** Option† In clinical practice, the use of ASiR may reduce CT patient dose depending on theclinical task, patient size, anatomical location, and clinical practice. A consultation with aradiologist and a physicist should be made to determine the appropriate dose to obtaindiagnostic image quality for the particular clinical task.

†Option. For 32-slice version, it enables 64 reconstructed slices per axial rotation.

The best of technology,simple to applyThe Optima CT660 brings you our latest CT workflow innovations for improved easeof use. From our proven HD technologies, we added ASiR to help you deliver dosereduction across anatomies. The system solution also features full capabilities inadvanced applications such as cardiac, oncology, angiography, and dynamic imaging.

Power and performanceThe Performix* 40 tube, backed by apowerful 72-kW generator, deliverspeak mA capability of up to 600 mA.This helps you:

• Image small structures and seefine detail.

• Examine large patients withouttradeoffs on image quality and speed.

• Experience less acoustic noise incardiac studies and other faster-rotation scans.

The console is built with advancedcomputer technology andminiaturizationfor optimized workflow, fast imagereconstruction, and improved reliability.The quad-core CPU easily processesadvanced iterative reconstructiontechniques. Simultaneous data transferhelps optimize and streamline workflowbetween the Advantage Workstation*,PACS, and external devices such asCD writers.

Efficient imagingThe 40-mm wide V-Res* detectoracquires data at 0.35-mm microVoxel*resolution through GE innovations,such as:

• A fast and efficient HiLight* scintillatorwith 98% absorption efficiency.

• High-density interconnects.

The Optima CT660 image chain ispowered by the Volara*XT DataAcquisition System (DAS).


Speed and spatial resolutionGE helical reconstruction technologiesand crossbeam correction work togetherto deliver 0.35-mm isotropic spatialresolution. Conjugate cone-beam filteredback projection utilizes two sets ofcounter-opposed projections to provide128 distinct projection measurementsper rotation for axial and a helicalacquisitionmode. For cardiac acquisitions,fast rotation speed provides excellenttemporal resolution (44 msec).

Low dose, low stressNothing matters more than patients’ welfare. TheOptima CT660 provides information to clinicians tohelp in efficient and definitive diagnoses in low-doseexams while patients stay calm and comfortable.

** Option† In clinical practice, the use of ASiR may reduce CT patient dose depending on theclinical task, patient size, anatomical location, and clinical practice. A consultation with aradiologist and a physicist should be made to determine the appropriate dose to obtaindiagnostic image quality for the particular clinical task.

ASiR** inside:A leap ahead in dosemanagementGE’s ASiR dose-reduction technology:A reconstruction technology that mayenable reduction in pixel noise standarddeviation.

ASiR provides these important imagingbenefits:

• ASiR may allow for reduced mA inthe acquisition of diagnostic images,thereby reducing the dose required.†

• ASiR may enable improvement inlow-contrast detectability.†

• ASiR may help clinicians achieveconfident diagnoses with lower dose†

Comprehensive dosereduction with Optidose*Dose reduction with ASiR is combinedwith GE’s proven Optidose technologythat delivers dose reduction at thesource. It includes SmartTrack* dynamiccollimation that keeps the X-ray beamtightly focused on the active detectorcells, as well as 3D mA automaticmodulation, ECG dose modulation,and X-ray filtration which is tailoredfor small to large patients.

Conventional CT image recontructiontechniques are simple and fast, but havelimitations, as they are sensitive to noiseand artifacts.

ASiR extracts noise by modelling its rootcauses for each patient and applicationtype.


Dose checkThe dose check feature provides toolsto notify and alert the operatingpersonnel, generally technologists, thatprepare and set the scan parameters,prior to starting a scan, whether theestimated dose index is above the valuedefined and set by the operating group,practice, or institution to warrantnotification to the operator. The dosecheck feature is designed to complywith the NEMA XR-25 standard.

A comfortable experienceThe Optima CT660 enables short scantimes with 40-mm thin-slice acquisitionsfor reliable studies. Technologists canpersonalize exams by displaying thepatient’s name on the new 12-inchtouch-screen gantry display. The videoof relaxing scenes or cartoons can havea calming effect on children or patientsof all ages. An automated voice systemprovides the ability to give instructionsin the patient’s own language. In thelow position, the exam table helps withaccess for patients in wheelchairs.


Complete exams with easBy listening to technologists and radiologists, GE has created an intelligentCT scanner with a workflow for streamlined use that helps optimize patientthroughput.

Enhanced tableThe table allows patients as heavy as500 lbs to be imaged through a longscannable range. The bed providesautomatic positioning according tothe type of exam, reducing manualpositioning and streamlining workflow.Users can position the table by selectingthe exam type from the touch screen,then pressing the foot pedal. The displayshows pictures that help the technologistand patient understand the correct examposition, making exams more personal.

User-friendly consoleThe Optima CT660 workspace providesflexibility and comfort, whether sittingor standing. The console is noticeablyquieter than in the past, to provide abetter work environment. The graphicaluser interface, common to all GE CTsystems, puts automated processingat your fingertips.


e and confidence

Synchronized injectionThe CAN Cia425 Xtream IntegratedInjector** provides synchronized start ofscan and injection from the CT operatorconsole. Synchronization of the start ofscan with the start of injection providesincreased opportunity for successfulcontrast bolus timing. It also providesthe ability to set the contrast injectionparameters and to synchronize theparameters between the scanner andinjector as part of the CT scan protocolfrom the console interface. This providesconsistency of user-entered parametersand reduction in the opportunity for error.

Personalized touchesOne-Touch set-ups allow you topersonalize image presentation toindividual physician preferences, so thatadvanced processing, volume-renderingattributes, multi-planar reformats, andimage sizing are automatically appliedas the patient series opens.
