Product Description
Performance Evaluation and Quality Assurance of Imaging Systems Applied to Axial CT Scanning and Spiral CT Scanning
Comply with GB/T17589-2011 Image Quality Assurance for X-ray Computed Tomography Equipment;
Conform to JJG 1026-2007 "medical spiral CT" verification procedures
The CT performance module is a modular design and consists of four detection modules:
★YDP-1: measurable layer thickness, CT value linear (6 CT values):
Diameter 15cm, thickness 2.5cm
Two sets of 23 ° metal slashes (X direction, Y direction) are embedded for layer thickness measurement.
Six small cylinders with different densities are embedded to measure 6 CT value lines.
★YDP-2: can be measured high contrast resolution:
Diameter 15cm, thickness 4cm
22 groups of high density line pair structures were distributed radially. The spatial resolution corresponding to each line pair from low to high is
(1 lp/ cm-21LP/cm) (5mm-0.24mm)。
★YDP-3: Can measure low contrast resolution:
Diameter 15cm, thickness 4cm
Inner and outer two groups of low density pore size structure (radial distribution)
Inner hole array: contrast 1.0%; diameter 3, 5, 7, 9mm
Outer hole array: contrast 0.3%, 0.5%, 1.0%; diameter 2, 3, 4, 5, 6, 7, 8, 9, 15mm
★YDP-4: Field uniformity and noise can be measured:
15cm in diameter and 4cm in thickness Composed of water equivalent tissue material for measuring uniformity and noise
★YDP-5: water mold body (option)
The real water filling module, one imaging can get the CT value of the machine water. There is no need to use a separate water phantom.
