CCT189 low contrast body phantom

CCT189low contrast body ghostCCT189The Phantom has eight contrast rods. Four contrast rods long40mm, each of these rods has a different diameter and nominal contrast. Samples from each batch of selected contrast rods in our in-houseCTTest with multiple scans on the scanner. Scans of the contrast rod are analyzed through automated analysis. And these contrasts are measured as intrinsic. For a more precise assessment of your phantom. We recommend averaging multiple scans. The mark and contrast value and diameter are14HUwith3mmTrue diameter comparison,7HUwith5mmdiameter comparison,5HUwith7mmdiameter comparison,3HUwith10mmDiameter comparison (HUrefer toHounsfieldunit orCTnumber).

In order to ensure the consistency of the comparison, each comparison40mm rod and10mm rods are from the same casting batch. The phantom has four alignment points, which help position the phantom. There are three points defining the flat alignment of the mounting end10mm long,15mm diameter contrast rod. One of the dots is on top and the other two are on the sides of the phantom. The fourth point is also at the top of the phantom and is connected to40mm contrast rod center alignment。
