Radiation Dose Reduction Hardware: Inside Neusoft's Low-Dose CT Detector

NeuViz_16_DetectorsSo, you'd love to have the low-dose performance of a 64-slice CT scanner with iterative reconstruction (low-dose software), but adding one to your equipment stable is currently outside your budget? Fortunately, there's a solution that can fit the performance level you're after into a more manageable price bracket: the NeuViz 16 from Neusoft.

The first question that comes up after a statement like that is usually,  "How does a 16-slice CT scanner match the dose reduction capabilities of a 64-slice?" There are two ways to answer this...

The Quick Answer

Dose reduction software cannot replace dose-efficient hardware. If the hardware of a CT scanner is not designed to minimize dose, the software is actually fighting the inefficiency of the hardware.

The Technical answer

The detector is the heart of any low-dose CT design. The more efficiently and quickly the detector converts X-ray into a digital signal, the lower the X-ray dose that will be required to produce high quality images. Neusoft's NeuViz 16 CT detector is designed for maximum dose efficiency. This allows the system's dose reduction software to work alongside the hardware, not against it.

These detectors achieve lower doses through a number of design features, including:

•Optimized Geometry- Optimizing the tube to detector geometry reduces the penumbra or, "shadow X-ray" that comes from a cone-beam CT. This phenomenon is non-diagnostic and reduces image clarity.

•Detector coverage- NeuViz 16 detectors provide up to 25% more anatomical coverage per rotation than conventional detectors. Because of this, long axis anatomy (i.e. abdomen/pelvis or peripheral) studies, can be done in less time. A shorter scan means a lower radiation dose. 

•High Sampling Rate- The detector sampling rate of the NV 16 allows more image data to be acquired per rotation, shortening scan times. Once again: shorter scan = lower dose.

•Large Detector Element- A large detector surface area makes better use of the available radiation dose, so CT techs can use less.

The Takeaway

If you're looking for equipment that can minimize dose like a 64-slice CT but doesn't carry the larger price tag, the efficient hardware design makes a new NeuViz 16 from Neusoft an excellent option. If your budget has room for you to step all the way up to a 64-slice scanner, Neusoft offers the same detector efficiency in its NeuViz 64.
