GE Healthcare develops products based on the idea that both dose and
image quality are important factors in providing quality medical care.
To assist you in optimizing each CT exam for your patients, GE
Healthcare has innovated over the years, with Optidose technology and
iterative reconstruction techniques, to provide solutions to help you
To optimize imaging of the head and body in pediatric, small, medium, and large patients.
Advanced hardware and software for x-ray beam tracking minimizes patient dose.
Prospective Dose Display
CTDIvol, DLP (Dose Length Product), and Dose Efficiency display during
scan prescription provide patient dose
information to the operator.
Color Coding for Kids
This Color Coding system is incorporated into the protocol selection on
the operator’s console and is designed to facilitate pediatric emergency care
and reduce medical errors.
3D Dose Modulation
During the scan, real-time, 3D dose modulation helps deliver consistent
image quality because it automatically accounts for the changing dimensions of
your patient's anatomy.
Adaptive Image Filtration
Provides users the capability to reconstruct filtered images using
different steps of noise (pixel standard
deviation) reduction, this lower noise may allow a reduction of mA
while maintaining an acceptable level of image noise.
ECG Dose Modulation
For cardiac applications, prospective ECG dose modulation automatically
adjusts the mA to minimize the patient’s exposure to x-rays – reducing dose
during systolic phases of the cardiac cycle.
Volara* HD Digital Data Acquisition System (DAS)
Enables true high definition acquisitions with an 8-to-1
miniaturization delivering dramatic reduction in electronic noise for improved
low signal imaging performance and fast sampling rates.
Prospective axial ECG-gated cardiac acquisition protocol to complete
the scan via step-and-shoot mode with a potential for less dose compared to low
pitch helical technique (up to 83% less).
Volume Shuttle doubles Z-coverage to 80mm (128 slice width) for neuro
perfusion studies including angiographic information, which may enable lower
dose (up to 24% less) compared to a 40mm Cine protocol due to x-ray being
turned off during table moves.
Adaptive Statistical Iterative Reconstruction, advanced reconstruction
technique that may enable reduction in pixel noise standard deviation. ASiR may
allow use of a lowered mA protocol thereby reducing the required dose. ASiR may
enable an improvement in LCD.
DICOM Structured Dose Report
Reporting (DICOM) provides access to the CTDIvol and DLP with the patient
record prior, during and post exam.
Dynamic Z-axis Tracking
Provides automatic and continuous correction of the x-ray beam position
to block unused x-rays at the beginning and end of a helical scan to reduce
First Model-Based Iterative Reconstruction (MBIR) product. Our next
revolution in reconstruction innovation that may provide significant Image
Quality benefits, at lower radiation dose.
The cornerstone of a proactive radiation management program.
1.In clinical practice, the use of ASiR may reduce CT patient dose or improve LCD depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. ASiR dose reduction was measured on a standard 20cm water phantom. The test involved maintaining constant pixel standard deviation as the mA was reduced at 120 kVp.
2.In clinical practice, the use of Veo may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
