GE Healthcare offers a wide range of products for interventional procedures, including our Innova* X-ray system. This family of single and biplane imaging systems offers excellent image quality with industry-leading Detective Quantum Efficiency (DQE) for a wide range of interventional procedures. An integral component of these products is the ability to optimize the radiation dose based on the needs of the patient, helping to enable clinicians to achieve the appropriate balance of radiation exposure and image quality in interventional care.
GE Healthcare’s Innova* imaging systems, featuring DoseSense, enable clinicians with advanced capabilities to manage dose based on the needs of the patient and can provide the clinical image quality needed to help facilitate confident decision making during interventional procedures.
Innova imaging systems are built on three key, innovative GE Healthcare technology pillars designed to maximize dose efficiency, reduce dose and simplify dose management. These pillars include a variety of proprietary technologies.
The proprietary Innova flat-panel detector offers the industry’s highest Detective Quantum Efficiency (DQE), a parameter internationally acknowledged as an index of detector performance in contrast- and dose-limited imaging performed in clinical studies. High DQE enables better quality images at the same dose, or the same quality image at a lower dose.
The high power and heat dissipation capability of the Innova X-ray tube enable spectral filtration for X-ray beam hardening to deliver a highly monochromatic and efficient beam. A harder X-ray beam helps avoid unnecessary absorption by the body, thereby helping to minimize unnecessary radiation.
Copper spectral beam filters located in the collimator are available in several thicknesses and are under automatic system control for versatile, uniform beam hardening performance. Combined with the tube technology, efficient radiation dose management can be achieved.
A variety of Innova dose reduction features, all optionally controllable from procedure table, can also help clinicians reduce radiation dose exposure during procedures.
Dynamic Range Management is designed to help minimize problems with image blackout and burnout by extracting relevant image information, transforming background thicknesses, and then restoring structures of interest.
Radiation dose-saving features include Fluorostore, which stores, displays, and plays loops of the last 450 fluoroscopic images at the push of a button. This streamlined image review helps avoid additional images and dose exposure. And finally, InnovaSense patient contouring technology automatically minimizes detector-to-patient distance to help minimize patient skin dose.
Innova’s smart system design integrates radiation dose management tools into the procedural workflow. Offering automation and flexibility, these tools can help clinicians adapt to a wide range of imaging situations.
The Automatic Exposure (AutoEx) control system is designed to automatically and continuously adapt to help keep patient radiation dose at optimum levels for the image quality needed. With Innova Dose Personalization, clinicians can choose from multiple different AutoEx default preferences, or program from any of these in any protocol, to enable multi-procedure, multi-user customization. Direct dose management allows clinicians to instantly reduce dose.
Together, the AutoEx control system and the Innova Dose Personalization features provide a ~24:1 range in fluoro and ~6:1 record dose rate adjustment. Linear Dose Reduction and Balanced IQ & Dose Reduction Strategies allow for step-by-step dose reductions to provide an approximate 24:1 range in fluoro dose rate adjustment when combined with AutoEx Preferences.
Innova dose monitoring and reporting capabilities can help clinicians closely track and manage dose exposure. Clinicians can also view dose profiles and dose-by-procedure reports, identify high-dose cases, and help ensure patient radiation dose levels stay within dose reference levels. Innova Dose Reports (optional) provide an easy, automated way to track system and dose utilization details at the point of care. Critical information, collected remotely via the InSite* broadband connection to GE Healthcare, is combined in comprehensive reports to illustrate procedure utilization, dose usage details per procedure, monthly dose utilization trends, benchmarking and more. Clinicians can receive via e-mail near real-time alerts that extensively detail high-dose exams, including the innovative cumulative dose incidence map which uses gantry angulations to estimate potential hot spots.
