Standard Protocol
Low frame rate protocol
Customized Protocol
This is the fluoroscopy protocol used routinely in most catheterization labs in the region. This includes fluoroscopy and cine image acquisition at 15 frames per second (FPS) at 8-inch mode. Virtual collimation and last image hold (LIH) will be used as needed. This protocol will be implemented for 6 weeks.
This will have fluoroscopy and cine image acquisition at 7.5 FPS at 8-inch mode with all other settings on factory default. Virtual collimation and LIH will be used as needed. This protocol will be implemented for 6 weeks as well.
This will have varying settings based on three weight based groups. Small (<60 kg), medium (60-85 kg), large (>85 kg). The variables changed are fluoroscopy dose per frame, fluoroscopy frame rate, image acquisition frame rate, thickness of the spectral beam filters, peak tube voltage and peak cathode current. Additional features will also be utilized including live zoom (1.4 factors with 12 inch field of view, FOV), fluoro store and Spot fluoroscopy. Virtual collimation and LIH will be used as needed. This protocol will be applied for 12 weeks.
