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 optimising 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 manage dose.
To optimise imaging of the head and body in paediatric, small, medium, and large patients.
Advanced hardware and software for x-ray beam tracking minimises patient dose.
Prospective Dose Display
CTDIvol, DLP (Dose Length Product), and Dose Efficiency display during scan prescription provide patient dose information to the operator.
Colour Coding for Kids
This Colour Coding system is incorporated into the protocol selection on the operator’s console and is designed to facilitate paediatric 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 minimise 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 miniaturisation 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
Dose 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 unnecessary radiation.
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.
