Brilliance ct big bore oncology scanner

A CT scan of a female torso, acquired on a Brilliance CT Big Bore Oncology scanner (Philips, Hamburg, Germany) operating at 290 mA and 120 kV, was used to obtain the data for both morphology and density values as the basis for an anthropomorphic phantom representing part of the left upper arm (Figure 1). Based on density (CT numbers), the images were segmented in 3D Slicer (Alliance for Medical Image Computing (NA-MIC), Boston, MA, USA) into tissue classes corresponding to skin, cortical bone, bone marrow and soft tissue. The segmented tissues were exported as Standard Transformation Language (STL) files.

For the CT examination the horses were positioned in right lateral recumbency on a stationary examination table. CT was performed using a Brilliance™ CT – Big Bore Oncology Scanner (Philips Medical Systems, Best, The Netherlands).
The entire head of each horse was scanned with an axial scan-mode with 140 kV, 500 mAs, a slice thickness of 1.5 mm and an image matrix of 1024. Using multiplanar reconstruction, two transverse image sequences, one with a bone window (CTbw; WL: 300, WW: 2800), and one with a soft tissue window (CTstw; WL: 50, WW: 500) were generated. Both sequences were oriented perpendicular to the hard palate.
