All-Digital Cardiology
The GE Innova 2000 uses the Revolution™ flat panel digital detector to replace Image Intensifier and video camera image chains for a new level of visibility of anatomy and interventional devices in very low dose fluoroscopic applications.
This is achieved through both the detector's high DQE and very wide dynamic range.
Scientific studies with GE Advantx Vascular Systems demonstrate the clinical benefits of 3D vascular imaging.

Integrating a Flat-Panel X-ray Fluoroscopy System into an Open MRI System: Technical Considerations
Dual modality imaging- a system enabling both x-ray fluoroscopy and MRI in a single exam, is investigated for image guided interventions. The result showed that the X-ray imaging performance was not appreciably affected by the presence of the main magnetic field when alignment between the anode-cathode axis and the main B field was maintained.

Dose-reduction Potential of Reduced Frame-rate Fluoroscopy and Adaptive Frame Averaging in an Observer-performance Phantom Study
This phantom study examined the possibility of reduced exposure using fluoroscopy without compromising observer performance in the detection of low-contrast stationary structures and high-contrast moving structures. The results suggested that use of 15 pps and the use of adaptive frame averaging, which may offer dose reduction for the detection of stationary structures.

The digital flat-panel detector imaging system reduces radiation exposure compared to conventional systems
The operator dose was compared between a digital flat-panel based cardiology system and a conventional II system using an anthropomorphic phantom. The digital cardiac system was one-third the dose of the conventional system in both cine and fluoroscopy modes.

Estimation of X-ray Patient Thickness by Flat-Panel Cardio-Vascular X-ray Systems Using Neural Network
The paper described a method for estimating the X-ray Patient Thickness by flat panel Cardio-Vascular x-ray systems with Copper Spectral Filtration based on Neural Network. The result showed good accuracy that allows better optimization of the x-ray technique for any patient size.
