Deposited using inking techniques (Figure 8(b)), the 50 individually addressable electron beams allow for arbitrarily defined, and controllable electron, and hence X-ray beam shapes, for application in radiotherapy.
The basic principle of the station is in the use of various geometrical combinations of polycapillary optics for X-ray beam shaping (focusing/collimation) at specially designed laboratory unit.
However, these are less accurate when compared to conventional RSA, and additional CT models are needed. de Bruin et al. 2008; Seehaus et al. 2012) Previous attempts to use MRI models instead of CT have failed, because MRI models interfere with the used X-ray shape-matching procedure which is based on Hounsfield units.(Moro-oka et al. 2007).
As the detectors are sensitive to neutron and gamma rays, pulse shape analysis is required for neutron/gamma discrimination.
The structural properties of the Pt Ru model electrodes, such as lattice constant, grain size and alloy composition, were investigated by X-ray line shape analysis and scanning electron microscopy (EDX).
Digital processing techniques are now being applied to the TNS to handle some of the more complex analogue functions, particularly neutron/γ-ray pulse-shape discrimination for the photo-scintillator column.
Ferrero described the amazing results that paleontologists were getting with fossilized eggs — the X-rays showed the shape and the density of the embryos inside.
In particular, we introduce an extension of ray-representation to shape interior modeling, and prove this parametrization covers the optimal interior regarding static and rotational stability criteria.
The pectoral fin disc of the bluespotted ribbontail ray is oval in shape, around four-fifths as wide as long, with a rounded to broadly angular snout.
The pectoral fin disc of the longtail butterfly ray has the lozenge shape characteristic of its family, measuring around twice as wide as long.
