Eve Clear Scan e680

Compact and Mobile Single Digital Detector

The Eve Clearscan E680®:-

• Allows imaging close to the chest wall, thus minimising dead space.

• Portable gantry eliminating the need for installation or a dedicated exam room and allowing use at several points of care.

• Movable detector head allows imaging in all mammographic positions, plus selective study of hard-to-reach areas such as the axilla.

• May be located in or near the breast centre for same-day diagnostic imaging.

Digital Detector Technology:

• Lightning-Bright multi-crystal, wave-shifting array

• Light Guide – proprietary light concentrating optics

• Maxis high-density, high-resolution detector data point sampling system

• Smart-Logic – patented digital signal processing algorithm Proprietary Breast Positioning – Clear Shield

• Proprietary breast imaging paddle allows “see through” for easy positioning.

• The breast shield insert decreases scatter radiation from nearby organs improving image quality

• Stabilises the breast without painful compression

Collimator options:

• Low Energy General Purpose (LEGP) Collimator. Optimised to perform Molecular Breast Imaging including lymphatic imaging (lymphoscintigraphy).

• Slant 15 Collimator. This 15-degree slanted collimator minimises dead space along the edge of the detector, improving visualisation of lesions near the chest wall.

• Low Energy High-Resolution (LEHR) Collimator. Enhances thyroid imaging without the need of the pinhole collimator.

OPTIONAL - GammaLōc® BIOPSY system:

Lesion localisation accessory to the Eve Clearscan E680® enabling MBI guided breast biopsy.

Can also be used for other general molecular imaging applications, (please contact us for more details).

Compact and Mobile Single Digital Detector

The Eve Clearscan E750:-

Helps enable you to make critical contributions to breast-cancer care, from supplemental screening in dense breasts, to diagnosis and planning, through treatment monitoring. It provides consistently high sensitivity, even especially in patients with dense breasts, in a highly efficient and affordable device. Leading-edge, solid-state Cadmium Zinc Telluride (CZT) detectors are the primary enabler of this compact device compact device, allowing you to image the breast up close, right up to the chest wall, in standard mammographic views. Best of all, the Eve Clear Scan e750 is both patient and user friendly. It requires only light mobilisation pressure and offers efficiency in support functions from image sharing through calibration.

Main Features:

High-resolution, direct conversion, solid-state NM detector technology including:

• Miniature, high performance CZT semiconductor sensors.

• Dual-head configuration has aligned heads so that images can be combined and improve lesion detectability (even in the middle of the breast) or reduce acquisition time.

• Isotope uniformity and energy correction maps for all clinical isotopes

• Fully-registered collimator (collimator holes aligned to the CZT pixels) – maximizes sensitivity and resolution.

• Detector and collimator stationary during scan.

• Option to acquire & reframe time-sliced (dynamic) images.

• Improved energy resolution and scatter rejection compared to standard NaI(Tl) scintillation detectors.

• Direct conversion eliminates the need for PMTs and linearity calibrations.

• Pixel size optimized for resolution and molecular contrast sensitivity.

Digital Detector Technology:

With CZT, our detectors are so compact that they can image up close, providing major improvements in lesion detection. CZT provides outstanding image quality:

• Improved intrinsic resolution compared to traditional scintillation gamma

• Cameras.

• Spatial resolution better than 5 mm FWHM throughout the imaging volume (e.g. molecular resolution).

• Up to triple the sensitivity of conventional nuclear detectors.

• Degradation-free uniformity across the entire 24x16-cm FOV, right up to the edges.

And that these features translate into significant enhancement in lesion detectability. In a clinical screening trials of high risk dense breast populations with 6,000 women, MBI technology outperformed mammography in early detection and in finding more cancers; thus the need for multiple exams was reduced.

F.A.Q. - MBI System

How does MBI differ from other breast imaging tests?

MBI differs from other breast imaging modalities such as mammography and ultrasound in that it is a functional (metabolic) test rather than a structural (anatomic) test. Structural or anatomical imaging takes a picture of the tissue within the breast, both normal and abnormal, like cysts, glands, ducts, tumours or scar tissue. These tests are trying to find something that “looks” suspicious. MBI as a functional imaging procedure images cellular metabolism allowing physicians to see the metabolic activity of the tissue, and see if the tissue “acts” suspicious which can help to differentiate benign from malignant tissue since they often look alike on mammography or ultrasound.

What is the advantage of MBI?

Clinical studies have shown that MBI can detect cancers missed by mammography and ultrasound while leading to fewer benign biopsies than MRI. This seems to be especially true for patients with dense breasts and patients who have types of cancer that are difficult to detect, like lobular carcinoma.

How long does the MBI procedure take?

In general, four images are taken — two for each breast. Each view takes about 5 – 10 minutes to image. The procedure lasts from 45 minutes to an hour for all of the images to be completed.

Is the MBI procedure comfortable?

Only moderate pressure is required to help form and stabilize the breast for imaging with MBI, making it much more comfortable than a mammogram. Also, patients are seated comfortably through the entire procedure. Many patients comment that MBI is significantly more comfortable than mammography and MRI.
