Sentence examples for phantom method from inspiring English sources

However, Nakajima et al. have recently shown that standardization of H/M ratios by a heart chest calibration phantom method is feasible among different collimator types, allowing practical multicentre comparisons of H/M ratios [ 27].

Various studies demonstrated techniques to minimize these artifacts; Kuo et al. (2010) examined an in-phantom method using inversion recovery with ON-resonant suppression (IRON) to generate positive contrast in areas of high magnetic susceptibility artifact (Kuo et al. 2010).

The DXA device was calibrated daily and weekly by using appropriated phantoms methods.

In the current study, the traditional phantom node method is extended for crack propagation modeling of composite materials under fatigue loading.

The presented fatigue phantom node method is coded as an user-defined element in ABAQUS and its numerical implementation, including global data, element connectivity and, especially, a pre-cracking treatment, has been discussed in detail in consideration of limitations from the commercial FE software.

When the phantom replacement method was used, the calculated concentrations were strongly dependent on coil loading conditions.

We compared these results to parallel estimates of concentrations obtained using the more established phantom replacement method.

In contrast, the concentrations determined using the phantom replacement method are highly dependent on coil loading conditions.

When the surface coil was overloaded during the calibration session, the phantom replacement method consistently overestimated the metabolite concentrations by about 10%.

In contrast, the concentrations determined with the phantom replacement method were clearly erroneous when in vivo coil loading conditions were not properly replicated during the calibration session.
