The first High definition, Low Radiation CT Scanner in London at The Princess Grace Hospital

High Definition

The Discovery CT750 HD is the world’s first high definition CT scanner. It will set the new standard for CT clarity, delivering the vision and the tools to allow clinicians to diagnose quickly and confidently. Increased Image Quality at lower doses and new CT growth applications give you new insights and helps you to diagnose with greater speed and confidence.

At its heart is the first new detector material in 20 years; one that is, quite literally, a gem. GE engineers discovered that, by changing the molecular structure of real garnets, they could develope a scintillator capable of delivering images 100 times faster, with up to 33% greater detail throughout the body and up to 47% greater detail in the heart.

Dose Reduction

In short, it brings faster, clearer images into today’s demanding health care environment without sacrificing the element patients and clinicians demand most: radiation dose reduction. Though the laws of physics typically demand an increase in dose for each increase in image quality, GE Healthcare has engineered an exception. CT750 HD improves image quality while reducing dose by up to 50% across the entire body and by as much as 83% for cardiac scans. In addition to the new Volara DAS which uses hardware to reduce dose and improve IQ by reducing noise and software denoising filters and additional bow tie filters GE are the first to introduce the ASIR reconstruction which lowers noise so that you can lower patient dose by up to 50% and maintain the same image quality and improve low contrast detectability by 40%.

In addition to providing fine detail, allowing clinicians to see objects as small as a grain of sand, CT750 HD’s improved spatial resolution allows it to reduce calcium blooming artifacts. Because of this, accurate stenosis quantification is possible. In bench testing, it was able to accurately measure 75% stenosis on a 3mm vessel within 100 microns. It also benefits from improved low contrast detection (LCD), a measure of the amount of contrast needed to image a given object at a given dose. CT750 HD bench tested with a 40% LCD improvement.
