"And look at this," he added, pointing to Brett Simpson as he ducked into an eight-foot high tube.
Among these, some have suffered significant tubes deformation and other defects related to heat loads in high tube walls.
Hypervascular liver tumors: low tube voltage, high tube current multi-detector row CT for enhanced detection--phantom study.
Corresponding ball and bond type for high, tube for medium and wireframe for low layers.
CONCLUSION: The CNR of simulated hypervascular liver lesions can be substantially increased and the radiation dose reduced by using an 80-kVp, high tube current CT technique.
Additionally CT acquisition parameters include high tube charge, lower pitch, and thin sections, also with the consequence of increased dose.
Similar to rapid kVp switching, the low and high tube voltage output is limited to the same filtration [32].
These were the only authors using a tube current of 140 kV, together with a high tube current product of 380 mAs for the imaging of pregnant patients.
The sheet resistance of SACNTs in this work, measured by four-probe method, was about 1,000 Ω due to the relatively high tube-tube junction resistance.
While the sheet resistance of Au-coated SACNTs decreased to 130 Ω due to the high conductivity of the metal which could avoid the typically high tube-tube junction resistance.
Using the CT fast protocol with low tube current or the CT slow protocol with high tube current on the Brightview XCT cameras resulted in almost identical contrast recovery values.
