The Optima CT660 system helps you deliver competent, personalized care that helps fulfill your mission and please your patients. One look at the sleek, compact design tells you this CT system is different. This new-generation, intelligent Volume CT scanner combines the innovations from our Discovery* and LightSpeed* families. You get fast, high-quality acquisitions at optimized dose for patients young and old, large and small, across a wide spectrum of procedures: cardiac, angiography, brain, chest, abdomen, orthopedic, and more.
Technologists and radiologists benefit from ergonomic features and numerous enhancements in workflow efficiency and diagnostic power. The compact footprint lets the system fit your available space, while a modular design helps you choose capabilities to meet today’s budget and expand as you grow.
The Optima CT660 is also environmentally friendly with a design for refurbishment and end-of-life recycling, and with electronics innovations that may cut power onsumption compared to previous GE technology by 60% using the energy-saving mode. Look closely and you will see how the Optima CT660 is designed to help you provide great care to your patients by delivering low-dose, high-quality imaging.
The Optima CT660 brings you our latest CT workflow innovations for improved ease of use. From our proven HD technologies, we added ASiR to help you deliver dose reduction across anatomies. The system solution also features full capabilities in advanced applications such as cardiac, oncology, angiography, and dynamic imaging
The Performix* 40 tube, backed by a powerful 72-kW generator, delivers peak mA capability of up to 600 mA. This helps you
» Image small structures and see fine detail.
» Examine large patients without tradeoffs on image quality and speed.
» Experience less acoustic noise in cardiac studies and other faster-rotation scans.
The console is built with advanced computer technology and miniaturization for optimized workflow, fast image reconstruction, and improved reliability. The quad-core CPU easily processes advanced iterative reconstruction techniques. Simultaneous data transfer helps optimize and streamline workflow between the Advantage Workstation*, PACS, and external devices such as CD writers.
The 40-mm wide V-Res* detector acquires data at 0.35-mm microVoxel* resolution through GE innovations, such as:
» A fast and efficient HiLight* scintillator with 98% absorption efficiency.
» High-density interconnects.
The Optima CT660 image chain is powered by the Volara*XT Data Acquisition System (DAS).
Speed and spatial resolution GE helical reconstruction technologies and crossbeam correction work together to deliver 0.35-mm isotropic spatial resolution. Conjugate cone-beam filtered back projection utilizes two sets of counter-opposed projections to provide 128 distinct projection measurements per rotation for axial and a helical acquisition mode. For cardiac acquisitions, fast rotation speed provides excellent temporal resolution (44 msec).
Enables 128 slices per rotation on a 64 slice system in axial scanning modes and delivers improved Z-axis visualization performance relative to non-overlapped reconstruction.
Nothing matters more than patients’ welfare. The Optima CT660 provides information to clinicians to help in efficient and definitive diagnoses in low-dose exams while patients stay calm and comfortable.
GE’s ASiR dose-reduction technology: A reconstruction technology that may enable reduction in pixel noise standard deviation.
ASiR provides these important imaging benefits:
» ASiR may allow for reduced mA in the acquisition of diagnostic images, thereby reducing the dose required.
» ASiR may enable improvement in low-contrast detectability.
» ASiR may help clinicians achieve confident diagnoses with lower dose.
Dose reduction with ASiR is combined with GE’s proven Optidose technology that delivers dose reduction at the source. It includes SmartTrack* dynamic collimation that keeps the X-ray beam tightly focused on the active detector cells, as well as 3D mA automatic modulation, ECG dose modulation, and X-ray filtration which is tailored for small to large patients.
Delivering true 40-mm coverage per rotation, featuring a temporal resolution down to 44 ms, the Optima CT660 is designed to scan the heart in five beats. Its ample tube power combined with ASiR delivers the image quality demanded, even with large patients.
40-mm Snapshot Pulse addresses the dose burden of traditional coronary CT angiography. With the X-rays turned on only during the requested cardiac phase, the technique can routinely reduce dose compared to traditional helical techniques. Real-time adaptive scan control helps avoid scanning during irregular beats and improves overall scan reliability. ASiR technology enables dose reduction across the body.
With consistent 0.625-mm data acquisition, there is no rade-off between speed and high resolution. Optima CT660’s speed and coverage may allow you to catch the arterial phase for assessment of most vascular segments. The Xtream Integrated Injector allows you to synchronize injection and acquisition parameters.
The Advantage Workstation cardiovascular system helps accelerate workflow with leading innovations in post-processing automation and reliability. With Autolaunch and Preprocessing, the system automatically prepares up to eight cases for reading, saving substantial time. In addition, zero-click bone removal automatically subtracts bones in angiography studies. Other enhancements include:
» Reliable coronary segmentation and tracking.
» Fully automated analysis of all four heart chambers.
» Automated vessel tracking and thrombus segmentation.
