CT performance phantom G500
CT performance water model is suitable for measurement and testing units, acceptance/status detection evaluation of CT scanning systems.
Detection indicators: measurable spatial resolution, low contrast resolution, CT value, noise, uniformity, layer thickness, CT value linearity, positioning light. Suitable for spiral CT detection.
These modules are still suitable for continuous 20cm space.
The selective testing module and its standards for the phantom are often used for many experimental measurements. Including
Evaluation of the following parameters:
⚫ Scanning slice (layer thickness and slice)
⚫ High contrast spatial resolution (up to 20 or 21 pairs/cm)
⚫ Mold position
⚫ Patient positioning system examination
⚫ Low contrast
⚫ Slice low contrast inspection comparison
⚫ Spatial uniformity
⚫ Scan Increment
⚫ CT system noise (accuracy)
⚫ Circular symmetry
⚫ Linear photosensitivity
⚫ Pixel (matrix) size
⚫ Point stretching function and modulation transmission function
