FEATURES

Designed to help advance precision health and support greater theranostic capabilities in nuclear medicine

StarGuide provides accurate quantitation to help clinicians make personalized care decisions and treatment response assessments that are at the heart of Theranostics by striking the right balance of energy resolution and spatial resolution.
¹⁷⁷LU IMAGING

Unlock the potential of theranostics and highly personalized care

Each of StarGuide’s 12 CZT Digital Focus Detectors supports a wide energy range capable of imaging the dual energy peaks of tracers used in Theranostics, such as the 113 keV and 208 keV emission peaks of 177Lu used to diagnose and evaluate treatment response for prostate cancer2. StarGuide is optimized for 177Lu imaging, enabled by its improved energy resolution, system sensitivity, and system planar resolution for 177Lu high and low energy peaks as compared to a NaI system3. This enables 177Lu imaging without the need for collimator exchange — typically needed in dual head cameras — simplifying day-to-day clinical workflow and patient scheduling.
OPTICAL SCOUT

Perform preliminary, optical scans in seconds

StarGuide’s Optical Scout feature represents a genuine breakthrough in wholebody scanning and charts the path toward high quality clinical images. Located within its 80 cm bore, it performs an optical scan that creates an accurate topographical map of the patient, quickly and accurately scanning body contours to assure fast and safe transition from one imaging position to the next.

After processing the contour data, StarGuide's detectors and table are automatically positioned in close patient proximity for each bed position before beginning the clinical scan. With patient safety of paramount importance, each detector also contains a pressure sensitive cover, stopping motion if it is triggered.
3D Imaging

Our most advanced CZT Digital Focus Detectors

StarGuide’s Digital Focus Detectors are designed to propel SPECT imaging to new heights in performance by maximizing the amount of information to help you gain true insight into the patient condition. After optimizing the detector and bed positions from the Optical Scout data, StarGuide’s constellation of 12 slim Digital Focus Detectors orbit the body as closely as possible, and from all necessary angles, to scan the target area — and not the air surrounding the patient. The result is a high-resolution scan and minimization of patient time on the camera. CZT detector technology features a higher count rate over conventional detector technologies. StarGuide’s intrinsic count rate is greater than 700 kcnts/second with no detector saturation or resulting dead time.

SWIFT PLAN

Swift Plan workflow is designed to simplify clinician interactions with a scanner

By leveraging proven GE Healthcare innovations like its interactive table ruler and our advanced automation robotics, then combining them with new innovations like our intuitive bedside display and Optical Scout, Swift Plan quickly becomes an extremely capable and user-friendly productivity enhancer. Swift Plan with SmartConsole automates SPECT/CT reconstruction, simplifies complex hybrid and quantitative protocols, optimizes image quality with retrospective processing features, reduces errors, allows operators to see images at the scanner console, and enables physicians to review scans remotely. Even with a long list of capabilities, the learning curve for Swift Plan is remarkably short.
SMARTCONSOLE

SmartConsole is optimized to host our latest reconstruction algorithms and applications, plus it helps you seamlessly clarify and share patient data

SmartConsole is our latest network-capable image processing sub-system for Nuclear Medicine that enables you to automate SPECT/CT reconstruction, simplify complex hybrid imaging and quantitative protocols, and generate high-quality hybrid images so you can make informed decisions that lead to quantifiable results. SmartConsole includes FAME post-processing, which integrates the CT anatomical bone information into the SPECT bone image processing. When used on StarGuide images, the lesion detectability is improved, which helps increase diagnostic confidence4.
Q.CLEAR

Full convergence reconstruction

The Q.Clear reconstruction algorithm represents a significant step forward for use in SPECT imaging, including in the assessment of treatment response in addition to the diagnosis and staging of disease. This advancement is made possible by suppressing noise to provide outstanding quantitation accuracy without sacrificing StarGuide’s ability to accurately determine lesion size and volume.
FEATURES

A better patient experience by design

Reliable scheduling

Replace planar exams with the predictable, repeatable scan times of 3D-only protocols which may minimize the need for additional views, reduce scheduling overruns and shorten patient wait times.

Scanning comfort

Swift Plan minimizes the time the patient spends motionless on the camera, helping lower the stress for patients with certain anxieties.

Higher sensitivity⁵

Leverage StarGuide’s higher system planar sensitivity and volume sensitivity, an important factor in NM imaging for enabling dose and time reduction.

Fewer rescans

Optical Scout, Swift Plan, StarGuide’s image processing engine, and Focused Imaging are important factors in helping reduce the need for inconvenient and anxiety-inducing rescans.

Rapid contouring

Optical Scout’s contour scans help minimize the likelihood of detector contact while enabling close patient proximity.

High-resolution images

Exceptional image quality and the enormous amount of high-resolution data that StarGuide generates with each scan give physicians a clear image.

Multiple tracers

StarGuide has the ability to simultaneously image multiple tracers in a single scan that may otherwise involve multiple patient visits and, in relevant cases, multiple patient sedations. This inherent temporal registration helps increase the confidence in differential diagnosis.

The resolution to see more, learn more

The CZT material at the heart of each Digital Focus Detector provides an inherently high contrast-to-noise ratio. Its 2.46 mm² pixel size and 8 mm spatial resolution6 deliver the clarity you need to detect, locate, and quantify diseases at an early stage – helping to open the door to more effective treatments and improved patient outcomes. StarGuide delivers a remarkable 5.9% energy resolution when scanning ⁹⁹ᵐTc, and <5% energy resolution when scanning 177Lu at its 208 keV peak. With such superb energy resolution, StarGuide gives you the ability to effectively differentiate between simultaneously acquired isotopes with smaller differences in peak energies.

Image a wide energy range

The ability to image both low and medium energy isotopes in a single scan with exceptional levels of spatial and energy resolution is what makes StarGuide a great tool for both clinical and research environments. The proprietary design of our 7.25 mm thick CZT semiconductor crystal makes the module capable of supporting up to 500 keV.*
*StarGuide's CZT module only.

Take a closer look where needed

Focused imaging gives you the ability to target a specific volume of interest (VOI) within the patient’s body and improves image quality within that VOI as the Digital Focus Detectors image that volume. StarGuide alters the detector sweep to spend more time focusing on the designated area to produce high-quality, data-rich imagery with no increase in scan time.

Analyze flow in greater detail

StarGuide’s ring of Digital Focus Detectors enables Dynamic SPECT acquisitions1 with high temporal resolution in as fast as 1 second. Fast temporal resolution is an important factor in imaging bolus injection and flow measurements.

Personalized patient exposure

StarGuide’s CZT technology is pivotal to minimizing the patient’s exposure to SPECT’s radioactive processes because its higher system planar sensitivity and volume sensitivity is an important factor in NM imaging for enabling dose and time reduction5.

Dual Channel collimation

StarGuide’s exclusive Dual Channel collimator enables a balance between sensitivity and resolution across low and medium energy ranges. Its design combines shorter septa and tungsten construction to deliver a remarkable 8.0 mm NEMA planar resolution and 4.5 mm Central SPECT resolution with scatter. The improved SPECT resolution enables sharp images for better visualization of fine anatomical details, which can help physicians to detect diseases at an earlier stage7.
