Objectives
The purpose of this study was to quantify the reduction in patient radiation dose during coronary angiography (CA) by a new X-ray technology, and to assess its impact on diagnostic image quality.
Background
Recently, a novel X-ray imaging technology has become available for interventional cardiology, using advanced image processing and an optimized acquisition chain for radiation dose reduction.
Methods
70 adult patients were randomly assigned to a reference X-ray system or the novel X-ray system. Patient demographics were registered and exposure parameters were recorded for each radiation event. Clinical image quality was assessed for both patient groups.
Results
With the same angiographic technique and a comparable patient population, the new imaging technology was associated with a 75% reduction in total kerma-area product (KAP) value (decrease from 47 Gycm2 to 12 Gycm2, P < 0.001). Clinical image quality showed an equivalent detail and contrast for both imaging systems. On the other hand, the subjective appreciation of noise was more apparent in images of the new image processing system, acquired at lower doses, compared to the reference system. However, the higher noise content did not affect the overall image quality score, which was adequate for diagnosis in both systems.
Conclusions
For the first time, we present a new X-ray imaging technology, combining advanced noise reduction algorithms and an optimized acquisition chain, which reduces patient radiation dose in CA drastically (75%), while maintaining diagnostic image quality. Use of this technology may further improve the radiation safety of cardiac angiography and interventions. © 2015 Wiley Periodicals, Inc.read more

TL;DR: The AlluraClarity system reduces the patient and primary operator's radiation dose by more than half during complex endovascular procedures (CEPs) and appears to be an effective tool in lowering the radiation dose while maintaining image quality.

TL;DR: Novel dose-optimised fluoroscopic equipment allows longer FT with a decrease in radiation dose to both patient and operator and should allow operators to undertake increasingly longer and more complex procedures and reduce operators' lifetime irradiation.

TL;DR: The new cardiac X-ray system demonstrated a very significant reduction in patient dose with no loss of clinical image quality, and the Phillips Clarity upgrade including improved image enhancement and optimisedX-ray settings significantly reduced radiation without reducing clinically acceptable image quality.
