Scan and Reconstruction
Straton-Tube
The SOMATOM Sensation Cardiac CT-system is now
equipped with the Straton-tube. This newly developed
X-ray tube offers significantly reduced cooling times
for shorter interscan delays and increased power
reserves. The full X-ray power of 60 kW can be applied
for a 20 s spiral, providing considerable dose reserves
even for adipose patients. As an example, in the Tho-
rax Combi protocol (120 kV, 45 mAs, 0.5 s rot, 16 x
1.5 mm, pitch 0.75) a scan range of 150 mm can be
covered in 5.17 s and dose can be increased up to
200 mAs without reduction of the table feed.
