masse, to give themselves time to craft a response.
Investigated quality components comprise scalar quality, grey level spread, iris size, pupil-iris ratio, usable iris, iris-sclera contrast, iris-pupil contrast, iris shape, pupil shape, margin, sharpness, motion blur, signal-to-noise ratio, and gaze angle [16].
Right-lateral motion along the southern margin of the BSRZ, also known as the Oita-Kumamoto Tectonic Line (Yabe 1925), is thought to have been active since 0.5 Ma following the onset of dextral motion of the Median Tectonic Line in Shikoku Island (Fig. 1a) since 2 Ma (Tsukuda 1990), involving several caldera-forming eruptions.
Thinning of the upper crust could use a detachment suggested from an imaged dipping intracrustal reflector that would allow upper crustal material to be dragged from beneath it and above the lower crust, accounting for the extensional component but also southwest motion of the southern margin of the NMT.
