Moving Phantom for Residual Image Evaluation KS-III - PH-81 - Kyoto Kagaku
Dynamic X-ray and fluoroscopy image-lag quality control
Setup example. Acrylic absorption/scatter plates shown are not included.
The PH-81 Moving Phantom for Residual Image Evaluation KS-III is a powered dynamic quality-control phantom for X-ray and fluoroscopy systems. Signals on a motor-driven rotating acrylic disc support evaluation of residual images and instantaneous image lag under moving-image conditions.
The phantom helps users determine acquisition conditions and adjust image-processing and noise-reduction parameters for moving images, including cardiovascular and interventional radiology (IVR) fluoroscopy applications.
