Spatial and Z-axis Resolution Inserts
The inserts can be used inside or outside the ImPACT CTDI phantom
outside - more convenient
- More accurate alignment
- holes give different scan
- Reduce the dynamic range in
the image and the appearance of artefacts around the wire
Notes:
- The new spatial and Z-axis resolution inserts can be used inside or outside the Impact CTDI phantom.
- We often use them outside the phantom for convenience
- However, They can be used inside the phantom for more accurate alignment and positioning in the scan plane and to reduce the dynamic range in the images and reduce the appearance of artefacts around the wire or disk.
