SF is the scatter fraction, P is the prompt counts, D is the delayed counts, k is the random scaling factor, a is the axial cross-sectional area of the subject's torso and A is the axial cross-sectional area of the PET field of view.
c Radial and d axial cross-sectional images of X-ray CT of a cylindrical sample (D = 2 mm, L = 6 mm), the axis of which is perpendicular to the thin section.
The minimum axis of inertia generally corresponded very closely to the direction of the z-scan axis, meaning that CT slices were good representations of axial cross-sectional geometry (Figure 4).
The graft area was traced as a region of interest (ROI) freehand on the axial cross-sectional image.
It is generally approximately 7 mm in axial cross-sectional diameter and 15 30 mm long; it has been suggested that diameter larger than 10 mm correlates with the presence of an underlying malignancy.
The images consisted of axial cross-sectional and sagittal T2-weighted fast spin-echo, sagittal T1-weighted non-fat-suppressed, T1-weighted fat-suppressed DCE before and after contrast material administration, and DW sequences prior to gadolinium-based contrast material injection in axial orientation.
Differences in serial measurements over 3 months in patients with stable COPD were also small and comparable to those found with CT-based measures of muscle or adipose cross-sectional area as confirmed by axial cadaver sections [ 50, 51].
In this paper, the cross-sectional axial behaviour of concrete-filled elliptical hollow sections is investigated.
Based on the test results, effects of cross-sectional shape, axial load level and cross-sectional area of the inner CFST on the failure mode and the torque-rotation angle relation are investigated.
The cross-sectional axial velocity u= u(r) profiles at the downstream stations of X/D= 75,X/D="375,X/D="680 together with pressure losses ΔP are referred to determine the influence of utilized designs.
Axial, sagittal, cross-sectional images were reconstructed for all skulls, and 3D reconstructions were used as necessary (Fig. 3).
