* A represents the largest diameter of the haematoma on axial CT cuts in centimetres, B the diameter of haematoma perpendicular to A on the same cut and C the number of CT slices in which haematoma is visible multiplied by the slice thickness
Computed tomography scan of the cranial coelom of the red-tailed hawk described in Figure 1, scanned transversely at 3.0-mm slice thickness
, demonstrating the caudal third of the sternum.
(1) All certified SPECT/CT systems used in the Phase 3 study must have a CT that provides an AC reconstruction slice thickness
of 5 mm or better.
T2WI images were scanned using a fast spin-echo sequence by multiple slices (15 slices; 1.8 mm slice thickness
and 1 mm interslice distance).
The interslice distance is chosen to be at least the slice thickness
to avoid cross talk between slices.
Tube current of 110 mAs, tube voltage of 120 kVp, attenuation-based on-line modulation of tube current (CARE dose) of 4 D, collimator width of 32x0.6 mm, screw pitch of 1.0, slice thickness
and spacing of 8 mm, and X-ray tube rotation time of 0.5s.

However there are still limitations such as the precision of details, which is dependent on technical limits (pixel size, slice thickness
) and the artifacts of CT scanning, the representation of bone structures without contact with surrounding bone structures, and the cost of stereolithographic models.
In reconstruction of CT data slice thickness
, slice increment and field of view parameters play's major role.
To calculate fat pad volumes, measured areas on individual slices were multiplied by the sum of slice thickness
and interslice gap and all volumes were added together for a total volume.
Conventional anatomical imaging sequences included axial T2-weighted fast spin echo (repetition time [TR]/repetition time [TE], 3500 ms/112 ms; slice thickness
, 5 mm; gap, 1 mm; field of view [FOV], 320 x 320 mm; and matrix, 320 x 256), coronal T2-weighted fast spin echo (TR/TE, 3400 ms/100 ms; slice thickness
, 5 mm; gap, 1 mm; FOV, 300 x 300 mm; and matrix, 320 x 224), sagittal T2-weighted fast spin echo (TR/TE, 3600 ms/100 ms; slice thickness
, 4 mm; gap, 1 mm; FOV, 280 x 280 mm; and matrix, 320 x 224), and axial T1-weighted spin echo (TR/TE, 660 ms/7 ms; slice thickness
, 5 mm; gap, 1 mm; FOV, 320 x 320 mm; and matrix, 352 x 192).
Clinical QCT scan resolution is controlled by two independent settings, that is, in-plane resolution and slice thickness
