• Usable on all standard and helical scanners
• Background = liver
• Spheres = 5, 10, 20 ctu below background
• 3 reference plugs for each material used as spheres
• Valid contrast at all energy settings
• Compact
• Indestructible
The Helical CT Phantom is designed to test scanning protocols to verify that small low contrast lesions will be detected. The phantom permits complete testing of low contrast lesion detection when scan parameters are varied. These parameters include collimation, pitch, reconstructed field of view, reconstruction algorithms, z-axis interpolators, kVp, mA, and rotation time. Testing can be applied to protocols designed for head and abdomen.
Contains clinically-relevant spherical targets that are 5, 10, and 20 HU below the liver equivalent background matrix.
Item 680-061 Includes the following:
• Phantom Body
• Low Contrast insert (see dimensions)
• Carrying case which can be used as a phantom support during
scanning procedure
• Instruction manual
