• Exclusive 1-Click Calcifications removal providing side-by-side display of Vessels in 3DMIP with and without calcifications for direct access to calcified plaques effect on vessel lumen
• Easy visualization of vascular structures in 3D MIP or Colored Volume Rendering
• Precise localization of pathologies thanks to bone landmarks displayed in Bone Transparency views, with or without calcifications

CT Perfusion

Functional CT Imaging. Provides means to determine extent of perfusion disturbance (Maps of Cerebral Blood Flow & Volume, and Mean Transit Time) access to Patient List, Viewer and 3D Advanced Applications

Benefits:

• Rapid, non-invasive tool that supports effective differential diagnosis of brain perfusion disturbance.
• Arterial inflow and venous outflow analyze for the calculation of the parametric image.
• Color tells the tale… Flow, Volume, Transit Time.
• Helps improve patient planning and management when every second counts.

Features:

• Cine scan at a single or dual contiguous slices location, for 20-40 seconds with intravenous peripheral injection of a relatively small amount of contrast at low injection rate.
• Images reconstructed as a time series.
• Automatic Vein and artery detection.
• Because of the many intricacies of hemodynamics, CT Perfusion from GE analyzes both arterial inflow and venous outflow for the calculation of the parametric image. This eliminates the standard assumptions about vasculature in the brain that introduce variability into the blood volume measurement.
• Provides accurate assessment of local cerebral blood volume (CBV), blood flow (CBF), mean transit time (MTT).
• Supports parametric image creation, overlay of parametric image onto reference image, definition and plotting of time-intensity information.

Clinical Applications:

• CT hemodynamics of cerebral circulation studies.
• Tracking drug therapy for hypervascular cerebral tumors.

Since CT is the diagnostic method of choice in many acute situations, CT Perfusion is the logical next step to quantify your patient's condition quickly-so clinicians can begin appropriate treatment.

CT Perfusion offers a clear opportunity to expand your CT capabilities to provide valuable information to referring clinicians, and excellent service to patients. With CT Perfusion, one scanner does it all.

SmartScore

Coronary Artery, Calcification Scoring package.

Benefits:

• Calculation of volume/density for areas of coronary artery calcification.
• Display of a score for each coronary region and image location where scorable pixels were highlighted.
• Provides five different methods to quantify the amount of calcification in the coronary arteries (AJ130, AJ90, Linear, Mass, Volume).

• SmartScore Option for HiSpeed CT/I, CT/I Pro and LightSpeed Advantage Scanner Systems is designed for computing coronary artery calcification scores from standard single-breathhold helical scans using the standard Agatston/Janowitz AJ) Method with a modified threshold.
• Standard helical images acquired in a single breathhold. The images are reconstructed at very short intervals (e.g.: 0.1 to 0.3 mm). A segmented reconstruction is used for this.
• Simultaneous to the acquisition, the EKG waveform of the patient is monitored and recorded. The images and the EKG data are forwarded to the Advantage Workstation for processing.
• By using the EKG waveform, the user can automatically or manually select images from within particular portions of the cardiac cycle.
• Once image selection is completed, a MIP image is generated using all the selected axial images. Candidate calcified regions are highlighted on the axial and MIP images by using a built-in threshold value. The user then interactively defines the appropriate lesions by using an intuitive ROI tool. Single-click region grow and rectangular ROIs are available, and multiple ROIs can be selected. Each ROI can be assigned to the desired artery (RCA, LMA, CX, LAD, and PD) simply by selecting the corresponding button.
• A screen save version of the output report is also generated. This and the selected images are saved as a new series.

Clinical Applications:

• Coronary calcification, along with other patient risk factors, can be used to aid physicians in assessing the overall risk factor of coronary artery disease.

Bone Mineral Densitometry

Bone Mineral Densitometry (BMD) is designed to facilitate bone mineral density measurements within vertebral bodies. It is applicable to assess changes in bone mineral content over time

Benefits:

• Fast, very user-friendly software: less than one minute to analyze bone density.
• Lots of standardized processes, not operator dependent.

Features:

• Automatic phantom and trabercular bone software places ROIs in the phantom samples and trabercular region of the bone without operator interaction. Software automatically checks and measures various CT scan parameters. KV, FOV, table height, recon algorithm, etc. are known variables affecting precision in QCT. Phantom position and table height are measured automatically on all scans to ensure reproducibility.
• Patient database is fast and allows serial study comparisons of BMD changes in mg of calcium hydroxyapatite equivalence and percent change on repeat exams.
• BMD results are plotted on a color clinical report with normative data graph and the serial graph. The clinician summary comments can be customized and automated for fast exam reporting.
• Scanner Standardization using the QA torso phantom and QA software module allows normalization of CT scanner response. The database, phantoms and software survive scanner change.
• CT scanner is not tied up during analysis. The QCT data acquisition typically takes place in less than 2 minutes.
• 3D data allows isolation of a volumetric ROI of pure trabecular bone for the highest sensitivity and accuracy.
• Fast patient throughput of any QCT system. Fast, easy to use software allows analysis in less than one minute, with minimal operator interactions.

Clinical Applications:

• Accurately measures bone loss/gain over time. Provides normative data to track osteoporosis risks.
• Allows for patient monitoring to assess response for therapy.
• Accuracy improved by scanning BMD pad and patient at the same time.

DentaScan and DentaScanPLUS

DentaScan and DentaScanPLUS create a comprehensive set of cross-referenced composite axial, panorex and oblique planar reformations of the mandible and/or maxilla. This tool is for planning mandibular and maxillary or dental implant surgery. AW 4.1 runs on a robust LINUX architecture

Benefits:

• Expands patient referral base to dental practices.
• Easy-to-use, post-processing software almost runs itself.
• Scanning techniques are very quick with low tube requirements, no contrast, very low dose.

Features:

• Axial or helical CT data is reformatted to display four images per screen for the mandible and maxilla.
• Oblique images permit visual inspection of cortical bone and alveolar nerve for optimal implant placement.
• Multiple (5 or 9) panorex images demonstrate pathology when needed, along with the nerve canal. Oblique and panorex reformations are cross-referenced to each other and to the original CT images.
• The oblique and panorex curves are user defined using the AW mouse (up to 100 points per panorex curve).
• User selectable distance between oblique reformations (from 1-10 mm).
• A mm scale is displayed to allow direct measurement.

Clinical Applications:

• Accurately measures bone loss/gain over time. Provides normative data to track osteoporosis risks.
• Allows for patient monitoring to assess response for therapy.
• Accurately improved by scanning BMD pad and patient at the same time.
